The bleaching power of light depends on its actinic or chemical rays, which, like chlorine, appear to act as an oxidising agent.
Most of them depend on the oxidising effect of water when undergoing decomposition through the action of chlorine.
Lead glass should be heated for this purpose in the oxidising flame (pp. 17 to 22).
If they should become blackened, however, the stain may be removed by re-heating in the oxidising flame (see p. 18).
