  1. I tried the sand and I got the worst cracking ever.
  2. I really like glazes such as lalone crawl and binger that tend to crack and peel off like potato chips when applied over other glazes. I have struggled with different ways to get them to stick on vertical surfaces. I think I finally found something that works. I noticed that when the potato chips would peel off they would have a layer of the underlying glaze on their bottom side. This to me meant that the potato chips were sticking but the underlying glaze was not strong enough to resist their pull. I have found that brushing a couple of thick layers of CMC solution over the underlying glaze and letting it dry until it is still just slightly tacky strengthens it. The potato chip glaze applied over it sticks well to the still slightly tacky CMC without pulling up part of the underlying glaze.
  3. Yep that's the one ... thanks I messaged PDwhite to see what he's up to
  4. If I remember correctly, there was a thread on how to do reduction in an electric kiln by introducing a little propane. I thought I was subscribed to it. I haven't heard from it in a long time and I can't find that thread. If I'm not delusional, can someone point me to that discussion. By the way, I discussed this with Skutt technical support. They thought it was a good strategy to build a bomb
  5. I just dug out a quart of paper clay from the back of my refrigerator. I made it a couple of years ago with wood fiber and a few drops of chlorine bleach. There is not one black spot in it. It smells sweet and is perfectly smooth.
  6. Bar's stuff is truly strange. Also being an art welder makes fabrication of gizmos easier.
  7. Thanks for researching that out for me. I looked at some of her other videos and they were so vacuous I didn't pursue it further, though apparently I should have. I was hoping for some more mechanized approach rather than just manually poking holes.I will have to give that some thought since I'm the gizmo guy
  8. Does anyone know how this texture is made? https://wh25pg4ymc-flywheel.netdna-ssl.com/wp-content/uploads/j-tavill05.jpg
  9. Travill's work is very interesting. Do you know how she makes that texture with a lot of little different size holes?
  10. Preeta What do you mean by "Personally until the science changes i stay away from glass"?
  11. Thanks for the link. That looks good. I will mix some up and give it a shot. Tony Hansen's pretty amazing guy
  12. All of the cone 6, Supposedly clear glazes, that I've mixed up are a milky white when they get very thick. The best I have found is Laguna WC 520 commercial glaze. Does anyone know of a truly clear glaze?
  13. The pots that I posted pictures of in my cracking platters post were destined to have fused glass decoration. I have tried glass by putting a little colored glass in the bottom of a bowl and firing it in a cone six glaze firing. I've gotten some interesting results. I thought it was time to start using a separate cooler glass fusing firing after the glaze firing. Has anyone experimented with this?
  14. They are about 3/8 thick. What would be optimal?
  15. Min The sharp edges are a good observation. Yes, they are very sharp. During bisque firing, would sand, upside down and slow cooling be the answer... Or something else? Are certain kinds of sand better for this? Babs My new standard operation will be flicking platters and pitching if they don't ring true. What's the logic of not firing all platters? How slow should I dry these things?

What's the minimum distance you would have between the edge of a platter in the elements? Callie ... Pres The ultra long drying was an attempt to solve this cracking problem. How slow should I dry these things? Pres talked about a week and 1/2 from throwing to glaze firing?
  17. Thanks for the input. Sand, firing upside down and slower cooling it will be.
  18. No, I have not tried putting sand under the platters. I have been putting five or six 5/16 inch ceramic rods radiating out from the center of the platter. Maybe sand would be better.
  19. I'm having severe cracking problems on large 20 inch platters. I think it's from hairline cracks developing during drying. The platters were dried upside down for about four months inside large plastic bags. Every week or so I would open the end of the bag and flush some fresh air through to clear out some of the condensation on the inside of the bag. Some of the platters were thrown in the traditional pull a cylinder and spread it out technique. Others were made from a slab laid on the bat on the wheel head. It doesn't seem to make any difference which way they were made. Attached are pictures of various styles of cracks. Suggestions please
