What a great idea. I love it.

That is indeed awesome.
You don't have any pictures of the mugs do you?
I attached an image of the mug and also the formation I dug the clay from. The thin whiten layer in the center is the debris left from the meteor impact. Not much to dig from but then I only made about a dozen mugs. The mug does look a little rough, like the formation. I was tempted to cute it up a little, but decided to leave it alone.
The geologists though it was great. One of them wanted me to start production, or at least make a dozen more for everyone in his department, but I declined.
I never realized the K-T layer was so much lighter than the layers under and above it. Obviously, the small amount of iridium there wouldn't cause this, what did?
BTW, the mug is cool.

In Topic: Second bisque firing
Posted 18 Jun 2013
If the pots are DRY and they are not extra thick (like in sculpture), then you're just wasting time and electricity by looking at mirrors and worrying about the chemical water. Just fire with lid closed and all peeps in (or leave the top one out for the whole firing) on low until you are well past boiling say 250 degrees F. then turn the kiln on high. That's the "schedule" I've always used and use now in 3 different elect kilns (each a different size and manufacturer) to bisque and my pots don't blow up. Basically, what Marcia said except I probably turn on high after about 2 1/2 to 3 hrs instead of 4 depending on how full the kiln is and how big the biggest pot is.

In Topic: Steven Hill's Firing Schedule For Bisque?

clay lover, on 17 June 2013 - 08:43 AM, said:Thanks for the dipping suggestions, OC. I will get into trying these glazes again this summer. I mixed several of them after taking a workshop with SH about a year ago. I will make beefier test tiles and have another go. SH says SCM should be 60% of the total glaze thickness, so I was operating off that. My spraying tests worked well, just would like a more efficient way to try lots of combos.
It's good to know others that are working with these glazes, hope we can continue to support each other's efforts. There is a web group about this, but it seems dead and is very difficult to navigate.
John, thanks for the pictures, nice results.
Obviously, Steven Hill knows more about his glazes and techniques than I do, but when SCM is thicker than the glaze over it (in my case often Juicy Fruit) I tend to get a muddy yellowish color. When I reverse it and the SCM is thinner than the glaze or glazes over it, I get better reds and golds. I guess it depends on the glazes, and only tests will determine what works.

Jim could make moth balls. Oh wait, that's a different thread.
I don't know. Do you really want someone finishing off a drink to see a frog or a moth's balls in the bottom of his/her cup?
