Hello For Flux Sake Listeners! As you know, Matt and Rose do a lot of glaze testing… A lot. They've decided to share some of that testing in their amazing new digital glaze book Test Test Test!:7500 glaze tests from Ceramic Materials Workshop. The book features a broad spectrum of oxidation and reduction glazes including matte, gloss, and crystalline, half of which are at Cone 10 and the other half at Cone 6. Each glaze is documented with images, recipes, and chemistry giving you an opportunity to learn these glazes inside and out. Check it out and don't forget to keep on test, test, testing!
