Hello,
I am creating a large scuplture built in 19" by 11" sections. I am using 240G standard clay and firing at cone 6. I am now aware this clay body is not a good choice for this sculpture but have a deadline in 2 weeks and have to push on through. With the intent to find a better clay body for the next one. With all that being said I just unloaded a glaze kiln to find the piece totally cracked in half. It had no cracks when it came out of the bisque kiln. Do you have any suggestions on ways to avoid this when I remake this piece? I have attached images.
Thanks,
Sarah
