  1. Yogzula, i don't know what your situation is, or if you have the space and infrastructure for a large kiln, but if you are patient and do some looking around kilns can be had very inexpensively. They are large and sometimes difficult to move, taking them in pieces is time consuming and can be challenging, so sometimes people just need to get rid of them...fast, and great deals can be had. I got both my gas kilns that way, one is a nice home made 10 cubic foot gas kiln i paid $200 for based on a trent thomas design and moved it brick by brick, and the other is a 16 cubic foot alpine i was give

  4. hi min, very smart to be extra careful, but i don't believe this stuff is any worse than any other fiber insulation the particle size is pretty large. MSDS sheets have a way of making everything seem pretty bad for you, the fibers that produced health issues in lab animals were engineered to increase exposure and were different than what we are using. "There has been no increased incidence of respiratory disease in studies examining occupationally exposed workers. In animal studies, long term laboratory exposure to doses hundreds of times higher than normal occupational exposures has pro
  5. the up side of putting all that fiber insulation on top of my kiln is the hummingbirds in my area have the warmest nests in town, its kind of cute watching them fly over and steal little pieces when its building time.
  6. Crusty, when I'm firing my small electric kiln sometimes ill stack 3 or 4 inches of old random pieces of fiber insulation on top of the lid of the kiln. I've done this quite a bit the added weight is minimal and although i was at first concerned this might promote cracks in the lid bricks, i have not had any problems, when i do this the cooling cycle is much longer. my gas kiln has fiber on top also, it was old stuff i had laying around and i think it helps, there is a picture of my gas kiln in the gallery you can see the fiber stacked on top.
  7. there are two chemicals i think that we used to use years back when making raku kilns out of old 55 gallon drum and small galvanized pails to glue fiber insulation in place, colloidal silica and sodium silicate... are either of these the agent you were referring to?
  8. i was in downtown Capitola shopping with friends a couple of months ago and in the little nature store where they sell all kinds of sea shells and rock specimen type stuff, in between the dried star fish and sea urchin shell was a big basket of little natural sponges and they were really cheap. i don't remember how much they were charging for each one, but it was not very much, so i bought a few and they work just fine.
  9. Kath, im not necessarily saying you should apply more glaze to your pieces, I'm firing at a much higher cone rating and as you said you work did not reach maturity. a trick i was taught along the way to help when you need to reglaze a piece that is already fired is to put it in the microwave on high for a minute, this will do two things, it will heat the piece so the re-dip (spray,brush) in glaze will dry thicker faster and somehow the surface of the fired piece is more receptive to the application of fresh wet glaze.
  10. it sounds like you have everything under control, but ill add my 2 cents and hope that it is additional information that is useful. if you have successfully fired the kiln in the past then i think the setup should be ok, i have both updraft kiln and down draft, the up draft kiln will not have a chimney stack, if i have not fired a kiln for a while the burners will collect insects dust and spider webs and need to be cleaned, if you are firing off lpg the tank needs to be of a volume that will provide sufficient vapor delivery to match the BTU demand of the kiln, if the tank is almost empty it w
  11. Cambria is a nice little town, it has some gift shops and a few galleries and restaurants, but not enough to keep you entertained for more than a couple of hours i don't think. next to cambria is moonstone beach, if you are lucky on a low tide sometimes these gems can be found. the area around cambria has a number of wineries you can visit and Hearst Castle is a short drive and worth seeing if you have never been there. a few miles north of cambria the is a wonderful location to check out the sea lions. There is a beautiful restaurant and bar overlooking the ocean just a bit south of Carmel in
  12. In China they are masters of taking it in chunks and making it big... i got the chance to spend a little time in one of the factories in Jingdezhen and try some of their clay on one of the big wheels. it was an interesting experience and would take some practice to get used to as the clay is very soft and the wheel had one speed... fast, the wheel was connected to some giant engine located under the factory and the large wooden batts were secured to the wheel head with soft clay. in the photo showing the two potters wedging clay you can see three large balls of clay, that's the amount used in
  13. one of my teachers a few years back was a great thrower and i really admire his work his name is Michael Berkley www.pitfiredpottery.com, he had an interesting way of getting across to his beginner and sometimes not so beginner students how to center clay. it was just using the basic good body position, but he would have them hold a brick in their hands and press the brick into the clay instead of worrying about hand position or what your fingers were supposed to be doing. as long as they kept their hands steady depending on how pressure is applied by tipping the brick the clay can be conned u
  14. i'm not much of a glaze person and have relied on commercial and studio glazes a lot and only recently have been mixing my own in an effort to get results I'm happier with. so I've tried one batch of laguna crystal palace, i think it was around 20 pounds of dry glaze to start with. i did a number of cone 10 firings in a small electric kiln with an automatic programable controller and experimented with a range of soak periods from 15 min stages to stages of 2 hours, the soaks were in the 1900 to 2100 range if i remember correctly (whatever is posted in the firing schedules on the Laguna web sit
  15. great little set of pipes, i like the feel of your work and the mugs look comfortable in their skin.
