Cone 10R porcelain (left) vs cone 03 porcelain (right)


Thursday 27th October 2016

Want to make this incredible insight-live.com/glossary/71">porcelain and glaze yourself? Read on. The mug on the left is a cone 10R (2350F/1290C) porcelain (#6 Tile kaolin and Nepheline Syenite) with G1947U clear glaze. The other is a fritted cone 03 (1950F or 1065C) porcelain (NZ Kaolin, Ferro Frit 3110) with G2931K clear glaze. We call the body/glaze/firing system "Zero3" (google it or use the links here). The Zero3 porcelain is blue-white instead of grey, the glaze is crystal clear, underglaze colors are so much more vibrant. This Zero3 mug was fired in 3 hours (cold-to-cold). It fits glazes really well, it is very strong and much more translucent. How is this possible? The magic of the frit, it melts so much better than nepheline. It is the most expensive body you will ever make. But from it you may create the highest quality ware you have ever made using the most plastic body you have ever thrown! Follow the instructions carefully.
