The paper in this pad is really lovely, and it’s going to make a great sketch journal while I’m traveling. My only complaint is that the backing cardboard isn’t as thick as the description seemed to say. If I held the pad at the bottom, out flat, the top would bend back. Luckily, I have some really heavy chipboard, and will just slip a sheet of that in there.

It wasn’t until recently that I was introduced to Rhodia products, and I’ve fallen in love with them. The pages have a smooth finish that has just enough bite, and takes ink very well. So far, I haven’t experienced bleeding with my fountain pen or dip pens. I never knew that I could enjoy a pad of paper this much.

Rhodia Pad Holder Review – Writer’s Bloc Blog

Rhodia Pad Holders are like classy dinner jackets for your Rhodia notepad! Over the past couple of years Rhodia has expanded their selection of orange and black pad holders to fit 8 different sizes of Rhodia pads. If you’re a fan of Rhodia’s iconic super-smooth graph paper, you may be wondering if one of these pad holders with pen loop should be adorning the top of your desk.

The Rhodia pad holder is made of a lightly grained leather-like material with an embossed Rhodia logo on the front cover. The cover is stitched together around the edges with matching thread and the exterior comes in either bright orange or classic black.

The cover material is quite durable and is an attractive way to protect your Rhodia pad especially if you like to toss it in your purse or carry it in a pocket or briefcase.

The interior of the pad holder is black and has 2 pockets. One pocket is designed to hold the back cardboard cover of your Rhodia pad and the front cover too – if you flip the front cover back behind the notepad it will hold it out of the way. The other pocket is there to hold business cards, notes, receipts or whatever you want to save or keep handy.

The cover itself is flexible, so if you’re looking for a stiff-as-a-board cover with firm support this is not it. However, the cover definitely does add some support to your Rhodia notepad while you are writing.

Originally, Rhodia pad holders did not have a pen loop, but this is now a standard feature on all of the newest covers. The pen loop seems to be made out of the same material as the cover so it is not stretchy like an elastic is. This loop must have been designed specifically to hold the triangular Rhodia pencil since it fits perfectly, so perhaps this should be called a pencil loop instead. A slim pen such as the Pentel Slicci gel pen will also fit in this pencil loop. It’s a practical feature if you need to have a writing instrument on hand at all times.

Are you using a Rhodia Pad Holder? What size do you use and what particular writing instrument do you keep in the pencil loop?

Rhodia Pad Holders are currently available in these sizes:

3.5” x 4.5” (fits Bloc No. 11)
3.75” x 5.25” (fits Bloc No. 12)
3” x 8.25” (fits Bloc No. 8)
4.5” x 6.25“ (fits Bloc No. 13)
5.75” x 5.75” (fits Bloc No. 148)
6” x 8.75” (fits Bloc No. 16)
8.25” x 11.75” (fits Bloc No. 18)
8.25” x 8.25” (fits Bloc No. 210)

Rhodia ‘R’ Pad No. 16 Orange

This is a review and drool-fest of the new Rhodia Premium “R” Pad No. 16. It’s long overdue but I’ve been really under the weather. I eventually lost to the flu and decided to lie around and do nothing to let my body recover! As soon as I felt well enough, I pounced on this review! Ok. Let’s do a run down of the technical stuff so I can move to the juicy bits! As I mentioned, I won this beauty in a giveaway held over on Rhodia Drive. Many thanks to Karen at Exaclair for the great giveaway!

Features:

Notepads with “Soft Touch” coated cover
90g smooth ivory paper
Ruled
70 sheets
Top bound – cover is scored to fold back neatly
6 x 8 1/4” (14.8 x 21 cm)

Two covers: orange with black inside, and black with orange inside

It’s no secret that I am madly in love with Rhodia. I just love everything Rhodia I’ve ever tried. But when I tell you that this notepad makes my heart beat faster, you better believe it’s racing. WITH LOVE.

  Begin the drool-fest.

The new design is premium. It looks expensive. I mean, Rhodia screams premium regardless of what you have but the new “R” pads are truly cool.   I realize it’s just a simple little R in the bottom right hand corner of the notepads but it looks cool. It adds pizzazz and makes you think “limited edition”. Draws the eye – “depuis 1934”. Oooo français!

