Fusion Frit F-19 is said to be a substitute for Ferro Frit 3124, for this particular glaze that appears to be true. The Arbuckle Majolica glaze was applied on Plainsman L210 and fired at cone 04 (but not as thickly applied as would be customary on Majolica ware). On the left is the one with Ferro Frit 3124, on the right is the one with the F-19. The recipe is based on Ferro Frit 3124 and adds 20% of a feldspar neheline mix (likely to increase thermal expansion because it shivered on the original clay body). It is suspended by 10% kaolin. This may craze on your clay body, the G1916Q thermal expansion adjustable transparent base might be a better solution (it responds similarly to a zircon/tin addition to opacify).
