Papyros® Kiln Shelf Paper is a ceramic-based paper specially formulated for glass fusing. When placed between the kiln shelf and the underside of a glass project, Papyros® prevents the glass from sticking to the shelf during firing. Because of its sturdy composition, Papyros® provides excellent glass/kiln shelf separation on the first use, and frequently even in subsequent firings. Papyros® Paper is extra sturdy and fast & easy clean up.
