  1. Hi Meredith! Congrats on your new kiln. The Vulcan black, does it require an 06 bisque and mature at cone 5/6? That's what I'm seeing here Vulcan Black Stoneware (Fine) 1200-1240C (potclays.co.uk) Note, cone values begin (at the low end) 022, and ascend in temperature to cone 01, then continue to cone 13. Typical stoneware bisque is around cone 06 to 04, then glaze is cone 5 to 6. Take a long look at a chart, e.g. Celsius Cone Chart (clay-planet.com) Black clays can be difficult! First, long slow bisque, with lots of oxygen is necessary to burn off some/most of the gunk ("
  2. One and a half thousandths thick, and sticks too! Please post back your results Lee.
  3. ok - shouldn't there be wear marks when said rod slides to and fro? ...oh, aye, accommodating as the angle flattens, right. Drive ring replacement, adjustment Microsoft Word - Replacing Drive Rings.docx (cromartiehobbycraft.co.uk) Is the rubber ring worn down to the point that the cone is rubbing on the wheel?

  4. Are there two pics Jen? The blue rod that's attached to the pedal moves the motor+cone relative to the drive wheel? Likely Neil is on to somewhat here - the connection pedal to rod appears wonky (also looks like there's been attempts to ameliorate same).
  5. With patience and attention, prescribed firing schedule may be achieved with a manual kiln, however, a pyrometer is almost required - I say "almost" because there are those who can judge temperature by color and possess lots of experience with their kiln/process/ware. I watch my pyrometer, flip switches, and take notes. Let me add here that I have adequate venting and safety gear.
  6. Hi Haddie, There have been several kilns listed on Government Surplus Auctions - govdeals.com in the last month - might be worth watching. Check Facebook marketplace, Craigslist, local ceramic supply bulletin boards, this forum... good luck! There's an Evenheat listed in Glendale Heights, appears to be in good condition (FB).
  7. On inside crazing, am seeing so many cases where ware is crazing on the inside when same glaze is on outside (as well as different glaze on the outside), and no crazing on the outside (also less crazing on the outside). I have theory, will test. I get what you're saying about usage Bill, I'm saying right out the kiln and within the next week or so, no usage. I do so love my hot coffee, aye! Rox, the numeric coe value of your glazes can be helpful, so can the coe of your clay, however, not all clay suppliers test for and publish coe, and, as you are seeing, commercial glazes aren't always
  8. I'd like to think a well fitting glaze (well fitted to a particular clay) allows some leeway in glaze thickness? A glaze that's close to a fit doesn't craze at all on the single dip portion of a test tile, but shows a few craze lines on the double dipped part after a few days, and perhaps about the same on the ware - some pieces show a few lines after a few days, most exhibit at least some crazing it time, and sensitive to a bit thick, where a good fit doesn't show any crazing on test tiles, particularly the double dipped portion, nor anywhere on the ware, excepting, perhaps, a very thick
  9. My small studio triples as a bike shop an' general workshop. I'd choose cycling over bat-mobiling, but I always did like Marvel over DC.
  10. Thanks for the write up! Great on the insulation, efficiency, wow. Maybe set up your bike shop where the batmobile would go...
  11. Fractal burning - one o' those activities that many back away from as quickly as safely possible. See mocha diffusion as another similar effect, somewhat safer category o' decoration. Ah
  12. Is that Michael Casson on th' cover of early edition The Potter's Dictionary of Materials and Techniques? I'm paging through my copy of Peterson's The Craft and Art of Clay again - lots of pictures and ideas in there. Her treatment of unity is the best (my opinion). I'm also looking at the Studio Potter magazine that Mark posted a link to (Summer/Fall 2008 - Thurston's article, in particular - will turn through alla pages tho', eventually), and since that's fun, will pick up where I left off paging through the dozen Ceramics Monthly .pdf files I've tucked away ...the oldest Oct65, ne
  13. ok! Esteem I hold for others' work has less to do with intended use than ...many other things. That said, soon, I'll be inna my fourth year of potting; looking back on the arc o' my progress, I anticipate another load of planters . Ware that have a nick, pit, crack, craze, crater, bloat, and/or don' look right (to me) get a hole drilled in them; I mix up some o' the sand with Kellogg's, wander about the yard gathering succulent cuttings, assemble, then tend'm for a several weeks until well rooted. From there, a few sell, some are given away, and the rest donated to a few outfits 'round he
  14. Hi Luu! Watch Craigslist, FB Marketplace, local clay supplier and studio bulletin boards, government auctions*, local classifieds, etc. - you may find a bargain; cast your net wide to get a feel for the market. Likely you'll find that many listings are overpriced ...might take a while to find somewhat. There's a Brent in Burtonsville, four hundred (FB), which may be reasonable, given it's sound - or doesn't need any major repair... There's a Bailey in Brookfield this a.m. for seven hundred, which may be reasonable if the unit is truly in "like new" condition (try "pottery wheel"
  15. Functional ware is liner glazed by definition (imo).
