<p>Just throwing, no pun intended, this out there, could it be wax resist. I have a similar glaze colour and I work in porcelain so I will try it with a wax resist on my next firing and let you know what happens.</p>

<p>Val's Turquoise problem- After using this mug for a while (for coffee), these white specs appear in the cup. (see photo). Could this be a chemical reaction? The glaze should be mature at Cone 6. I soak for 10 minutes at end of firing. Can anyone comment on why the stoneware and or glaze seems to be reacting like this?

<p>I was talking off the top of my head here and leaving out information. It is my guess, not something I know that the Sodium in a high Na flux glaze in solution spreads beyond the glaze and interacts with the iron in the clay to give the toasty edge that you see with some glazes. Since this is on porcelain, in my Gilda moment I say "Nevermind...."</p>

<p>Since a picture is worth a thousand words, that 2nd tile from the left is the Carlton Ball cone 10 Barium, copper matt that I have on my web site. The tile to the right of it is also a copper, barium, matt - a Vivika Heino recipe.</p>
