Hi. Im somewhat new to glass casting with molds using frit. I have had decent luck in the past but now using some molds that are smaller with more detail. In particular I am trying to cast a small 1.25" cross for jewelry. What Im finding is after I fill the mold and slightly heap the frit, when its done, its really small and not filled. The cross mold has square corners but when I take it out of the kiln, the corners are round and shrunken.
Im using slumpy's full fuse schedule https://www.slumpys.com/Company-Informa ... g-Schedule
Any tips appreciated!
