Window panes of glass (vitrum) mica plates (lapis specularis) and similar materials were by no means rare in ancient times.

It is supposed that woad was "vitrum" the dye with which Caesar said almost all the Britons stained their bodies.

Si tanti vilissimum vitrum, quanti preciosissimum margaritum!

The vitrum ceratum antimonii proved often too rough a Medicine, and therefore we laid it almost entirely aside.

Gleini nadroedd (possibly amulets) and vitrum have been found here.
