Why use slow bisque over fast bisque? Is it just a moisture issue?
- Slow bisque is the safest to use and ensures a better firing to get out fumes and water vapors.
- The more carbonaceous materials you oxidize during the bisque firing the less potential you have for outgassing during your glaze which will cause pitting in your glazes.
- For very thin work or for certain clays you can use the Fast Bisque - or if it just works fine for you. Start with Slow Bisque and experiment later.
- Remember: Heat-work is always a function of time and temperature. You achieve the same cone firing if you fire slower for a longer time to a lower temperature.
- See this post for an even slower bisque program to use if the standard SLOW BISQUE Easy-Fire program does not work for you.
