- Ceramco3 is a feldspathic porcelain with organic pigments mixed into the powder. - This high potassium formula is much more stable than low-potassium feldspar that has to be “cooked” with other minerals before it can be used. - This stability allows for better individual control, so you can give each of your technicians the freedom to work the way they work best and always achieve predictable results. **For further product information, please contact Chat Support**
