Cadmium Color Pigments

Cadmium color pigments are stable inorganic colouring agents which can be produced in a range of brilliant shades of yellow, orange, red and maroon. Their greatest use is in plastics but they also have significant application in ceramics, glasses and specialist paints.

Modern day Cadmium color pigments are carefully engineered products manufactured in regulated chemical plants with full Health and Safety and Environmental permits under responsible care management. They are calcined to a high temperature to convert to the stable hexagonal form before then undergoing a series of further processes resulting in highly stable pigment grade products with controlled particle size, surface area and surface treatment to ensure they are not only correct for colour but also meet extremely low solubility limits.

Cadmium color pigments are specific Cd compounds, with different CAS numbers and REACH registration files.

These substances are specifically excluded from the classification and labelling entries in the DSD and GHS tables covering cadmium compounds. A risk assessment of these products conducted by the EU concluded that these products offer no significant hazard to either human health or to the environment. REACH registration has confirmed that no hazard classifications apply – either for human health or to the environment.

White Enamel Powder for Overglaze Painting

White Enamel for Porcelain, in white powder form in large, 2 dram glass vial with screw on lid.

This White Enamel Powder for all overglaze painting has a high relief and will not pop off. Use the OJ3, Pollyanna Medium for both enamel and raised paste work. Mix to a thick toothpaste consistency with this medium. Then add one drop of pure turpentine at a time until strings. It will make wonderful dots, scrolls – then thin with more turpentine to make longer, even lines (won’t be quite as raised if thinned more) Fire to Cone .017, – .018 1443 – 1386 F, 784 – 752 C

You can add any regular overglaze paint to the enamel to make your own colors! Add the color after the mixture strings – you may have to add some more turpentine (never add more of the medium as that will make it flatten more!) Do not add gold over this Enamel. Use the JTX Josephine Texture Paste – Base for Gold for a white, raised relief which can be covered with Gold or Silver.

Spotlight on cadmium red

Think of the colour red and most likely you will find yourself thinking of the big emotions and that is why artists like it so much. Red is an extremely dominant colour and even a small piece in a painting will catch your attention. It is the colour most often associated with powerful feelings such as love, passion and anger as well as heat, fire and blood. Cadmium red is a very strong, warm and opaque red and in the early part of the 20th century became a natural replacement for the distinctive but toxic vermilion.

Cadmiums have the broadest range of hues derived from any of the inorganic pigment groups. These hues range from pale to golden deep yellows, light fiery to deep oranges through to light bright scarlets to deep reds and maroons.

Moving Into The Red

It was some time after the introduction of cadmium yellow that cadmium red began to appear. The early reds were made by heating the cadmium yellow together with selenium. In 1919 a patent was registered for the production of cadmium orange and cadmium red. The method for this production was to mix cadmium salt solutions with alkali and alkaline earth sulphides and, in turn, to heat the resultant precipitate. For those of us who might not have been paying attention in our chemistry lessons: a precipitate is the solid material or collection of particles that is left in a solution after a chemical reaction and, not surprisingly, the process itself is called precipitation.

Advanced Production Techniques

The production of modern, high performance cadmium red is an expensive and lengthy process requiring only the purest raw materials to produce the best possible colour.

Transforming the cadmium metal into a usable pigment means it undergoes several carefully controlled chemical reactions and procedures using various ingredients including mineral acids, sodium sulphide flakes, water, and selenium. Towards the end of the process heating takes place to create the pigment and it is in this heating process that the quality and hue of the final pigment begins to form. The emerging pigment is then ground down into tiny particles – these grinding processes affect the way the pigment interacts with light. Fine particles have a good diffused reflection and produce a colour that is very strong and vibrant.


Cadmium itself is a heavy metal and is toxic but cadmium pigments are not classified as dangerous for use in line with EC classification. The level of soluble cadmium in the pigments is so low that no hazard warnings are needed and they pose no greater risk after swallowing or breathing in than other pigment types. Cadmium pigments are restricted for certain applications but this restriction does not apply to artists’ colours.

Go Red

Cadmium red will add brightness, strength, opacity and maybe a touch of passion to any artist’s work and is now widely regarded as a viable alternative to the erratic and toxic vermilion either natural or synthesised. Available from Winsor & Newton Artists’ Oil Colour: Cadmium Red and Cadmium Red Deep.

Porcelain Enamel Powder Vs Powder Coat

Spring is lurking just around the corner and you’re getting the itch. Not the allergy kind. It’s more of the itch to give your home a fresh look. And two of the most powerful options at your disposal, even if you’re not an avid DIYer, are color and lighting. So let’s breathe some new life into one of the most used rooms in the house — the kitchen.

Perhaps you’ve grown tired of builder beige on the walls. Bring home some of those sample bottles of paint and splash it around. Be bold! Try something new! Live with it for a week and see how the colors look at different times of the day. With minimal investment, you might just find the perfect shade!

Next, think about replacing those kitchen pendants that your contractor spent a solid 30 seconds thinking about at the big box store. When it comes to lighting, you have many choices but one of the first things you should consider is the finish.

One of the most popular finishes available today is porcelain enamel powder
coating. Powder coating is a dry powder that is applied most often to metals. We apply porcelain enamel powder
coating to an aluminum alloy of a thicker grade than you will find at most retail outlets.

We also prep our aluminum by hand with denatured alcohol which allows the porcelain enamel powder
coat to adhere better. This durable finish comes in more than a dozen different colors ranging from traditional hues of Black, Galvanized, and Rust to more brilliant shades of Barn Red, Buttery Yellow, and Royal Blue so you’re sure to find the right shade to fit your décor.

A second finish option is porcelain enamel powder
which was an industry standard back in the early 20th century. When RLM warehouse shades became the fixture of choice over bare bulb lighting in factories and warehouses, porcelain enamel powder
was used because of its ability to withstand high heat, chemicals, and even outdoor elements. Our porcelain enamel powder
shades are hand-spun from commercial grade steel, then three coats of porcelain enamel powder
glass are also hand applied. The shades are baked in a special oven where temperatures reach up to 1,600 degrees to seal the glass to the steel resulting in a high-gloss finish.

Uses of Cadmium Red pigment

Most cadmium red pigments are used in plastics. These pigments disperse well in most polymers to give high opacity and tinting strength. The pigments are insoluble in organic solvents, have good resistance to alkalis and in most cases will remain lightfast for the life of the plastic. As a result, cadmium red pigments have been used in a wide range of plastic products.

Nowadays, their greatest application is in complex polymers which are processed at higher temperatures and require the unique durability and technical performance of a cadmium red pigment. Their use is almost mandatory in many nylon, acrylonitrile butadiene styrene (ABS), polycarbonates, high density polyethylene, silicone resins and other modern thermoplastic polymers processed at high temperatures which preclude the use of organic pigments and also most alternative inorganic pigments in the range of hues provided by cadmium. Cadmium pigmented engineering polymers such as ABS are widely used in products which include telephones, gas pipes and fittings, electricity cables, beverage crates and motor vehicle radiator fans.

Bright cadmium yellows, oranges and reds are major pigments for artists’ colors where their permanence and opacity are the accepted standards against which other pigments are judged. Cadmium yellows and reds can have service temperatures well above 300 °C and are used in coatings for process chemical and steam pipes. They can also be incorporated in latex and acrylic coatings.
