    Kiln Value Assessment Needed

    Okay. Thank you for the detailed thoughts. This helps a lot.
  2. Hi Everyone! I have decided to sell my old Olympic kiln and was wondering if I you would be willing to go over the description and photos and give me some idea as to how much, in US dollars, do you think I should sell it for. Thanks! -Charlotte Olympic 2327H Manual Kiln Sitter kiln. Single phase, 240 volt, cone 10, 45.0 Amp Kiln. This kiln has been in continual use in my studio since 1992. Very reliable and I have made many thousands of pots using it, mostly to cone 04 bisque and cone 6 glaze. Selling it because I have a new kiln and I realized that I don’t really need two full size kilns. This has been a really wonderful kiln to use. It has a lot of life left in it for someone to make fantastic pottery with. Features: One owner. Dawson LT-3K Kiln Sitter - Sensing rod, weight and claw in good, useable condition. Cone supports need to be replaced. I ordered new ones and those are included. Kiln Sitter also has a timer. Elements are new- Replaced these last year. Kiln has gone through a number of firings with the new elements, so they are properly conditioned and work very well. Wiring and Switches in very good condition. Fire brick walls of the kiln are mostly in excellent condition. Only one small place on the wall (see photo) shows a missing piece. This is no big deal as the element in this area is properly held in place with extra kanthel pins. Lid handle has some corrosion on it, but is functionally sound. Lid brace is in good condition. Lid fire brick slab is in good condition. Metal jacket on kiln is in good condition with only small cosmetic discolorations. Floor slab of the kiln has some cracks in it, (see photo) but they do not appear to go all they way through. (Ware was never fired directly on the floor, but rather on bottom shelves, the reason the floor is free of glaze drips.) Kiln comes with original metal stand. Kiln comes with original Dawson Kiln Sitter calibration plate. This plate is used to calibrate the kiln sitter, so the kiln sitter functions properly. Power cord sports a nema-650 plug. The plug had been replaced. The power cord is in very good condition. Kiln comes with three (two of which are original to the kiln) peep hole plugs. Kiln comes with original lid wedge. Kiln comes with original manual. Kiln comes with assorted boxes of kiln sitter cones. Cones 018, 06, 04, 6, and 7 mostly. Kiln is sectional, with separate power boxes, that plug into each other, so it can be unstacked for transportation. Kiln sports three switches: low, medium and high. Can demonstrate that it powers on and heats up, as it is currently sitting next to outlet.

    Paragon LT-3 Kiln Over Firing

    Hi. Are the cone supports straight? It's possible if they are a little warped inward, that might cause the problem.

    Kiln cross country moving preparations

    When I was at Olympic Kilns in Flowery Branch, GA, having just finished ordering a new kiln (MAS2327HE), the sales representative talked me into using my own truck to transport the kiln home, saying it will be much safer in my truck versus sending it using the contracted tractor trailer truck. I have a cap on my GMC Sierra truck and the rep came out and measured it to make sure it would work. When I returned to pick up the kiln, they had me back up to the ramp of the loading dock, at just the right height. They then slid the kiln off of a pallet into the back of my truck using several thick sheets of cardboard. The kiln was well wrapped in plastic wrap (with foam sheet between lid and kiln body). They discouraged the use of any straps. Of course, I only had to drive a little more than an hour to get it home. Traveled like a dream. Unwrapped it, did all the taking apart, unstacking, carrying to workshop section by section and re-stacking, putting it all back together, as per instructions and all was well. It was a cool experience.
  5. Stephen, With a kiln sitter kiln, when the kiln sitter finishes and the weight drops and shuts off the kiln, you can turn the kiln back on using pencils. With the eraser part of the pencils, lift the weight slightly and push in the plunger. Turn the bottom two switches to high and the top one to medium, or high, and watch the witness cone packs until cone 6 bends to your liking. I have done such as this on a number of occasions to even out the temperature from top to bottom, or once when I wanted to get the load to cone 6 finish when something went wrong with the cone in the sitter. I always use witness cones. Two packs. One on the bottom floor, one on the top, with at least the top pack viewable from the top peep hole. If I am firing a load of glazed ware that I am particularly worried about properly firing, I will make sure the bottom witness cone pack is viewable from a peep hole, too. I always check the witness cones, several times during the very last part of the firings. Because of the witness cones and my vigilance all the almost disasters ended up being good firings.

    Help my slabs are cracking up

    Hi Julia, Sorry, no. I have no experience using silica sand, I am afraid. I simply bisque fire my tiles flat on the shelves and stilt them in the glaze firing. I haven't had any problems. I would have looked for a solution had I seen cracks, or splits, or whatever, but no... all have come out fine. Maybe I've been lucky. I don't know. I have made some large, but to be fair most have been small tiles, 5 inches by 5 inches, or 5 inches by 7 inches. Maybe that's the reason I haven't run into any problems with them. Hmm.... I wonder if the following makes a difference: When making tiles, I use the technique I learned when I was a kid from a potter who railed that the only correct way to create slabs was to throw them. It involves throwing a flattened ball of well kneaded clay down on a piece of cardboard at an angle. The bottom part of the clay will grab on the surface, while the top part of the clay will stretch in the direction of the throw. It's reminiscent of the way a pizzeria cook stretches pizza dough, only in the case of clay, it is stretched by throwing it down, lifting it off, turning it and throwing it down again, repeatedly until the slab is the desired thickness. I have been practicing this since I was ten, so it's easier for me to make slabs this way, than any other way. Maybe the tiles I cut from these slabs are more resistant to cracking because having been stretched, most of the clay particles lay in the same direction. I don't know. It's an idea.

    Help my slabs are cracking up

    Hi Julia, I have done a lot of the sort of work you are attempting. In my case, nearly all commission work with hard deadlines. Lots of pots and/ or tiles with sprig (2D relief) work on them. So I know. Always pressed for time, seemingly. Racing to get things made, so they can dry as slowly, and as completely, as they need. In this regard, I find myself throwing pots, or making tiles and then when they are barely stiff enough to be handled, pressing and pulling out the sprigs from the molds and applying them on to the pots, or tiles when everything is still quite wet. I use a wire brush and score both sprig bottom and ware body. I make two passes of scores, at right angles of each other. Dabbing a drop of water into the score on the ware, to displace air bubbles and to help further seal the bond, I will then place the sprig on. Then, this is important, I always wipe my fingers, quickly, and try to get them as dry as I can. I found that pressing the soft wet clay sprig on to the pot does very little deforming if the fingers I am using to press with are dry. Try it. As for thick sprigs, especially on pots that can’t have pin holes through their bodies, stabbing with a pin tool into the sides of the sprig, parallel to the plane of the tile, or pot, but not into the area of the scored bond, works great and allows it to out gas any residual moisture just fine. These deadlines, they are sometimes a beast! I have been known to sprig 40 pots in a sitting. Knock on wood, I have only had three sprigs ever come off and one blown off, and that out of thousands of pots and tiles. At the time, I noted that friends don’t let friends sprig at 3 am in the morning. I got sloppy and didn’t score with my usual care. Anyway, those particular pots were fired artfully tipped over enough to, I hoped, to keep the sprigs from sliding and I did succeed in fusing the sprigs back on in the glaze fire. And, I made deadline, got paid, and all is well. Best wishes that everything goes well for you and you make deadline. -Charlotte
