Beginning at the potter's wheel, Radca works with as much as 50 pounds of clay to produce plates over three feet in diameter - something few potters have been able to master. The warmth and splendor of Radca's pieces are attributed to his carefully developed firing process. Color and effects result from controlling the temperature of firing and by introducing combustible materials to the kiln environment near the end of the firing process - a process he calls "Painting with Fire."
After the plates are fired and allowed to cool, Radca applies muratic acid that eats away at carbon buildup and exposes the color underneath. It took years of exploration for Radca to perfect this technique, as well as his unique firing process.
