The Potter's Dictionary of Materials and Techniques
See In glazes barium carbonate is used because it is relatively insoluble
whereas the desired barium oxide reacts with water. It is intended that, during
firing, the carbonate decomposes to become the required barium oxide and
carbon dioxide ...

The Complete Guide to High-Fire Glazes
It's sometimes used to provide a less toxic form of barium oxide in glazes and
clay bodies (as in Wedgwood's Jasperware), but it does release sulfur fumes
when fired. Soluble sources of barium oxide are barium carbonate (almost
insoluble), ...

A Comprehensive Treatise on Inorganic and Theoretical Chemistry
When barium oxide — BaO is heated in air to about 500°, it is rapidly oxidized to
barium dioxide : 2BaO+02 =2Ba02. If the barium dioxide be heated to a still
higher temperature, 800°, the oxygen is given off and barium oxide remains as a

electron emission and adsorption phenomena
The barium adsorbed upon the surface and in the lattice of the barium oxide must
either be introduced from an outside source, or it must be formed from the barium
oxide itself. In the method mentioned in § 100, where the oxide-coated filament ...
