I use Glossy Base Glaze 1 from Mastering Cone 6 Glazes on a clay body that does seem to give crazing with several other glazes.
Ferro Frit 3134 20
To this I add:
Carboxy Methyl Cellulose 1
I tend to make small batches (small studio and I'm addicted to testing glazes) and brush them on. The bentonite and CMC help make glazes brushable.
