G3948A has stopped working. It is early 2023 and we have mixed it again multiple times and each time it is firing this ugly brown! I have each original mix ticket and have triple-checked each. I have tested both frits using a GBMF test and they are not mislabelled. The other materials are from the same 50lb bags.
We are testing a possible reason: Frit 3249 could have been used instead of Frit 3134 in the G3948A initial recipes. The extra MgO it supplies could have been the reason for initial success.
