Looking for a cream or white glaze with dark speckles
Posted 27 February 2013 - 03:31 PM
I'm looking for cream or white glaze that has dark colored speckles in it. I am firing to cone 6 in an electric kiln, and am not really comfortable mixing my own glazes yet, so I am hoping to find something commercially available. I've looked at coyote, continental, spectrum, amaco, and duncan and so far haven't had any luck.
I've seen pottery with such a glaze before, which is what prompted this hunt. Does it exist? Does it not exist? Is it a product of minerals in a particular clay body leaching through a regular white glaze, and is THAT why I can't find it?
Any help ya'll can give would be wonderful, I really feel like I'm going batty hunting for this thing....

A little heavy on the speckles, but much closer to what I'm looking for, thank you for the suggestion!
If it is manganese in the clay body, would that leach through in an oxidation atmosphere, or is that something that would require reduction firing to achieve? (sorry, I'm only about two steps up from a glaze/kiln newb)
In either case, I suppose the answer is MORE TEST TILES!

You might consider adding some ilmenite to your white glaze; the ilmenite should give you brown speckles after firing.

Tucker has speckled smoothstone, which is a white clay with lots of specks.

if you already have a white base glaze, try adding granular/milled ilmenite or granular manganese - and it will give speckles.
Make certain to stir often as these granular materials will settle out quickly.
