Asbestos Sheets

Rio Grande 2003 Tools and Equipment catalog, page 78, item C are
asbestos free sheets for lining flasks with high temperature
casting. The description reads “Use asbestos free sheets in flasks
that must cool at room temperature. The liners help you remove
investment from flasks.”

Just happened to notice them and thought of this post. Hope it
helps. Usual disclaimers etc. etc.
