I. glass, n.1
    (glɑːs, -æ-)
    Forms: 1, 3 glæs, 2–4 gles(e, 4–7 glas, (4–5 glase), glasse, (5 glaas, glasce, 6 glace, glasshe, 9 Sc. glaas), 6– glass.
    [OE. glæs str. neut. (? erron. masc. in Bæda's Eccl. Hist. v. v.) = OS. glas, gles (Du. glas), OHG. glas (MHG. and mod.G. glas):—OTeut. *gláso{supm}; a variant with consonant-ablaut, glazó{supm}, is represented by ON. gler, Da., MSw. glar; the mod. Scandinavian langs. have glas from Ger. (already in MSw. and MDa.).
    A related word is prob. OE. glǽr (masc., if the pl. glæsas ‘succina’ be miswritten for *glǽras) amber, representing the OTeut. word (? *glæ̂zo-, ? *glæ̂zi-) adopted in Latin as glēs(s)um, glæsum. The OHG. glas occurs as a gloss to electrum amber. The ultimate root may be OTeut. glă-, glæ̂- ablaut-variant of glô- to shine: see glow v.]
    I. As a substance.
    1. A substance, in its ordinary forms transparent, lustrous, hard, and brittle, produced by fusing sand (silica) with soda or potash (or both), usually with the addition of one or more other ingredients, esp. lime, alumina, lead oxide.

    II. Something made of glass.
    4. a. A glass vessel or receptacle. Also, the contents of the vessel.
    The specific application as in 5 is now so predominant that the word is now commonly applied only to vessels more or less resembling a drinking glass; a glass bottle or jar, for instance, is no longer called ‘a glass’. But the wider use survives in the collective plurals.
