To Join Stones or Broken Glass (Spell)

From Egyptian Secrets of Albertus Magnus, Joseph H. Peterson edition:

To Join Stones or Broken Glass.

Take mastich, grind it well with pure water, take the piece of stone or glass, apply the mastich to it, and let it dry, then lift it over a fire to soften the mastich. Put the pieces together and they will become perfectly joined.

Or, take gypsum (plaster of Paris) dissolve in albumen (white of eggs) and smear it on the edges that are to be united. This, too, is a good paste.

The grimoire Egyptian Secrets of Albertus Magnus lists this spell.
