Controlled oxygen and reducing-agent calcination keeps clay gray for cement use while lowering CO2 emissions and production cost.
A phase-balanced ceramic composition enables faster cutting of large-format tiles with less tool damage while preserving low porosity and mechanical resistance.
Colored glass fragments replace frits and pigments to create jade-like ceramic slate with lower cost, fewer bubbles, and a smoother polished surface.
A refractive glaze composition embeds titanite and high-index oxide to create bright angle-dependent authentication without opacification or white lines.
A copper sulfate and vanadium oxide enamel composition keeps turquoise blue color stable during 700-1000°C firing for consistent post-bake processing.
