An SW Art Glass Exclusive - This earthenware ceramic Vitrigraph Pot was developed to improve the yield of murrini and millifiori produced using Phoenix Forms. The Vitrigraph Pot has a base hole in it of approximately 7/8 of an inch. Its dimensions are 5 inches in diameter and 5-1/2 inches tall, which makes them good for use in smaller vitrigraph kilns. The bottom of the Vitrigraph Pot has a 1-7/8 inch flat foot for stability and sitting in the hold in the bottom of your vitrigraph kiln. These pots have been fired to 1860F during production, so no shrinkage will occur during use.
