G2926B is a popular recipe that saw alarm during 2021 because of the difficulty in getting Ferro frit 3134. This motivated us to get a supply of the Fusion equivalent, F-12.

Not only does the test compare the degree of melt but also surface reaction to LOI (defects), iron content and melt surface tension.
