This page lists some matt and satin matt Cone 6 Oxidation glazes. Some of these I like, some I haven't tried but plan to try them. Matt glazes are hard to use with functional pottery because most matt glazes tend to mark with silverware. They also may discolor (leach) more with high copper when in contact with acid foods. So you have to be creative to figure out good ways to use them if you are a functional potter. If you like to fool around with glaze testing, you may want to read Tony Hansen's comments on matt glazes.
