  1. Also, do not get the piece to be refired wet!! Sometimes moisture gets into the body and comes out explosively when heated quickly, as one might do with a refire. If it has gotten wet, place in an oven at the lowest possible temperature for several hours, or heat your refiring kiln very slowly.
  2. The gold lustre may look expensive, but its mixed with oil to brush on neatly and a little goes a long way. Fire to 1800F, very low.
  3. Yay! When the clay dries completely in the mold, it will shrink (all clay does, from wet to dry) and can sometimes get hung up where it wouldn't if were only just dry enough to remove. If you do it again, open the mold sooner.
  4. If your mold is white, it's probably made of plaster. Clay poured into a small (under 12") plaster mold, and then poured out after a few or several minutes, will usually be dry enough to remove after a few hours. If you open it by removing the bands and separating the plaster parts, the piece should be dry enough to take out without distortion. If you leave it in for a longer time, it will still probably come out fine When you poured liquid clay (slip) into the mold, did you let it set for a period of time and then empty out the extra slip? If not, you will have made a very solid piece instead of a thin-walled piece. If you just pressed a piece of clay into a one-piece mold, it can be removed as soon as the clay has firmed up enough to keep its shape.
  5. Unless it's in an index, how would I know that solid state relay is SSR? Or vice versa? Just askin'
  6. Does that mean it won't be changed to be perfectly clear to all, even we uninitiated?
  7. Undercut is when the lines of the piece curve inward in a way that prevents the piece from dropping out freely from the mold. Everywhere there is an undercut, there should be a division in the mold so that each piece can be removed without damaging the form. A commercial mold will have been designed to accommodate undercuts. Homemade molds can be learning experiences.
  8. ...leaving a fine coating of alumina, which can be brushed or washed off after firing. A sufficient coating of alumina is what prevents sticking.
  9. Sit, and hold the pot over your lap. Tap evenly around the pot near to the lid. Do not tap on the thinnest parts of the pot. If you're not successful, leave the pot for a few days and try again. Sometimes pouring hot water over it can help. Sometimes it lets go itself after a few years....
  10. From The New York Times:Mercury Is in Retrograde. Don’t Be Alarmed.Scientists will tell you it’s all an optical illusion and superstition. And even astrologers say it’s nothing to worry too much about.https://www.nytimes.com/2019/03/14/style/mercury-retrograde-facts.html
  11. Thanks, Mark. Looks like what we used to call Stoney, but with more variation. I'll compare formulas....
  12. @Pres, do you take the casters off the chair? I don't think I could throw sitting on a chair that wants to roll.
  13. Hi, Doc! I'm thinking that just because these platters are intended for the wall, you are not giving enough love to their backsides. As Neil said, there's a lot of movement going on in such a wide form. Additional trimming on the back, even if you don't trim a footring, could help prevent the cracks you're getting by adding a little compression to the only (but large, area-wise) part of the piece that isn't compressed from both sides. I dry large flat-ish forms on slats for good air circulation, my slat shelf is a repurposed baby crib side (the part that lowers).
  14. Maybe related to the string of cup/mug firing disasters some of our potters have reported lately??
  15. @Mark C., got an example of Mamo Wamo? Not a glaze I've heard of - Stoneware? and, of course, what's in it??
  16. Well, Louise did try other colors :/ For potters, though, barring deliberate constraints like glazenerd's or economic/local restrictions, probably very few potters find a favorite glaze and never change it, never look for variety. It would have to be a very successful formula for them. Sometimes even when we don't want to change, we must, as when Kingman Spar was no longer available. Changing locations/kilns can sometimes mess with a glaze too. Even when I still had Kingman, we could never get Stoneware Yellow in my home kiln.
  17. To respond to the question, any potter who still has their curiosity will eye new glazes and wonder.....
  18. Sounds like fun, @Mark C.! The old redwood and mahogany are treasures. I love the Toto I got for my tenant - nickname: Big Gulp!
  19. Yikes! It's probably gone past leather hard by now! If it doesn't drop out easily, there is a chance that there's problems with the mold design - this is assuming the mold is not a commercial one. Can the OP post a photo?
  20. It looks like the colors are applied by pouring and trailing. Brushing would disrupt the glaze beneath.
  21. @keith barber, your fairly thorough elaborate calculations remind me of the efforts to monetize all the work done by a typical wife and mother, usually neglecting to deduct room and board, haha. We do it because we love it. The more we love it, the more it shows and the better it pays, imho.
  22. @LeeU, love my Bag Balm Never thought of using it as a release!
  23. And how about that pot that throws itself??? Also, the apparent drips of throwing slip that weren't obsessively cleaned off made nice surface interest.
