Hotline Primo Primer is a kiln shelf primer, also called kiln wash, that forms a separating layer between your glass and the kiln shelf so fused and slumped pieces release cleanly. It fires to 1550°F (843°C) and higher and helps keep glass from sticking to the shelf. After firing, the primer lifts off the shelf by brushing or wiping with a damp sponge, with no scraping.
