Top solutions for today's problems
Our inclusion pigments create shining red, brilliant orange, and intense yellow colour shades in ceramic bodies and glazes, improving the traditional spectrum of colours available to the ceramic world in a unique way.
These inclusion pigments are distinguished by their chemical and thermal stability. This ensures both a high level of production safety and excellent end-product profitability.
The colours of yellow, orange, and red inclusion pigments are achieved using well-known, colour intensive cadmium-sulfoselenide compounds. These possess very limited chemical and thermal stability, and so we encapsulate them in practically inert, colourless zircon-silicate in a complex chemical synthesis process. As a result, our inclusion pigments compare chemically with pure zirconium silicate, yet demonstrate the optical properties of their embedded colour.
Low cadmium content
One of the advantages of these cadmium inclusion pigments is that only a very small amount of cadmium is required to achieve the desired colour. As little as 0.1 weight-% cadmium is sufficient to create strong colours. This is about one twentieth of the amount required to achieve the same colour in conventional cadmium glazes.
1000 times less cadmium released
The cadmium solubility of inclusion pigment glazes is very low. ISO 6713-approved tests for cadmium release show that the cadmium released by inclusion pigment glazes can be a thousand times or more less than that of conventional free-cadmium glazes.
