(CTL) Crystaltex

AMACO Crystaltex (CTL) glazes are low-fire Cone 05 glazes known for vibrant colors and unique surface effects created by fired-in crystals. They produce striking bursts, speckles, and flowing patterns. Many are AP Non-Toxic and ASTM D-4236 compliant, but some (labeled CL) are not food safe—check labels before use. Perfect for adding dynamic, expressive finishes to low-fire ceramics.
