  1. Using this method, the structure would have to be large enough that blowing rain or snow couldn't reach the kiln. If a storm blows in while the kiln is hot, you can't cover it with the tarp. You're also likely to trap moisture and get a lot of bugs and critters making their home under the tarp. My general rule of thumb is if you wouldn't leave your laptop there, you shouldn't leave your kiln there. Do you guys have bugs in the States? My buddy Alan has a big wood kiln. we fire it in the winter, and usually put up tarp walls to cut the wind. My electric kiln is located inside my studio. Vented, of course. TJR.
  2. You could just have a roof with metal.No walls. When you are not firing you cover your kiln with a tarp. TJR.
  3. We covered this topic a while back. There are many surfaces that people use. Only about 50% wedge on plaster. I wedge on canvas covered plywood screwed to a table top. It's been 26 years plus with the same piece of canvas. I have a one inch square hole wore in it. I just work around it. Might change the canvas when I turn 90. Other surfaces; Slate, marble, plywood without canvas. TJR.
  4. Celia; It's the combination of vinegar and your clay body, with the syrup as stickiness to hold it all together until the crack sets. you could use any syruppy, sticky thing-even molasses. T.
  5. Celia; you are over thinking this. It is just some cheap syrup to make the spooze sticky. you could even make it with sugar water. TJR.
  6. Had my ghetto blaster tuned to CBC radio 2. Alternative rock and indie rock. Because i never changed the station, dust has attacked it and now i can't gey anything. [This was explained to me by a woman customer at my last studio sale]. it's amazing what some people know that i don't know! My other radio is tuned to CBC1, but many times it is lots of talking. I also have an IPAD with a docking station, but I am tired of my play list. I mainly listen to the Stones, Stevie Ray Vaughn, Arcade Fire, Leonard Cohen, Bob Dylan, Eric Clapton,et al. TJR.
  7. MMB; Looks great! Is there any way that you can adjust the primary air with this baby, or do you just blast away! TJR.
  8. Man, you are OLD!Back in art school, we had an electric kiln that didn't even have dials. Each element was turned by a separate switch, like a light switch. My prof said that this kiln design would never fail or breakdown as it was a simple design. Twenty years later, I saw that kiln, for sale, used at my clay supplier. Would have bought it, but I didn't need another kiln. All it had were the switches and a mechanical kiln sitter. TJR.
  9. Don't we just go by the seat of our pants? Chris is being too methodical. Logical. TJR.
  10. Firing too fast. I put my kilns on low for 2 hours, then medium for an hour then all switches on high. Your rate of temperature climb should be 100 degrees per hour. Should take 8 hours to fire a bisque give or take. Is she using a computerized kiln? Maybe adjust the rate of climb. Funny that the recycled clay didn't explode and the new stuff did. TJR.
  11. only certain glazes will work for brushing. The glaze has to be harder and not powdery. I add 3% bentonite to my glazes to make them harder. Some glazes I just cannot use for brush decoration-they either flow too much when fired, or they are powdery when dry. TJR.
  12. My work tables in my studio are counter top height-that is 40 inches. You wedging table should be lower. Your arms should be able to extend out straight for wedging. Your are using your back, not your elbows. TJR.
  13. Hi TJR The advice around a brick reduction chamber is very sound, in fact I received very similar advice from my father who although has a different core medium (casts bronze sculpture through the lost wax process) feels that I could use fire brick to increase the size of both my kiln and my reduction chamber. And because I am using a 500,000 BTU torch I should still be able to reach upwards of 1850F given the correct exhaust size. Taking on a project like that would be very exciting and I would love the learning I would get, but my backyard is also a playground for my children and the permeancy and real estate required for a brick kiln or reduction chamber would more than my lovely wife would be willing to give. Great ideas are fantastic. All advice I get I very much appreciate as I work somewhat in a vacuum, and I haven’t really done ceramics since I left college 25 or so years ago. Thank you again! Ian Ian; Here's a couple tips for increasing the size of your combustion chamber; 1. Build a layer of cinder block for the kiln to rest on. 2.Build a softbrick floor-2 to 3 layers, with one hard brick target brick to aim your burner at. 3.Fill in the big hole in the side of your kiln with fiberfax. Back in the day, we got a grant to travel around rural Manitoba teaching art to country students. We had 6 of us in a van, one art history person, one drawing, one dance, a coordinator, and two raku potters. We could tear down our kiln in 45 minutes from red heat. It was a blast. It was the 70's. TJR.
  14. Been thinking about this quite a bit myself. I was in a sale called Northern Lights. It was a 2 day sale where I have my cottage on Lake Winnipeg. I used to set up the day before for a 2 day sale. The sale was 10:00 a.m. to 5:00 pm for Saturday and Sunday. My problem; the sale was reduced to one day. I was not staying at my cottage. I would have had to drive one and a half hours to the sale. Leave the city at 5:00 a.m. Three hours to set up from 7:30 a.m. to 10:00 a.m. Sit there til 5:00, unpack, load car, drive an hour and a half home. I probably would have made $500.00. Booth fee $50.00. Since I started selling out of my studio, 2 days on Mothers' Day weekend and two days in November for Christmas, I have not been that hungry for selling my work at these small sales. Because I work full time, I cannot do these four day sales. TJR.
  15. Hey, Ian; Looking good! A couple of suggestions; 1.Use a small broken kiln shelf on the flue exit. That way you get a bit of back pressure and not all of your heat is lost out of the flue. 2. Build yourself a reduction box out of brick, or metal-not so tall, with a sheet of metal for a lid. If you are firing in the fall-you can use leaves that your neighbours have bagged up. Nice looking tiles. I used to make Group of Seven landscape tiles with my students. Have you heard of Tom Thompson? Just kidding. TJR.
  16. Do not push the clay out. Keep the rim as narrow as possible, then the cylinder will rise.Way easier to widen out the piece later. TJR.
  17. Giselle; Buck up! Wrong venue for your work. Show was too short. You were undercut by the $12.00 mug guy. Keep looking. I like the two day sale myself. This gives people the chance to tire kick and then return with wads of cash. TJR.
  18. Joel; I always think of a stoneware kiln as firing at the temperature the earth was created. 2380 degrees F., or 1100 degrees C. I know iron melts at 2,000F, so we are hotter than that. I am not thinking biology, but chemistry. I have 3 compost bins and a big garden. That is where biology fits for me. Not a criticism of your idea-just another thought. Tom.
  19. Hey; We can't buy Caro syrup here in Canada either. It's any cheap syrup. Aunt Jemima works. It's the stickyness you want. Don't be using your good Canadain Maple Syrup for this job. Make some pancakes for that. T.
  20. Hi TJR, is that by weight or by volume? I just go a table spoon of your vinegar and a spoon full of syrup added to a goop of your wet clay scraps. i go by eye. Just mix it up so it looks like a paste. If too thick, add more vinegar. You will only need like a quarter cup of mix. T.
  21. Don't bisque. Spooze is a repair recipe for raw clay cracks. You goop it on, let dry, then sand, then bisque. T.
  22. Spooze; 1/3 your clay body 1/3 vinegar 1/3 Caro syrup or other cheap sugar syrup. Mix it up. Put it on to repair. Let dry and sand to taste. TJR.
  23. My previous studio had an exhaust hood from a restaurant, suspended on cables screwed into the ceiling worked great. Was cheap. Had a squirel cage blower and metal flexible hose leading out a window. The trick was remembering to turn it on. TJR.
