A place to read. The historical definition below, 1650 dictionary, unnumbered definition page 22; facsimile PDF page 350.

Historical Definition

Fel vitri is the scum of glass.

Meaning

The term names a portion or product through its relation to glass. The definition does not give its composition, a particular glass-making process or a use. “Scum” preserves the source’s spume without deciding exactly what material a historical specimen contained.

Use in the Book

Anathron discusses a salt growing upon rocks and rejects an older identification with the gall of glass. Lethargyrium likewise uses spume language for matter separated in purifying metals. These comparisons show that similar residue words require attention to the subject and the author’s stated distinction.

Places to Read

Anathron. A rock-associated salt described through appearance and disputed identification.

Lethargyrium. A separated scum from the purification of three named metallic materials.
