Bisque firing pottery is a pretty simple process; however, I don't think I could explain how to bisque fire pottery as well as this article on about.com
Be careful when removing the earrings from the kiln! Unless you know the kiln has completely cooled down, you run the potential risk of burning yourself. You do *not*
want to know what it's like to get burned by hot pottery.
Once the earrings have gone through the first bisque firing, you can move on to applying the overglaze to the earrings.