The R pads stand out to the naked eye from other Rhodia products because of the new soft touch coated cover, and it’s awesome. It’s soft and smooth, and, with the orange cover that I have, it doesn’t scuff as the Webbie or Reverse Book covers do, but it can be scored such as with sharp objects. Both the outside (orange) and inside (black) are matte. The black inside looks like really, really smooth dark volcanic rock…but velvety volcanic rock. And the whole thing is velvety soft, like a peach!

  You can see the difference between the new soft touch coated cover and the normal covers of other Rhodia pads. I used the flash on purpose to show the reflection of the Bloc No. 11 (top) whereas there is no reflection off the R pad’s cover (matte, bottom).
 
The size of Pad No. 16 is perfect. It’s portable but big enough to be useful for whatever you want – notes, journalling, doodling… Fits into most purses (unless you carry a teeny tiny clutch-type purse). Doesn’t fit into pockets (like the itty bitty adorable No. 11) but who cares?? It’s so gorgeous you’ll want to hold it and flaunt it anyway. I love it. And for the ADD in me, it’s the perfect size and amount of pages that I can actually fill it up without getting terribly distracted by another Rhodia notepad.

The whole pad has micro perforated pages – easy tear out. I have never had the need to tear out a page to give away or leave a note or whatever. I also wouldn’t have the gall to tear a page out and part with it, but it’s available if I need to. The micro perforations are pretty clean for tearing out so it won’t leave your notepad looking like you haphazardly ripped your pages out. In addition, the perforations make folding the pages back a perfect art. I hate when I fold pages in a notebook and it ends up crooked. Am I the only one who experiences this frustration? Anyway, the perforations at the top of the page are convenient for tearing out but also for maintaining order.

  On that note… the top bound cover is scored to fold back neatly – thank goodness for this because the idea of having to fold this sexy (…I’m sorry. I couldn’t help myself…) cover back in a way that may have been uneven would be too much for me to bear. This is great if you like drawing or writing outside where sometimes the wind can pick up and blow your cover closed on you while you’re trying to write – very annoying. Plus, having the scoring for folding ensures the notepad still looks good after it’s folded. The cover doesn’t tear or fray from repeated folding!

Score lines on the front cover for easy folding 

The pad also lays flat! Glory Hallelujah! One of the cons, if you want to call it that, about the Webbie for me was that it didn’t lay flat. Not really a huge deal because I’m a big Webbie fan as it is but the way the R pad pages fold back is very tidy. The front cover folds back completely with two scored lines and all following pages tuck under just as easily. Furthermore, the back cover is reinforced with cardboard so that it feels like you’re writing on a mini-clipboard – makes writing when you’re walking around a cinch!

Another obviously giant point worthy of drooling: the paper. The ivory paper is warm, classy, and elegant. Combined with a fountain pen (if you’re into fountain pens, that is), you’re going to fall madly in love with this notepad and it’ll make you feel like a million bucks. The paper is divinely, satiny smooth. When I pet it (yes, I do pet the paper), I picture really rich, creamy, silky chocolate cascading down a chocolate fountain (didn’t I say this would be a drool-fest?). *Sigh*. There are no markings on the paper aside from the ruling; it has a very clean appearance.

More on the paper – 90 g Clairefontaine paper is solid. As I begin to explore fountain pens and inks more, my appreciation for paper that makes the writing experience outstanding continues to grow. This paper is thick enough to prevent bleeding with almost all of the pens I tested, but doesn’t feel like paper stock which tends to lack flexibility.

Premium paper tends to add a few seconds of drying time to inking – this is not uncommon and it’s well worth it. It enhances the luscious qualities of my inks. No feathering on this paper makes the lines pop – sharp with contrast.

    This paper can take a beating. I accidentally dripped a huge blob of J. Herbin Vert Olive ink onto the paper and it just barely bled through. Fountain friendly paper, without a doubt.

This is the side of the ink blob (top left corner) that I tried to disperse

Note the bleedthrough from my blob of ink

I do not write heavily with fountain pens but Shangching (East…West…Everywhere) has a great review of the R pad and reports that even with heavy writing, the paper handles it and only shows an imprint of the line. Because I write lightly with fountain pens, I didn’t even see any lines on the back sides of the pages written on.  

This paper is also very micro tip friendly. I have mentioned before that premium paper (Habana & Webbie) are micro tip-friendly because they are so smooth that the fine tips of pens like Pilot Hi-Tec C and Uni-ball Signo DX/RT glide across the paper allowing ink to flow smoothly, and does not scratch and collect fibers that clog the tip.

