Abstract: A copper oxide containing seal glass is formed by a controlled low temperature process which reduces the formation of seeds in the glass. In one embodiment the glass is prepared in two portions with the first portion containing the high melting oxides and the second portion containing the low melting oxides. The copper oxide is added to the second portion and the two portions are combined to form the seal glass at temperatures below about 800 DEG C which reduces the formation of Cu2O crystals in the glass.
