  1. Silica Sand For Use Under Slabs

    Hi, Thanks for all replies Perkolator, Marcia, etc I think you've just saved me a lot of time and hassle. Julia
  2. Silica Sand For Use Under Slabs

    Hi, Thanks for replies, I'll follow your advice. But do you not get warping if fired on their side? Marcia, what coils do you use? and can they lean at an angle against the bricks? Thanks again. Julia
  3. Hi, I have some large slab pieces approx. 12" x 12". In the past I have had problems when firing ie cracking and explosions. Would using silica sand help and how exactly do I use it? Thanks in advance, Julia
  4. Two Pieces Ruined, Help Needed

    Hi, thanks for going to all that trouble Yes its earthenware and cone 2. It does have a controller so I will attempt to reprogramme to your recommendations and see if its any better. Its hard not to peek but I'll go walk next doors dog ! Thanks again, Julia
  5. Two Pieces Ruined, Help Needed

    Thanks Min, Wow I really thought they were dry, I did the moisture test with my finger and they seemed ok, but I guess not I fire to 1140 °over approx. 12hrs about 100°an hour with a half hour soak. I don't open the door until its under 200°and even then just for a peek. I also never used to cover while drying as It takes so long anyway but will start doing this now. I have to confess these two pieces were left out in the rare sunshine for an hour or two just t speed it up so I suppose that didn't help matters.
  6. Two Pieces Ruined, Help Needed

    Hi, these are the pieces after I took them from the kiln. Pic 2 seems to have just cracked straight across with the attached pieces coming away from the surface. In the first one the piece has seemingly crumbled in one part as well as the smaller pieces coming away from the surface, very curious as to what has caused the crumbling. Any ideas very welcome. Julia
  7. Two Pieces Ruined, Help Needed

    Thanks for replies it was a bisque firing and yes gravity was on my side. Unfortunatley the pieces are broken and unable to glue with glaze. Marcia I might have a photo later. Julia
  8. Hi everyone, so Ive just opened the kiln and its not good. I had two large tile pieces which smaller pieces attached on by scoring , slipping wiggling and pressing down really well. Or so I thought the smaller 'attached' pieces have come away from the surface tile making them only fit for the ceramic grave yard. Ive made a piece similar before and Is been fine and the thing is I have three more pieces ready be fired. Can anyone shed any light as to why this is happening? Im certain they are dry and I took extra care in fixing them on, all help much appreciated. Julia
  9. Hi everyone, I accidentally fired earthenware clay to 1300°, oops. Its all stuck to the kiln bats and I need help in how to clean it all up. There is also one piece fused to a kiln brick. Its a big mess and a lot of work lost. I would really appreciate any help on this. thanks Julia
  10. Hhi everyone , I hope someone can help with this question. I am making pieces for the garden and so using stoneware and high bisque firing. However the glazes I want to use are firing around 1040, really bright colours. Will the fact that its an earthenware glaze on stoneware be a problem, ie will it fire to the correct colour? Thanks Julia

  12. Help With Oxide Colour

  13. Amaco Chalks?

    thanks for all your help everybody, I may try to make my own with the Mason stains although I hate the technical stuff. I found them in 'the big ceramic store' but unclear if they ship to Ireland .
  14. Amaco Chalks?

    Hi all, I hope someone can help with this. I came across some work by a potter who said she used chalks over slip to draw on bisque. I can't remember her name but her work was beautiful. Im trying o find these chalks myself, does anyone have any experience of using them and any other info about them. I have tried the crayons which were useless as was the pencils. I cant find them in my usual supplier (Ireland) or the UK. Thanks Julia
