Stellaria Posted April 4, 2014 Report Share Posted April 4, 2014 There is a potter by the name of Mark Hudak on etsy that has one of the most beautiful glaze effects I have ever seen. It's a runny earthy green-brown translucent glaze that he calls Fern, and I don't recall seeing anything like it anywhere else. https://www.etsy.com/listing/184456532/pottery-mug-handmade-cranberry-red-and (have a look at some of his other pieces, too - that same fern glaze with purple and cream about made my heart stop ) Have any of you run across anything similar in your glaze work? Obviously I'd not be able to replicate his work, nor would I try, but I'd love it if anyone could point me in any positive direction at all for things to experiment with.

bciskepottery Posted April 4, 2014 Report Share Posted April 4, 2014 Looks to be an ash glaze, cone 10, gas-fired. The purple looks like a copper red in reduction. Link to comment Share on other sites More sharing options...
mregecko Posted April 4, 2014 Report Share Posted April 4, 2014 The posting actually calls out the glaze as a fake ash. Look up Hannah's Fake Ash on google, it's very similar. My guess is the same (or essentially so) base recipe with some tweaks on the colorants. Link to comment Share on other sites More sharing options...
Colby Charpentier Posted April 4, 2014 Report Share Posted April 4, 2014 A fake ash glaze shifts the akali to akali earth ratio in favor of the alkali earth metals to simulate an ash glaze. They're easy enough to formulate, but not always the strongest glaze around. Notice how he's using the ash glazes primarily on the outside of the drinking vessels.

Mistfit Posted April 4, 2014 Report Share Posted April 4, 2014 Fake Ash Glaze Recipe Cone 6, reduction Bone Ash 5% Dolomite 25% Lithium Carbonate 2% Strontium Carbonate 9% Frit 3134 (Ferro) 10% Kentucky Ball Clay (OM 4) 24% Cedar Heights Redart 23% Silica (Flint) 2% Total 100% This is a beautifully variegated fake ash cone 6 glaze. It is a brighter yellow on porcelain with hints of green where thicker, and terra cotta-colored where thin. It is not stable because it is low in silica, but to alter it would change the ash effect. While it does not meet strict requirements of stability, I use it anyway because I substituted strontium for barium. That is from CAD..."Ten Tried and True Cone 6 Glaze Recipes Available for Download! By Diana Pancioli, June 8, 2009" Notice she says it is not overly "stable" so that could be the runny bit.

Marcia Selsor Posted April 4, 2014 Report Share Posted April 4, 2014 I was going to say Diana's Fake ash. Beat me to it. Good resource to use. Marcia Link to comment Share on other sites More sharing options...

clay lover Posted April 10, 2014 Report Share Posted April 10, 2014 Look at Pompeian Ash series, by either Amoco or Spectrum. ^6, comes in 4 ? colors, pretty dependable. Link to comment Share on other sites More sharing options...
Stellaria Posted April 10, 2014 Author Report Share Posted April 10, 2014 I went with Diana's fake ash. Only I didn't notice right away that the test shown in the picture was for reduction, so if I don't like how it looks in oxidation, I'll give Hanna's fake ash a shot.
