The furnace used for the production of optical glass is generally constructed to take one crucible only, so that the heat of the furnace may be accurately adjusted to the requirements of the particular glass under treatment.
In the latter case the crucible, which was placed in the cavity immediately beneath the arc, was about 3 in.
