The elements of experimental chemistry
This oxide, when heated in an open crucible, burns vividly, and is changed into a
yellow powder, which is tungstic acid. Tungstic acid may be reduced to a metallic
state, by heating it intensely with charcoal in the usual manner; but the process ...
When the reduction is attempted in a porcelain crucible, a loss is always
experienced, arising from the oxygen of the stannic acid, which is reduced to
metal, and a third of the oxygen of the tungstic acid, which changes to tungstic
oxide.
