M&M Glaze match {Cantello} Custer 'spar 15.4 Barium carb. 33.3 Zinc ox. 15.3 Lead monosilicate 20.3 Silica 8.3 Pearl ash 2.9 Glo-max kaolin 4.5 Add: Rutile .6 Copper carb. .1 Chemical Analysis: Na20 .02 Al203 .09 Si02 .88 K20 .08 Ti02 .14 Zn0 .39 Fe203 .01 Ba0 .35 Pb0 .15 Cu .02 I fire 275F/hr to 2385F, hold 12min. It came out a very nice soft satin matte pale lime green color. It had very few and very small crystals on top of the form. My thought is that I over-fired this glaze by about three cones. It's my guess this glaze should be fired in the cone ^9 range. Anyone care to test? Jesse? Did Bill give a temp with his glaze ? ___________________________________________ <a href="http://jessehull.com/" rel="nofollow"><strong>Jesse Hull</strong></a> says: Chris, Ramping 275F/hr, with a hold of 12min at 2385F equates to an Orton ^11. As per a test at ^9, I rarely fire below ^10.5 any more. I may try it --however the only lead I currently have is either in the <em>Bisilicate</em> or <em>Borosilicate</em> forms. Lead (Mono)Silicate is roughly 85% PbO & 15% SiO2. I wouldn't want to throw Boron into the mix, and the Bisilicate form has 35% SiO2... easily enough to throw the test off without being recalculated.

Bill sent me some pics for the article, and told me that the formula didn't include the MM frit or Lead. All I know from conversations and visits to his facility is that the glazes are gorgeous and fairly consistent. ~jesse.
