  1. Cracked Bottom Help

    SILLY ME. Yes, I meant mm, not cm. That's what I get for replying at 11pm. Also, yes, I know not to leave water at the bottom while throwing. Gee, could you imagine if my walls were 2 cm thicker than my bottoms? Either the bottoms would be paper thin or I would have some ridiculously heavy pottery...

    Interesting. what wire do you use?
  3. Cracked Bottom Help

    I cracked them open. The bottoms are thinner, but not very much so. I'd say the difference is less than 2cm. Nevertheless I will endeavor to make them more uniform in the future. I will also try the newspaper trick as well. Thank you for your ideas.
  4. Cracked Bottom Help

    I know all of this. Which is why I've always been good about compressing the bottoms (with a wooden rib). It still doesn't make sense that these are the only things that are cracking. Also I do "work" the bottoms. Usually I push in so it doesn't rock, then run a finger over the bottom to smooth out lines. After it comes out of the bisque kiln, I sand it to get anything that might have gotten on during the drying process off. If this were simply an S-Crack situation, then why aren't my wine chillers - which are just as wide, or my brie bakers, which are wider, not cracking? I throw on wooden bats, then when they're dry enough to come off the bat I transfer them to unfinished wooden shelves, still right-side up. Wouldn't having the bottom against the wood surface (thus keeping less air from hitting the bottom) make the bottoms dry slower than the sides?

    Yes, the bottom of the basin. So, if I were to turn these upside-down as soon as they are stiff enough to manage it, would that also help? that would help them dry at a more similar rate, right?

    Here you go. The 4th one broke down the middle when I threw them out the first time, but here are the other 3 one two three
  7. Hi guys, I was hoping you could help me out. Just recently, I finished a bisque load that included 4 dip chillers. These are the types with the large basin bottom (for ice) and the bowl that sits on top (for dip). For some reason, every single dip chiller has cracked. I don't understand it. Neither of my other wide-bottomed pieces cracked -- I had 2 wine chillers and 6 wide bowls. And I'm always careful about compressing bottoms. They were on different shelves in the kiln, and I brought everything in at the same time. For some reason dip chillers have been a large problem for me in the past, too. I'd say about a third of the ones I make crack. To try and combat this, I no longer store the small bowls on on them while drying or during firing (I fire them separately for both bisque and glaze firings). I am just so frustrated. Does anyone have any ideas as to why these are so prone to cracking?
