The best cement for joining pieces of meerschaum, is Egg Cement, which see.
Garlic, crushed to form a sort of dough, is rubbed over the surfaces of the meerschaum to be united; the latter are then bound tightly together with fine wire, and boiled in milk for half an hour.
Quicklime is mixed to a thick cream with the white of an egg. These cements will also join fragments of glass or china.