  Sometimes I wish I could go back to school just so I can use notepads like this. You know, so I’d have enough writing to do that I could fill it up quickly… and get another one. I know, it’s a sick, nonsensical illness to be addicted to filling up journals and notepads but to each his own!

I hope Rhodia adds dots to the rulings! So far, there is blank and lined but seriously, dot rulings are my favorite and it would just … wow. A dotPad “R” would knock my socks off. 

Price:
Writer’s Bloc – $6.65
Goulet Pens – $7.00 (with quantity purchase discounts. See? It’s better to buy more.) 

Overall:

At this point, if you’re wondering if you still need to try the R pad, allow me to smack you with my own R pad and scold you for hesitating. Fill it with your hopes and dreams, or school notes, or doodle and sketch! Anything! You’ll love it! I’m sure as much as I do!

90,000 Platinum, palladium or rhodium – what is the best investment and how to do it :: News :: RBC Investments

How the group of precious metals has earned the favor of consumers and investors, will tell the head of the metallurgical and mining industry at VTB Capital Dmitry Glushakov

At the mention of the word “platinoids” platinum comes to mind – a precious metal, the most expensive in jewelry stores. In fact, the family of platinoids is more diverse, and platinum is now far from the most honorable place in it. Not only is it cheaper than gold, but also much cheaper than other metals of the same group – palladium and rhodium. How have these materials earned the favor of consumers and investors, which has allowed them to rise in price by 5-15 times over the past five years?

Demand for palladium and rhodium

Although formally palladium and rhodium are precious metals, in fact they have long become industrial metals, because more than 85% of their consumption falls on the needs of the automotive industry.This shift has taken place over the past ten years, when manufacturers of catalysts for automobile exhaust systems began to massively use these two metals. Now, almost every exhaust system contains a fairly large amount of rhodium and palladium, which are responsible for trapping combustion products and substances coming out of the engine and polluting the surrounding world.

Photo: RBC Investments

Recently all over the world there has been a merciless struggle for the purification of city air.All regulators are tightening the requirements for the amount of pollutant emissions from cars every year. This is how the standards Euro-5, Euro-6, China-5, China-6 and others appear, which are updated in different regions at different intervals, but each time they require more and more strict emission control.

“I would not expect growth above $ 28-33. ” What will happen to silver in the coming years

For car manufacturers, this means more and more palladium and rhodium have to be added to their exhaust systems.This explains such a growing interest in these metals, which are almost never used anywhere else. At the same time, their production practically did not grow in recent years, and the historical reserves in Russia and Switzerland came to an end, which led to a rise in prices.

Photo: RBC Investments

The main risk for palladium demand is, oddly enough, the actions of the same regulators, but this time in the fight against climate change. In accordance with the Paris Agreement, all countries of the world must significantly reduce greenhouse gas emissions, primarily carbon dioxide (CO 2 ), and cars with internal combustion engines are one of the largest sources of emissions. The main way to reduce emissions is seen as the widespread replacement of cars with internal combustion engines (ICE) for cars with electric motors. Regulators are trying by hook or by crook to make ICE cars more expensive and electric cars cheaper for consumers.

In Russia, for example, there is no import duty on electric cars, owners do not pay taxes for their electric cars, and parking in Moscow is free for them, not to mention the fact that electricity is cheaper than gasoline. As a result, the growth of the electric vehicle market all over the world is progressing at an outstripping pace, this is due to the reduction of the classic market.

Palladium mining (Photo: RHJPhtotoandilustration / Shutterstock)

According to our forecasts, the market for cars with internal combustion engines (as well as the demand for palladium and rhodium) will stop growing from 2024, and from 2025 it will start to gradually decline. Electric vehicle production has grown at an average rate of 50% per year for the past five years, and in 2020, electric vehicle sales accounted for 3% of total sales. But if these rates continue, then in 2025 their share will grow to 15–20%, and the number of cars sold with internal combustion engines will begin to decline, which in turn may lead to a decrease in demand for palladium and rhodium.

Demand for platinum

The situation with platinum is not so obvious. The structure of demand is quite diversified, and autocatalysts account for only about 40%, while jewelry – 30%, and the remaining 30% are divided between applications in the chemical, glass, electrical, fuel industry and medicine.

