Bisque Firing is the easiest way to make your object be completed quickly. When you make a ceramic piece, it is using wet clay that has a water content which needs to leave the clay body in time for the hot firing processes that help glaze connect to clay. Bisque Firing is the 3 day firing that forces all the water (everything form regular water, intra-mollecular and more) to leave the object and transform the clay into (almost) stone.
A bisque fired piece is porous, like a fresh prawn cracker at your favourite Chinese restaurant, and those pores are what help the liquid glaze be carried into the heart of the object, making a strong ex-skeleton of glaze.
If you don't want to bisque fire, thats cool, but it carries similar risks as to firing solid objects (above), thus it is important for the technician to know! Please give them the heads up before booking into a specific firing as depending upon the size of the object you may be better off in your own Friday Freestyle firing, and the tech will know what to recommend. .
This is called "once firing" and can be an interesting way to encourage thin-glazed-clay objects to flop a bit during firing. This happens because there is still water in the clay body and then more water added when glaze is applied, mixing it all together and making a type of glazy clay.
