Judith B Posted December 5, 2014 Report Share Posted December 5, 2014 Today I was visiting Janaki Larsen's store in Vancouver, and was amazed by the glazes she uses. The textures of the glazes are intriguing, really. My question is, how does she get this bubbling effect though? Is it by adding something into the glaze? Is it a specific way of applying it? If anyone around has an idea about how to do that, I'd love to hear about it! Link to comment Share on other sites More sharing options...
bciskepottery Posted December 5, 2014 Report Share Posted December 5, 2014 These are called crater glazes or lava glazes. Generally achieved with silicone carbide in the glaze. These need to go on thick, as in applied with a palate knife. Many pieces are multiple fired until you get the effect you want. Also check out Virginia Scotchie.

Biglou13 Posted December 5, 2014 Report Share Posted December 5, 2014 Hard to tell without color. Partly looks like shino brain crawl. http://ncclayclub.blogspot.com/2010/03/cous-cous-shino.html Link to comment Share on other sites More sharing options...
Chilly Posted December 5, 2014 Report Share Posted December 5, 2014 I get something similar with two commercial glazes, Heritage Silver with White over the top fired to ^06. Link to comment Share on other sites More sharing options...
drmyrtle Posted December 5, 2014 Report Share Posted December 5, 2014 Isn't this one of these sculptural glazes? This is called jujube white from Georgie's Clay (glw15). I think the strong contrast is from under slip or a dark clay body. Link to comment Share on other sites More sharing options...
Babs Posted December 5, 2014 Report Share Posted December 5, 2014 When you click on the image it is labelled 2% lava so I think i is the Silicon Carbide addition that is creating this effect. Link to comment Share on other sites More sharing options...
Judith B Posted December 5, 2014 Author Report Share Posted December 5, 2014 These are called crater glazes or lava glazes. Thank you so much I will definitely check these out. Cause yes I know that applying glazes very thick can give some texture but what Janaki uses is really totally 3D while even when I layer the glazes very thick it still stays pretty flat. But I guess it depends on the glazes too. I checked Virginia Scotchie's work too and the textures on her stuff are amazing! Thanks! Link to comment Share on other sites More sharing options...
Nancy S. Posted December 16, 2014 Report Share Posted December 16, 2014 I believe Coyote has a series of crawl glazes. :-) Link to comment Share on other sites More sharing options...
blayne knox Posted December 26, 2014 Report Share Posted December 26, 2014 Magnesium carbonate glazes will give you a crawl. The more fluid the under glaze or undercoat is, the wider the crawl. Silicone carbide will give the volcanic ruptured look. ( I find the Magnesium better as it is not so rough and sharp.) If you decide to use Carbide then get the finest ground you can lay your hands on. Link to comment Share on other sites More sharing options...