Photo: RBC Investments

Platinum-based catalysts are actively used in diesel cars (palladium and rhodium in gasoline), and after the “diesel gate” that occurred five years ago, the production of diesel cars in the world and, as a result, the consumption of platinum in autocatalysts decreased by 25%. This is what caused the price of platinum to fall since then, while the prices of rhodium and palladium have risen severalfold. At the same time, according to various sources, platinum reserves in the world range from six months to two years of world consumption, so no critical deficit is expected in the coming years. Potential dark horses for platinum demand include hydrogen engines, another competitor to ICE engines.

Gold GOLD

$ 1,759.3 (-0.02%)

Hydrogen fuel cell technology is being developed in parallel with electric vehicles and also significantly reduces emissions of harmful substances and greenhouse gases when using a car. In the future, this technology can become a big consumer of platinum, which is actively used in it. While the rate of growth of production of such vehicles lags far behind the rate of growth of production of electric vehicles, but both markets are currently very small relative to the market for cars with internal combustion engines, so it is premature to draw conclusions about which technology will win.

The plans of the main regions look aggressive: in the EU – 5 million cars with hydrogen engines by 2030 (now 1400), in China and the United States – 1 million cars each by 2030.But for now, it looks like electric cars will win, and most of the efforts of states now fall on the development of infrastructure for electric cars, and no one will invest in parallel in infrastructure for hydrogen engines.

Platinoid production

From the point of view of the production of platinoids, the situation is very simple, because the world production is concentrated in several key regions. South Africa produces 50% of the world’s platinoids. Norilsk Nickel – 30%, and the rest of the production is divided mainly between Zimbabwe and North America.At the same time, platinum and rhodium prevail in production in the southern hemisphere, while most of the palladium comes from the northern hemisphere and 40% of the world’s palladium is produced by Norilsk Nickel. Investment in production growth has been minimal over the past decade due to low metal prices, so global production has stalled and even declined in South Africa.

Photo: RBC Investments

This ultimately played into the hands of prices – the growth in demand for palladium with stagnant production eventually led to a deficit of palladium in the world in the amount of about 10% of the market. For several years, the resulting deficit washed out the reserves of metal in Russia and Switzerland, which ultimately led to an increase in prices. The market may remain in deficit until 2025, so the price of palladium could hold above $ 2,000 / oz for a few more years, and investment in this sector looks preferable to investments into platinum.

How to invest in platinoids?

Both metal mining companies and ETF – funds.In the first case, you can pick up a portfolio of metallurgical companies with a large share of platinoids in revenue. For example, platinoids account for about 50% of Norilsk Nickel’s revenue, with palladium and rhodium accounting for most of it. Sibanye-Stillwater has , which have assets in South Africa and North America, palladium takes 39%, platinum – 15%, rhodium – 34%, and the remaining 13% is gold. You can also consider Impala platinum , Anglo-American platinum , Northam and Sylvania Platinum , the production of which is mainly concentrated in South Africa.

As for ETFs, that is liquid palladium ( PALL US ) and platinum funds ( PPLT US ). Recently, another interesting tool for cryptocurrency lovers has appeared – palladium tokens in the Norilsk Nickel palladium fund on the Atomyze platform. So far, this tool is available only to large industrial consumers, but the company plans to expand the circle of potential investors.

More details 90,000 What is rhodium? | MY JEWELER

Noble metal of the platinum group. Thanks to the cold white shine of this metal, rhodium is ideally combined with any inserts from diamonds to cubic zirconia. With the help of rhodium plating, it is possible to reduce the wear of the product by increasing its hardness, protect the jewelry from scratches and tarnishing, the effects of aggressive factors – water, radiation, friction.Recently, there has also been a tendency when rhodium plating is applied to a product made of white gold.

I would like to tell you more about rhodium.

Rhodium (Rh) can be found in the periodic table under atomic number 45. It is a hard metal with a silvery color and belongs to the platinum group metals. This group also includes palladium, platinum, ruthenium, osmium and iridium. Some of these metals are radioactive, such as osmium, which is not used in the jewelry industry.As for rhodium, it is used only as an additive to the ligature, to increase the strength of the product, to give a noble white tint to products made of white gold and silver, sometimes they are also coated with platinum products.

The pioneer of rhodium is believed to be the Englishman William Hyde Wollaston, who discovered it in 1804, as well as platinum (1803) and palladium (1803).

