Found a bunch of old Spectrum Stain jars in the studio.......about 10 years
old. No directions on what to use them with. I tried just water, but didn't
melt correctly.......what else should I add...a frit and GB ? and what
percentage to what ? Thanks Jerry

It really depends on it's intended application and finished look.
Generally......Prepared liquid stains already have a small amount of flux
added. You'll need to test and find the amount that gives you the look you
are after.
Ferro Frit 3124 can be used as a flux to mix with the stains. 85 stain/15
flux is a good starting point for testing.
You could also try using Gerstley borate as the flux.

The more flux added the glossier it becomes.

Hope this helped. Happy firing.
