A piece should typically dry for at least 24 to 48 hours before bisque firing, depending on its size and thickness. It's important to ensure that the clay is bone dry to prevent cracking or exploding in the kiln. You can check for dryness by feeling the surface; it should be cool to the touch and no longer feel damp. Proper drying is crucial for a successful bisque firing.

What is bisqueware?
Ceramic bisque is undecorated fired ceramic. In ceramics, there are usually two firings in order to finish a piece. The first firing produces a piece that is hard and able to be decorated with ceramic paint. The second firing makes the paint melt into the waterproof coating that is glass like in texture. So bisque is the first firing. This piece can be decorated with paint that does not need to be fired the second time. These pieces are very common in decorative figurines.
Why do you bisque fire your work?
Bisque firing is essential because it removes moisture from the clay, making it more durable and easier to handle during glazing. This initial firing also helps to eliminate any organic materials that might cause issues later in the glazing process. Additionally, bisque firing allows for better adhesion of glazes, resulting in a more vibrant finish and preventing glaze defects such as crawling or blistering. Overall, it enhances the final quality of the ceramic piece.
What would happen if a salt wash was applied to bisque and then fired?
You'd have a salt reaction with the clay body and depending on firing temp achieve a salt fired piece...
What is the difference between bisque and glaze firing?
Bisque means it has been fired once, removing chemically bound water and also allowing the clay body to vitrify. Glaze fire means it has been fired a second time with glaze on the object. Some industrial methods can fire glazeware in one fire, however this is uncommon to the hobby world
How 2 prepared a bisque?
Bisque is the general term for any unglazed clay that has been fired. In high fire pottery a piece is generally fired without glaze at a lower temperature and then glazed and fired at a higher temperature.
What does biscuit fired mean?
"Biscuit fired" refers to a specific firing process used in ceramics, where clay objects are heated in a kiln at a low temperature to remove moisture and harden them before glazing. This initial firing, known as bisque firing, prepares the ceramics for subsequent glazing and firing at higher temperatures. The term "biscuit" originates from the French word "bisque," meaning unglazed ceramic. The result is a porous, yet sturdy piece that can absorb glaze effectively.

Can you glaze greenware fired to the wrong cone?
Glazing greenware that has been fired to the wrong cone is generally not advisable. Greenware, which is unfired clay, can only be glazed before it undergoes its initial bisque firing. If the piece has already been fired incorrectly, it may not be able to withstand the glazing process or the subsequent glaze firing, potentially leading to cracks or breaks. It’s best to start with properly fired bisque ware for glazing.

What is the difference between stoneware and ceramic?
http://stoneware.seeleys.com/html/what_is_stoneware.htmlDifferences in an undecorated piece of stoneware and earthenware: Stoneware Impervious to water (water tight) Chip resistant Color: Buff or terra cotta Feel: textured Look: like pottery Looks great undecorated or decorated. Can withstand high/low temp. Oven safe Suited for household use. Painting bisque: Wipe off mistakes. Glazes flow: bisque is not porous Firing: Leave the bottom of the piece dry and place on shelf Earthenware (ceramic ware) Not impervious to water (cannot hold water) Chips easily Color: white Feel: chalky Look: rough white Can only use when decorated. Cannot withstand high/low temp. Not oven safe Suited for decorative use Painting bisque: Cannot correct mistakesGlazes adheres to bisque: bisque is porous Paint or glaze the bottom of the piece and stilt on shelf.

Where do you place a piece of pottery when it is being fired?
When pottery is being fired it is placed inside a kiln. Most potters do two firings, one for bisqueware and a glaze firing. Bisqueware is pottery that has been fired to a temperature hot enough to not only evaporate any water in the clay, but also evaporate water at the molecular level thus changing the chemical structure of the clay molecules and creating the hard material you know as ceramic. After bisque firing, pottery is glazed and placed in another kiln. There are many types of glaze firings. Some are done with gas (reduction firing) and some firings are done with electric (oxidation firing). There are also unconventional methods of firing such as Raku, pit firing, and soda firing.

What would cause a piece to explode in the glaze firing if the piece was bisqued before glazing it.?
There are a few things that can cause raku to explode in the kiln. One is firing the pieces at too high a heat too quickly. Some types of clay also fire better than others. In raku, course or groggy clays seem to hold together better than the denser or finer clays. Other culprits may be glazes that are not dry, or placement. The pieces should be placed so that the flame is not directly hitting them.
