Abstract
A television face plate resistant to browning is formed by melting and refining molten glass which contains cerium oxide as an anti-browning agent, the process being carried out in the presence of a sulphur containing compound such that the cerium oxide is converted substantially into the cerous state during melting and refining thereby increasing resistance to browning.
