  1. I never said I was good at it.... Marcia, I have no doubt your Raku kiln is cheap to fire. It would almost have to be, as you seem to be firing it all the time. You're firing it right now aren't you?....Be honest, as the first step is admitting you have a problem. Jed Benzine, are trying to get me in trouble with Marcia?.....you signed my name to you last message to her. You know the one I'm talking about....lol Jed
  2. Making meth with a propane torch......can you say BOOM? Jed
  3. The day I began pushing start on a pre-programmed electric was one of the best days of my life! It that kind of like the two happiest days of a man's life?...... The day he bought his first boat and the day he sells his last boat? Jed
  4. That was my homework for yesterday. But since the kiln was sold, I did not follow up on it. I will need to do this for next time though. jed
  5. I bought an old Paragon 18" wide x 26 deep for $50. I made two burners from black pipe for $24. I have two old hair dryers for the blowers. The base of the kiln is old cinderblock. The lower part of the chimney below the damper is hard firebrick and the chimney above the the damper is medium duty brick. I made the damper from refractory clay. I made an O2 sensor from a car oxygen sensor, a $5 micrometer, and a 1/2 in dia x 4 in long tube of Mullite refractory from E-Bay for $12. So total investment so far is about $170. I will invest another $100 for the outer insulating layer. This will give me a 7 inch kiln wall, floor, and lid. I have about 2.9 cu feet of usable space for firing. I can acheive good reduction results. I have had problems getting to cone 8-10. This is why I am adding the insulation to the outside. I am still learning how to fire gas, so it is still early for my final assessment. I must admit that the first time I got a nicely reduced pot, I was hooked. Jed
  6. It just means I have more time to perfect my conversion gas kiln... Now I have time to make a 3-4" insulating layer of fire clay, lava gravel, and refractory around my little conversion kiln. One bag of refractory ($50), one bag fire clay($35) and 3-5 5 gal buckets of lava gravel(free) should give me a cheap insulating layer. Will cover all sides, top, and bottom. Why do some get the great deals? Jed
  7. The school stopped the auction early and sold the kiln for $150 to someone who had pull. Jed
  8. How do I move this small monster? Is there a mechanism that Alpine uses to do this? Jed
  9. My house was build all electric. So I am buying a new tap from the city line in front of the house through the gas company. There will be a regulator to adjust pressure to the kiln. If I choose to supply natural gas to the house I will need a second regulator to the house line to reduce the pressure to 0.4 psi, which is normal house pressure. Jed
  10. He quoted $799 for a larger meter set at 2 psi which should supply 1,200,000 btu/hr., double my current need. Since this is a new tap, no permit is needed. I still will need a permit to tap into the meter on my side of the meter with the 2" line going 15ft to the kiln. The next stop is City Planning dept. Jed
  11. The gas guy is coming to house Fri. He said the pressure at the tap is 45 psi. I will ask about Sprague large volume meters... Thanks guys, you are great. Jed
  12. The owner said he had uneven heating with the top getting hotter than the bottom. Can that be overcome with packing and soaking or is it just the way these things fire? The controller does not look like anything alpine now has. On the left of the controll box are about 12 buttons grouped in sets of two or three. Neil would you remember how this works? And are old instruction manuals available? Today I have to see if I can pull a 2" tap with pressure at 14 WC. Jed
  13. There is an Alpine HF24 updraft gas kiln with controller for sale not too far from my area. The serial Number is 95115, I think it may mean that it was built in 1995. It is IFB 2800 with power burners. There is no fiber blanket material. Wals are 7-8 in thick. see pics. The furniture is not included. What would be a good price on this model KIln? Jed
  14. Thank you John..........I'm still on the steep end of the learning curve. By-the-way, how long is the learnig curve steep. On second thought....don't tell me. Jed
  15. Thank you. That really helped. I have saved a copy to my hard drive and paper collection. Jed
  16. I went there first. It helps for common frits like Ferro 3134, 3124, 3110, but not many others.... I'm still confused!!! What I would love is a chart that breaks down firing range, type frit and matching COE. (kind of like the following.) I' m not asking for much..... ....Right? A. Low fire frits............................COE .,............................. Lo........Med......Hi 1. Boron. 2. Lo aluminum 3. Hi aluminum 4. Lo calcium B. Med fire frits 1. 2. 3. 4. C. Hi fire frits 1. 2. 3. 4. D Specialty frits. It would be great to have 3 examples of each category giving a range of COE from lo, med, and hi. So if there is an OCD potter out there that has anything like this alreday made up, please share. Otherwise, my OCD tendencies will force me to expend much energy, try to create order, and go against the second law of thermodynamics.....yuk. Jed
  17. Does anyone have a brief list of the most commonly used frits and their uses, properties, and effects? Jed
  18. Yes those letters are real. As Chris said staph is everywhere. Anywhere mold and midew grows, bacteria will be there competing for food. Not all staph is created equal. Staph epidermatis is a normal bacteria that is on everyone's skin. It rarely causes problems and there is no reason to get rid of it unless you are headed into surgery. Most of the bacteria on our skin is protective. They compete with the bad actors like Methicillin resistant Staphalococcus aureas, knowm as MRSA. The overuse of antibacterial soaps have created the MRSA outbreaks we see today. There have been many articles showing that playing in the dirt as a child is protective. In fact children who play in the dirt have fewer allergies as adults. One could make the arguement that potters should have a better immune system because of their clay exposure. If someone brought samples of clay into my InstaCare I would love to do the testing. It would break my routine of colds, flues, broken bones. It could probably be written up as an interesting case study looking at what bacteria is found in ceramics and if pottery would be protective against bad bacteria like MRSA. Although I have had a little old lady bring in over 100 jars of fecal material, so I could "examine it all." And yes Chris I did "have the nice young men in their clean white shirts come and take her away." Jed
  19. Now that sounds like a great post graduate study project. If you live near an University you could see if any microbiology majors or pottery majors need a research idea. If you want to do it yourself, take samples of your different clays to your PCP (primary care provider) who can send it for bacterial culture. You could also ask your health dept to test it for you. If you want to reduce the spread of staph in your studio, bleach wipes are great to wash down surfaces. Throw away your antibacterial soaps. They make the problems worse. Unless you are otherwise allergic, ask your PCP for Bactroban ointment. Apply to lesions and nostrils three times a day until all sores are healed. Good luck, Jed Gardner M.D.
  20. Grobert USA catalog. Page is www.grobertusa.com. I noticed yellow ochre powder is available from them also. You mentioned it in a post 4-5 months ago. What were you using it for? Jed
  21. My catalog is at home and I don't know without looking. I will have to pull it out. I haven't done spincasting or silverwork for almost 7 years. My middle son and I would do it. It was my way of building bonds. He has since gone off to college and has no room or time. So I have all of the equipment waiting for him to settle down.... Once he is settled, then he gets all of the silversmithing equipment. My other son has the forges, blades, and anvil. We got into blademaking together. Same Idea...I support their interest, help with equipment and they get a skill/art they can continue in their life. I'll look this evening when I get home. Jed
