I work in porcelain jewelry and we 50/50 bisque fire/single fire.

It depends on the detail of the work for us.

I have found that doing single fire on highly detailed (fine carving etc) tends to take away from the texture little bit. Also a benefit to doing a bisque fire is that if you mess up your piece while painting it you can simply wash the piece and start over. We do a lot of highly detailed work so it's beneficial to do a bisque for us.

Single firings are great when the piece is less detailed and I just want the glaze to do the talking.

So pros and cons for both.. Just have fun with it!
