Abstract
These color television (CTV) panel tint glasses involve using base CTV panel glass compositions with enhanced levels of Ni and Co colorants. The approach uses non-lead CTV panel glass compositions with high levels of Ni and Co oxide as colorant glasses for tinting clear CTV non-lead panel glass. Nickel oxide was varied from 2 to 18%, while cobalt oxide was varied from 0.2 to 2%. A preferred range of compositions with cobalt oxide levels below 1% and nickel oxide levels below 10% was found to be very acceptable for CTV panel colorants.
