What this means is you employ 50 grams of silica and 50 grams of kaolin. In daily observe, potters hurrying to load a kiln, normally just utilize a scoop of kaolin along with a scoop of silica. This isn't technically exact for the reason that silica weighs greater than kaolin, but it is shut plenty of to work.
They decided the amount feldspar so as to add by attempting to rub it off with their finger once the firing. If it rubbed off, then there wasn’t more than enough flux. Extra flux was then included until eventually it took a fingernail to scrape it off. If it took a important or screwdriver blade to scrape it off, there was excessive flux. So, the recipe then results in being:
The just one achievable exception is when firing particular types of kaolin clays that could become molten under correct conditions and bond with the kiln shelf.
