  1. Ceramic Question For A Project

    Maybe line with this castable refractory: Probably your best bet http://www.sheffield-pottery.com/LOUCAST-3000-CASTABLE-MORTAR-p/lvclc.htm
  2. How Often To Change Filter In Mask?

    Manufacturer of North Respirators recommends changing after 8 hours of use !
  3. Gas Vs. Electric- An Alternative View

    Have heard anecdotal evidence of this.... Thanks JB for knowing that it's correct and also why ! .... you are the best!
  4. Albany Slip Sub

    The Sheffield one is darn close to perfect. Not that far from albany, didn't take much modification of the natural clay there to make it almost identical empirically and physically http://www.sheffield-pottery.com/ALBANY-SLIP-SUBSTITUTE-by-the-pound-p/rmalbsub.htm
  5. The 2 different 110 plugs indicate different amperage on the circuit and also should indicate the wiring in the wall as well. The standard household outlet is for 15 amps max. Very few kilns can run on such a small amount of amperage. Household voltage kilns usually need a 20 amp breaker and circuit. Don't just change the 15 amp outlet to the 20 amp outlet willy-nilly : the wiring from the panel to that outlet may only accommodate 15 amps max. By pulling more amps than the wire can handle you are asking for trouble, like big trouble, like a fire.
  6. Sheffield Black is cool and dark as heck It's c05 Low-fire earthenware http://www.sheffield-pottery.com/BLACK-MOIST-EARTHENWARE-POTTERY-CLAY-p/mc94600.htm
  7. High Temperature Kiln Rods

    This one works: much thicker http://www.sheffield-pottery.com/CERAMIC-BEAD-BAR-p/kcbbh.htm
  8. In addition to the kiln god figure to create, there are some traditional offerings to make, lamb, bamboo, colored paper etc. 31295017115808.pdf - Repositories
  9. Amber Glaze

    Cowan amber Celadon in John Britt's Complete Guide to High fire glazes is lovely: Sometimes does crazy fantastic blue hares fur when pummeled with wood ash for days on end too! (that's it doing that in my profile picture). Although the back side away from the ash stays that honey amber. 44 custer 12.8 silica 17.7 whiting 6.1 ball clay 11.1 redart 2 bone ash 3.8 talc 2.5 g. borate 4.1 RIO
  10. Vent Not Turned On During Bisque

    The vent is for the wares and the potter but since the clay is now sintered, rebisque fire will not get any more of the potential problems out; once sintered, the clay cannot release those gasses until near top temp when the clay is as close to molten as it gets.
  11. Clay For Sculpting Vs Throwing

    Hi Rebeka : It reallly is all about the grog content: otherwise no big difference. Some sculpture bodies, especially for those who make super large things may have Kyanite as well which is an odd material that actually gets bigger not smaller when fired. The grog (and Kyanite) is really about restricting cracking that can happen with a thick thing from shrinkage. But in general, take your favorite stoneware or eathenware, add 10-15% grog and there is your sculpture clay
  12. Manual Sitter Vs Digital Controller; Your Preference?

    Bailey kilns are nice nice : they are Cone Arts wearing a Bailey t-shirt
  13. no point in slowing in the glaze fire: the clay is sintered so gasses cannot escape. Do a hold in the bisque fire at about 1500 (sintering starts at 1600) for 2 hours ideally. Loose stack for the bisque, don't tumble stack the dark clays
  14. Bubbles In Salt Buff Glaze

    Sharp little volcano bubbles come from either cooling to quickly or from overfiring the glaze.
  15. Some wheels are available in 220 euro voltage but some are not. Plug adapter will not do it for sure! : you need a voltage converter to 120. They are not very expensive (Maybe around $75)
