For the Bowl, the wax mold was attached to a clay reservoir. The weight of the wax was 192g, and by water displacement, equivalent to 571g of clear System 96 furnace pellets, and I used that glass in the mold.

The mold was 7″ x 7″, 60% Silica, 40% Plaster, and poured.

For the goblet Stem, the wax mold was again attached to a clay reservoir. The mold was 4.5″ x 5″, poured into a plastic pineapple container. The wax weighed 89g, and was equivalent to 270g of furnace pellets, for the casting, I used 275 clear cullet, and 20g powder (Colour RW HP229).

Both molds were poured and steamed on December 1st, and Firing started on December 1st in Kiln #4 on the following schedule:

1. 3:00 – 150
2. 15:00 @ 150
3. 22:00 – 515
4. 25:00 – 600
5. 25:01 – 875
6. 30:00 @ 875
7: 30:01 – 515
8. 38:01 @ 515
9. 55:01 – 400

The goblet stem was picked up in the hotshop on December 9th, it was sent up to 515C over the course of 5 hours, then soaked for one hour, then sent up to 560C before being picked up and attached to a bubble and re-annealed on a normal annealing schedule for blown work in our studio.
