Can you glaze fire twice?

Yes, technically you can re-fire ceramics hundreds of times - look at what kiln furniture does, it's clay. As for re-glazing your work, typically this is done from high temp to low temp, you cannot exactly take a low-fire surface and fire it to hotter temps without risking some unwanted effect (or maybe you want it).

Also know, can I Refire a glazed piece?

Since these firings need a lack of oxygen in order for the glazes to develop, you can't refire them in an oxidation firing (electric kiln) or all the reduction you did will be reversed. For example, in Raku, carbon causes the clay to go black where it isn't glazed.

Likewise, can pottery be fired twice? Most pottery is fired twice (or in some cases 3 or more time!). The first firing is called the bisque, then there is a second firing for the glaze. This is the way you probably learned, and they way you probably do it. But it is possible to fire only once.

One may also ask, can you Reglaze already glazed ceramics?

The goal, of course, is to get the new glaze to stick to the old glaze. Spray the piece with spray starch, let dry, then reglaze. Spray the piece with sticky hairspray (usually the cheapest you can find), dry, reglaze. Heat the piece first, with a heat gun or in the oven or kiln.

How soon after glazing can you fire?

Glazing should be done just before loading the kiln, as glazed pieces that lie around gather dust and get damaged. Some glazes tend to crawl if fired right after glazing. If you have such problems, allow the glazed ware time to dry completely before firing.
