Q. What is greenware?A. Greenware is the term given to a molded piece of clay after it is removed from the mold. It is generally grayish in color and extremely fragile. It is not green in color but rather, "not mature", as it has not been fired yet...thus the term "greenware".Q. What temperature should I fire my greenware and/or glaze to? A. Greenware is typically fired at Cone 02 - 05 depending on the type of finish being used. If the piece is going to be glazed then the Cone 02 - 04 temperatures are better. If the piece is going to be decorated with a non-firing product then the Cone 05-06 temperatures are sufficient...however if you are uncertain at the time of bisque firing then it is better to fire to the hotter temperatures (Cone 02 - 04). The non-firing finishes can still be used on the hotter fired bisque but may not absorb as easily into the "harder" bisque. The fired finishes, such as glazes or the "underglazes for bisque" will work better if applied to a bisque that is fired hotter thus allowing you to fire the glaze at a cooler cone (05-06). Q. Are all non-toxic glazes food safe? A. No...not all non-toxic glazes are food safe...when in doubt always check the label on the glaze bottle. Also fire the glaze as instructed on the label for best results. Q. Why does my glaze not want to dry on my piece in just one place? A. This is probably what we call a "hard spot" or "hot spot". It is a problem that is hard to avoid...generally caused during the casting process...but can also be caused by improper cleaning methods. A little white vinegar in the water used for greenware cleaning will usually help resolve the problem...but if the piece is already bisque fired then you will probably have to be careful and let it dry slowly. Q. How long must I leave my slip in my mold before dumping it out and then when can I take the piece out of the mold? A. First of all there is no set time for leaving slip in a mold...however taking various factors into account such as the size of the piece, the quality of the particular mold company, the type of slip, the general condition of the mold (is it wet, dry, old, new), the type of piece (some pieces should be cast heavier than others e.g. cannisters should be heavier that ornaments) all determine the answer to that question. Also enviromental conditions (e.g. humidity) can be a factor. I know at this point I have not answered the question very well because there is no definitive answer. Every mold is different...completely! So the best answer I can give you is to experiment with what works best for you and be willing to change your "time" for each and every mold!
