  3. S Crack.

    Thank you for your replies. Merry Christmas to everyone.
  4. S Crack.

    Can an S crack be repaired with paper clay? I really like the bowl I made and will make others. I'm hitting the "Christmas rush." Thanks for your help..

    Wonderful video, thank you. Brenda
  6. I read the article on kiln wash. Does it need to be bisque fired before using? How do you prevent sifting down of particles during glaze firing? I vacuum kiln proper to use.
  7. So, glaze runs off nail or glaze runs out of the container in so many seconds or glaze covers your hands like cream. Please explain, and thanks.
  8. That's correct so long as you are compensating for the weight of the container. I do it this way. I have even made myself counterweights for my triple beam balance for the containers I use so I don't have to do any Thank you. Thought it was too easy where nothing seems easy.
  9. I don't have a hygrometer and need to calculate the specific gravity of a glaze I am mixing. The glaze is premixed and I wasn't told how much water to add. If I measure 100 ml. In a container and mark the container at that level. Next add some water to glaze and stir well. Then sample the glaze in marked container and weigh. If the weight is 140 gms., isn't the specific gravity 1.40? Thanks for your help.
  10. Thank you for your answers and suggestions. One more question. Why do handles of some mugs get very hot in the microwave after heating for 30 seconds? Happy Thanksgiving to all! BRL
  11. Throw a small cylinder. Do not glaze it. Fire small cylinder. Put small cylinder on a sheet of paper. Fill small cylinder with water. Leave small cylinder over night. Next morning move small cylinder and look very carefully for any sign of dampness on the paper. If there is no dampness then that clay is vitrified at the cone you fired to. If there is even the slightest hint of moisture where the cylinder was on the paper then that clay is not vitrified and you should test further to see if firing it to a higher cone will mature the clay. But, do not make functional pottery out of it and do not think you can stop the leaking with glaze. The answer to your second question is yes if the stoneware matures at cone 6. Jim

  15. How do you know if ^6 stoneware is vitrified? Is it safe to use stoneware to ^6 in oven, coffee mugs, or casserole dishes?
