  1. looks like the bearing in my brent c wheel(20 + years old) is toast . has anyone had an electric motor repair place replace the bearings. A new motor is around $400, just getting info before committing to a new motor. Thanks
  2. Thanks for the info. I can see things going very bad very quickly.
  3. A very interesting read. I have been done this rabbit hole for many years now and find there is more to go than where I've been. That being said, an early comment on the types of zinc white yellow and metallic. I have been gifted some metallic zinc powder which was used in making battleship gray for the Navy. How would one go about creating a glaze test using this material, if at all. I use a 50% 3110 26% calcined zno 23% sil and a pinch of epk. peak temp 2300f w/5min hold Looking forward to trying something new just rewired my kiln Thanks Wyndham
  4. I use a electric grill with temp control. The wax is candle wax from hobby lobby. Adjust the temp until the the wax goes liquid, but not smoking. If you need to wax large volumes of pots, this method, with care taken, has worked for me for over 18 yrs. The wax only needs to be about 1/8 in. We use a knife to scrape off any excess wax on the bottom. Using wax at this temp, it's not around open flame and is not hot enough to combust on it's own. Care must be taken with any part of a studio . Wyndham
  5. no I'm afraid not but the Texas tile press site videos and tutorial will give you about everything you need. I used a moist, freshly slabbed clay as the master. built a frame 10 in on a side with 1x4 pine. These 2 things replace the metal frame and silicone rubber master he used. Hope this helps. If anything else just let me know. Wyndham
  6. Mine broke down early, but I was not as kind to it as I should have been. I used a rubber mallet to pound the clay into submission Wyndham
  7. This is the Texas tile press but I did mine for about $20 with a wood frame, air tubing and a compressor I had from HF. Mine work fine for about 200 pressing before I made another mold. Wyndham
  8. I have used a hand press for a home made tile air release system. The hydrocal should be fine but if you wanted a little softer die then add about 25 % plaster to the hydrocal. Hobbylobby should have some silicone rubber for the masters. If you need another source, give Rampress a call and find out what they recommend. Wyndham
  9. You might try oven drying 20 mule team. I got my anhydrous from a local supplier. Wyndham
  10. I use borax in one glaze that can have the nasty habit of crawling. It's not due to clay but the borax. It will also act like soda ash on evaporation, making a crust up the side of a container holding the glaze but.... It can make some great effects. I try to use that glaze in the bottom of a pot and layer another glaze on top and not use it on the verticals. Don't use 20 muleteam borax, it seems to have other stuff that makes glazes spit. Other than that, it can be great.................or not Wyndham
  11. You might be able to make a tripod base with some 4x4 post and cement in the base. The shop class should be able to cut and weld either round 3-4 in pipe. Go to a scrap yard that buys steel and beg some sq 4ii stock about 24 in long or round stock that size. If they won't donate they sell it by the pound. You'll also need some flat stock about 2 in wide and 1/2 in thick, 2 pieces about 4 ft long, this is the handle and the ram parts. The base is the most expensive but maybe the shop teacher can help This should be no more than $20 for the steel. I can make up some plans but you may already
  12. Here's where I see an issue, look at the prices. A pot shipped from Europe, sold on etsy for $15 and the potter makes a living & the seller made a profit, how does this fit? Yea, we're discussing technique and I'm off topic but anybody else see the 800 lb gorilla? Wyndham
  13. If possible try to buy calcined zinc, it plays nicer with glazes than reg zinc. I think the 1000-1200 deg temp range drives off chemical water from the zinc, much like drying out a greenware pot where there's physical water and above 1000 deg f driving off chemical water but before sintering and fusing begins. Wyndham
  14. I think 1200 f is about as high as you should go. Zinc starts to vaporize at cone 06. Wiki says: ZnO decomposes into zinc vapor and oxygen at around 1975 °C with a standard oxygen pressure. Heating with carbon converts the oxide into zinc vapor at a much lower temperature (around 950°C).[11] ZnO + C → Zn(vap) + CO Wyndham
  15. I'm a little late for the discussion but thought I'd jump in for a moment I think I see something slightly overlooked in this teaching clay thread. It is something that became very apparant when I took my first classes in clay, some 27 years ago. It takes time for people who have never worked with clay to get the muscle memory to work with clay. Of the few people that I have assisted in learning to turn, it was obovious they had not spent enough time with the wheel or slab or coil to feel comfortable with the clay. It takes time and a few hours a week is not enough to develop these skills
