Packaged under the brand name “Choice”, it comes in a concentrated form which is easily mixed with water to the  desired consistency.

Kiln Wash

Kiln Wash also called battwash or shelf primer is used to prevent glass sticking to the kiln shelves it is fired on. It is quite economical and a 5lb bucket of Bullseye primer will coat one hundred and fifty 129 square cm shelves.
