One use.
Effect
Spread over up to 9 square feet of stone, plaster, timber, or metal no more than 1 foot thick. That patch turns clear as window glass for 20 minutes, seen through from the spread side only, and stays exactly as solid, as strong, and as locked as it was.
About
Colourless salve in a flat tin, smelling of hot sand and leaving nothing on the fingers.