In the natural environment, it does not occur as its own mineral. It can only be isolated from any of the rhodium-bearing ores.It can also be found in native Pt, as well as in the group of osmous iridium. Rhodium impurities can be found in compounds of platinum metals, for example, sulphide, antimony, arsenic, which are usually located in places where copper-nickel sulphide ores are concentrated. The richest are the deposits in South Africa, Mexico, Canada, Russia. In 2012, the volume of supply of rhodium in the world market amounted to 21.9 tons. The leading positions in this indicator are occupied by South Africa -18.0 tons, Russia – 2.2 tons, North America – 0.7 tons.

An important feature of Rhodium is its weak interaction in reactions with other chemicals and minerals. Under normal conditions, it practically does not interact with any substances. It can be dissolved only under heating conditions using “aqua regia” (a mixture of nitric and hydrochloric acids in a ratio of 1: 3). The melting point of rhodium is 1966 degrees Celsius, the boiling point is 3670 degrees, and the electrical conductivity is 19 Hg = 1. It is this property that jewelers have adopted – after applying a thin rhodium coating to a piece of jewelry, it becomes very resistant to external damage.

Rhodium exhibits a high light reflectance, about 80%, which makes it simply irreplaceable in jewelry production. It stays in the region of 3-12 months, it all depends on the wear of the product and on many factors, the peculiarity is that at any time you can cover the product with rhodium and it will be like new.

90,000 Why rhodium is getting more expensive

In early 2020, the price of rhodium rose by a record 65%. At the end of March 2021, its price is $ $ 884 per gram.For comparison: gold is priced at $ 55 , silver is worth $ 0.80 . And while many follow the stereotypes, thinking that is the most expensive metal in the world – platinum (almost $ $ 38 per gram), let’s figure out what is the secret of the “success” of rhodium.

Rhodium in bars and coins is not as common as gold and silver

What is rhodium

The most expensive platinum-group metal used to coat jewelry to increase its durability and shine.Fun Facts:

  • Rhodium has a higher melting point than platinum: 1963 ° C and 1768. 3 ° C.
  • In its pure form, the metal is rare; it is extracted from platinum in a complex way, by treating with acids in porcelain pots for 24 hours.
  • A private US mint issues a pure rhodium coin for the first time in the world.

Rhodium was discovered in the 19th century, but is still not as well known as platinum, gold or silver.Although it is he who now plays an important role in the global economy, although lovers of jewelry may not even guess about such an important mission.

Why rhodium rises in price

Reason # 1

The demand for cars with engines that meet the new environmental standards of Europe and Asia has grown exponentially. Rhodium is a key element in the manufacture of catalytic converters that reduce pollutant emissions.


What is a catalytic converter? This is a three way catalysts (TWC) aftertreatment system. It is rhodium that decomposes toxic combustion products. Metals costs for one palladium and rhodium based converter range from $ 35 to $ 70 .
More than 85% of all mined rhodium is used for the automotive industry, according to Johnson Matthey Plc , the world’s largest distributor of platinum group metals.The rest belongs to the chemical, glass (reflective properties of the metal) and jewelry .
What does this mean? Rhodium today plays a role in the industrial industry, and not in the jewelry sphere as a precious metal.

Reason # 2

Termination of deliveries. Market demand leads to a boom in raw materials production. For example, shutdown Anglo American Platinum resulted in a 16% cut in rhodium shipments in 2020.This is also influenced by the COVID-19 pandemic: outbreaks of the disease also cause a number of restrictions in South Africa (80% of all production), the leading producer of rhodium at the moment. Additional challenges, such as the lack of reliable infrastructure for energy production and geopolitical instability in South Africa, also seriously affect production.

Forecasts of market experts

While rhodium is currently on the rise, it is important to remember that its price is highly volatile in the context of history.Therefore, businesses are still hesitant to increase their production of rhodium: if its value suddenly changes, the production of rhodium will turn out to be poorly recouped. On the other hand, without new suppliers, the rhodium deficit is likely to persist for at least another 3-4 years. It is also predicted that the value of rhodium will eventually decline as internal combustion engines are replaced with batteries to power vehicles, but this may not happen so quickly.

In total

Rhodium is currently experiencing a skyrocketing price of , but it is important to be well aware of the factors that determine its value before deciding whether to invest or sell rhodium. Historically, rhodium has been an unstable precious metal. Until recently, it was impossible to even buy it in bullion form. And coins are even more rare due to the refractoriness of rhodium.
