Pyrex glass has boron to give it heat resistance. Fiberglass contains aluminum. Amorphous substances like porcelain and polycarbonate plastic can also count as glass, as can certain amorphous mixtures of metal.

Actual bone cells are attracted to the glass and new, healthy bone can form around it. Martha Foley and Curt Stager discuss.
