Some of the students at the Arts Center where I teach use a 50/50 mix of
commercial clear and water applied thin in one coat over underglazes for
good result.

Here are a few to get you started. All are from Jeff Zamek, and every one
of his recipes that I have tried has been pretty much flawless. Buy his
books! Good luck.

here are 2 from Cushing's handbook. the one with the spiral binding.
if you can find a copy of this handbook it is a great studio resource
the results can differ depending on the claybody you use
vc500 is not matte ,but can produce a lovely satin
these are both for cone 04, i believe
VC500

use 1.5-2% bentonite if need be
