Opal glass shades have been produced in considerable quantities in the Birmingham and Stourbridge districts, but depression in the trade has caused several of the works to be shut down, and output is, for the time being, on a very small scale. It is not possible to indicate the number of hands employed on this type of product, as the character of the production in many glassworks is subject to constant change. No records are available from which the annual output of this restricted class of goods could be stated.
