Making glaze from scratch is not one of my favorite studio activities. It involves measuring large amounts of powdered chemicals materials like oxides, silica which is powder glass and more. It's really just like following a bread baking recipe but some ingredients are toxic and I have to wear protective gloves and mask. Once glazes are fired and melt together in the kiln it's of course very food safe. I don't use any chemicals in my glazes that are not safe after firing. With that said I made new glazes. I want to change my palette just a bit and add some pink and yellow shades to my new work.
