Q: Can you bisque fire this at cone 04?

1. UPSALA – Can you bisque fire this at cone 04? The recommended bisque firing temperature according to our technical recommendations on our website is 1000ºC which is equivalent to cone 06 (1855ºF). Nevertheless, a bisque firing up to cone 04 is still ok, especially for our porcelains and stoneware. It’s important to know that with higher bisque firing temperatures, the object becomes harder and less porous, but it might be more difficult to apply the glazes as the liquid cannot easily enter the pores.
