PAPYROS Kiln Shelf Paper is a specially formulated, ceramic-based paper to be used between the kiln shelf and the underside of a glass project to prevent the glass from sticking to the shelf during firing. It is porous and allows air to circulate, reducing the chance of bubble formation between the shelf and the glass. Papyros is sturdy and does not turn to dust during firings and can oftentimes be used more than once.
