Grace london 8 Posted January 6, 2019 Report Share Posted January 6, 2019 HNY everyone, I have a lovely low matt glaze, but I want to thicken it. So it gloops and drips, perhaps even foam. I've been looking everywhere for a glaze like this. I am a sculptor and I really love this Matt Wedel glaze. Any tips or recipes? Could there be an additive I can use to crystallise my glaze?

neilestrick 4,609 Posted January 6, 2019 Report Share Posted January 6, 2019 It looks like that piece just has a lot of glazes layered on. To make the glaze thicker, either apply more coats, or just leave the lid off and let some of the water evaporate. If you want it to foam, adding a small amount of silicon carbide may do the trick. Some glazes behave poorly when applied too thickly, and will crawl or even fall off the pot, or at the very least will become very runny. And as you can see in the photo, you run the risk of them dripping off the pot and onto the kiln shelves. You'll need to fire everything on waster slabs as you do your tests.

liambesaw 2,767 Posted January 6, 2019 Report Share Posted January 6, 2019 Looks like just really thick application from the crawling I see there. Link to post Share on other sites
Rockhopper 161 Posted January 6, 2019 Report Share Posted January 6, 2019 Also looks like the glaze may have been 'drizzled' on - either by pouring, or with a bulb syringe. Link to post Share on other sites
Min 3,444 Posted January 6, 2019 Report Share Posted January 6, 2019 Matt Wedel Fat White ^06 - ^03 from CM March 2014 Lithium carbonate 11.8 Whiting 24.5 Nepheline Syenite 36.4 EPK 2.8 Silica 24.5 100 For blue: 0.22 copper carbonate, for lavender 0.25 Mason stain 6385 Also uses: Lisa Orr Base Glaze ^06 - 04 Gerstley Borate 9.5 Soda Ash 15.1 (I would suggest dissolving this in hot water before adding to glaze) Ferro frit 3110 63 EPK 4.8 Silica 7.6 100 plus Bentonite 1.8 He mentions using the Lisa Orr glaze for mixing with green stains for his flower stems and mixing the Orr glaze with the above Fat White glaze plus also mixing with commercial glazes sometimes. He uses a large syringe to get the glaze into tight spots and will build up the glaze up to an inch thick. He fires on stilts with a waster underneath. From the CM article re Fat White "When applied thick and on the appropriate surface, it can take on a foamy quality." So this might be the glaze he used in your photo example, worth testing I think.

Lots of fun things you can do on sculptures that you can't get away with on functional pieces Link to post Share on other sites
Grace london 8 Posted January 7, 2019 Author Report Share Posted January 7, 2019 @Min Thank you very much for this info. @liambesaw It's pretty exciting to be glazing sculpturally but it's also a war of attrition, ceramic sculpture.... Link to post Share on other sites
