If you're bisquing in an electric kiln, try to place the plates toward the top of the kiln where they won't cool down as fast.June Perryhttps://www.blogger.com/profile/13431678118459690271noreply@blogger.comtag:blogger.com,1999:blog-6638497050839732163.post-4426759640112123182009-08-20T09:35:47.631-04:002009-08-20T09:35:47.631-04:00Y'all are so smart!

I busted it to see the cross section and the plate's pretty damn uniform in thickness.<br />This type of crack doesn't always show up at the "V" in the cut af the rim. If it were the "V," I wouldn't think it would crack so far into the plate, but I don't really know anything anyways. <br />Thanks so much for the input!<br />I can always count on you guys ;)Clay Clubhttps://www.blogger.com/profile/12803432318311820987noreply@blogger.comtag:blogger.com,1999:blog-6638497050839732163.post-8728716293705377012009-08-19T18:02:44.240-04:002009-08-19T18:02:44.240-04:00Since it has happened several times... does it alw...Since it has happened several times... does it always come from the "v"?

Another antidote may be to pierce the plate with a fettling knife just below the "v" and see if that stops it. It may not work ??!! But if you were desperate. Another solution may be to cut a "u" shape to not incourage the crack???<br /><br /><br />JohnJohn Britthttps://www.blogger.com/profile/17496106721092541557noreply@blogger.comtag:blogger.com,1999:blog-6638497050839732163.post-15580176182609753972009-08-19T12:44:31.543-04:002009-08-19T12:44:31.543-04:00PS: Sometimes, uneven drying is the problem.

Covering the plate with plastic, but leaving a hole so the center of the plate, can help even out the faster drying rim.June Perryhttps://www.blogger.com/profile/13431678118459690271noreply@blogger.comtag:blogger.com,1999:blog-6638497050839732163.post-33878310395687621242009-08-19T12:21:45.981-04:002009-08-19T12:21:45.981-04:00Emily,

I first noticed that it comes right off the point where you carved in, so I thought maybe you over stressed it there. <br />But June has a good point, and the crack seems to curve into where the thicker foot ring might be. <br />Break one open and look at it--if June's suggestion is correct you should be able to see it.William Bakerhttps://www.blogger.com/profile/09067817926653909848noreply@blogger.comtag:blogger.com,1999:blog-6638497050839732163.post-116281868856887592009-08-19T09:22:52.349-04:002009-08-19T09:22:52.349-04:00Hate when that happens!

You can try making the base thinner, or sitting the base up on a few pieces of bisqued wads, or putting notches in the foot, etc. <br />It may also have something to do with compression during throwing.June Perryhttps://www.blogger.com/profile/13431678118459690271noreply@blogger.com
