Purple has long been a symbol of luxury and exclusivity. In ancient times, its rich hue was so rare—extracted painstakingly from sea snails—that it was reserved solely for royalty. While modern chemistry has made purple pigments more accessible, the color still comes at a high cost. In ceramic decoration, creating an authentic purple glaze requires one of the world’s most coveted and expensive materials: gold. 

In April 2025, gold prices reached an all-time high of $3,177 per ounce, and experts believe its value will continue to rise. As costs soar, manufacturers in the dinnerware and specialty glass industries are increasingly challenged to maintain color consistency and production efficiency. Many hues like rose, magenta, red-violet, deep red and purples traditionally required gold to produce their rich tones, but as prices increase, so does the challenge to produce these colors affordably.

Turn the tables on tradition

Recognizing the limitations of relying on a single, high-cost and finite resource, our Performance Coatings team developed a series of gold-free purple onglazes. Engineered from a unique blend of pigment and glass, these onglazes replicate the depth and tone of gold-based glazes, without the need for gold. This innovation provides manufacturers with greater flexibility and resilience in an increasingly volatile market. 

When used in our lead-free decorative series, our gold-free purples meet strict health, safety and environmental standards and satisfy regulations for food contact materials including: 

These purples provide a sensible option for dinnerware manufacturers, without compromise
