How Can Antimony Trioxide Take the Bubbles Out of Glass?
There are many ingredients that go into making glass at different points in the glass making process. Fining agents are an important part of glass manufacturing. These additives are included with other ingredients during the meltdown phase of the operation. If you did not add a fining agent, small pockets of undissolved gas bubbles would remain in the glass. Bubbles have a negative impact on appearance and mechanical properties of the final product. Nobody wants to see a wine glass with bubbles in it unless it is intentional. Antimony trioxide is a very common example of a fining agent. Its presence causes smaller bubbles to come together and form larger bubbles. The larger bubbles are then able to rise to the surface of the molten glass. The result is a bubble-free mixture of fluid glass.
