    castable refractories and other ways to make heat work
  1. Micheal Cardew Ray Finch Phil Rogers taught me loose is ok. I expect these fellows are listed elsewhere and maybe I've missed them here but anyone finding this list should know these folks - even if mentioned more than once.
  2. Goldmark is a good source for videos. Youtube has some but there is a feed from the UK that is better - can't remember it atm. Phil Rogers is fun to watch. There are others including some black and white of Shoji Hamada. *http://inspirations.ceramic.nl/Technical/overviewtechnica.html not the site i was looking for but educational none-the-less
  3. ​Are you cutting off and reusing the bats or grabbing a fresh/dry one? ​ ​​Particle board bats will absorb moisture and have given me the same grief.
  4. How Long To Reach Cone 9? Is It My Kiln?

    There has been a lot of heat-work done. Generally speaking an undefired kiln can be refired with good success. It's unfortunate timing for your Mums day pots. This will be a good learning experience though - Goodness knows we have all had a few. *you may already be aware of the Orton chart: http://www.sheffield-pottery.com/v/vspfiles/downloadables/cone_wall_chart_horiz.pdf The section in the lower right that explains a bit about the idea of heat over time may not be the most comforting at this point but it helped me understand how heat works.
  5. How Long To Reach Cone 9? Is It My Kiln?

    You need to fix something. The kiln is firing way too long. *I sometimes have issues with reading comprehension obviously but electric kilns should never fire for days in a row. You need to turn it off and trouble shoot the elements/electronics.

    This kiln has a kiln sitter, there are no relays or control board. If it is a fried switch, one of those costs $85. ugh I should stick to lurking
  7. How Long To Reach Cone 9? Is It My Kiln?

    My money is on a burnt element. "If they all burn, then they're probably worn out." This I suspect might be a moment of dyslexia - if not I'm confused as well. If the kiln is older but still in good shape as far as the fire brick goes it is definitely worth some love. I'm no electrician but I do know the switches and relays that make an electric kiln run are relatively simple to work on and cheap to replace. A qualified/experienced kiln tech/electrician type person will be able to fix the control board easily if necessary. Those elements are probably tired and on their way out. iirc they cost about 50$ each and will set you up for another 40+ firings. The are not much fun to remove and replace but with some good side-cutters and needle-nose the job can be done in an afternoon. It sounds like your relays are still 'clicking' on and off? afaik relays will fail in one of two positiions - on or off. On is bad and will cause a runaway and is one of the reasons to never turn your back on a kiln near the end of it's firing. hope this helps a bit
  8. I remember a young fellow who used to stir up buckets of glaze in an old home studio. The day a brittle bucket of tenmoku let go its' metal handle was the last day he ever trusted a handle on any bucket of glaze ever again. ​ ​*its/its' or w/e the possessive punctuation is
  9. "...sometimes we don't READ THE QUESTION accurately.......so we go off on tangents, answer what we THINK we read..." ​The folks here and on other forums who actually listen to people and form polite and well informed responses deserve a lot of credit. ​I usually regret posting for one reason or another. Most of the time this will come back to not listening very well. ​ ​
  10. White Glaze

    This sure sounds/looks like too thick an application. Yoghurt for me resembles a slip more than glaze. Now a nice, thickish gravy...maybe beef...over Yorkshire pudding...yum...
  11. Functional..foodsafe.

    95% BaCO3 sounds more like a stain and certainly not anything I'd want to use as a glaze. iirc barium *not correctly remembered* can float around and flash on pieces even after the original firing? food safe = functional for me
  12. Glaze Testing, Charts & Note Taking ?'s

    I'm in no way associated with the app 'Pottery Notebook" but it is an inexpensive(1.50$) option available through google play store. ​ If you aren't already using calculation software do it sooner than later. Glaze testing with pencil and paper was fun and 'all' but I sure do enjoy pulling out my phone(InsightLive) to see what adding/subtracting/substituting this or that will do to my percentage of what-not. ​ ​cheers! *most new projects/ideas are still 'mapped' out in pencil though. In this regard i can appreciate where a spreadsheet might come in handy
  13. After finding out a few hundred of my test tiles got 'downsized' into a dumpster I regret not taking more pictures. I have some notes but a future without my tiles just never occured to me. I'm moving into the ^10 reduction side of things a bit and will definitely be taking better notes and more pictures. Thanks for the gentle reminder!

    I took a closer look through my bookmarks and found this somewhat obscure and off-topic link: Glazes - for the Self-reliant Potter http://www.fastonline.org/CD3WD_40/CD3WD/APPRTECH/G17GLE/EN/B483_14.HTM
  15. Iron Oxides

    I just happen to have a few bookmarks: *one already mentioned http://ceramicartsdaily.org/wp-content/uploads/2011/03/cmtechnofileiron.pdf http://web.ncf.ca/bf250/glazeiron.html At the risk of drawing the ire of the more lettered technicians if you are just starting to melt stuff don't worry about limits and masses and software too much - all that can come later. It all comes down to finding good glass and if you can 'feel' your way through a recipe the results will have more meaning when it comes to fixing/fiddling. Hessleberth and Roy iirc have a good article on making 'good glass'. I'll try to find it again - or maybe someone has the link. re. Black Iron Oxide Mine requires no pounding although the semi-arid climate might have someting to do with it.
