Most glazes contain toxic materials before they are fired. That is why it is best to use a mask when spraying and to not eat around liquid glazes. Once the glazes are fired however, they are no longer dangerous with the exception of glazes that contain lead frit. These are usually labelled "not for use with food".

How many coats of glaze do you need?
The answer to your question depends on what you want your final product to be. If you intend on having a gold or silver glaze on your ceramics, you have to go through several steps.

After fired, you will then be able to paint on the next coat, whether it be another coat of glaze or your silver or gold glaze. You can have several layers of glaze on an item, but there could be chemical interactions depending on colors and composition of your item.
