  1. Past hour
  2. I admire how pragmatic so many of you are when a clay-tragedy strikes. If I get a crappy outcome, I am half heart broken. If I drop a bin and shatter some of my best stuff, I want to crawl in a hole and have a pity party. The only thing that has helped was that I was taught---on a very philosophical/zen-ish level, by an artist I respected---that I should never robe myself with the arrogance of thinking that my stuff is "precious". That sticks with me just enough to take some of the sting out when things go awry.
  3. tons of other things go with it. it is not mine, i will forward an email from the owner if someone is serious about this great kiln. PM me.
  4. My kiln load was a bust, total dookie, not a single piece looking good. I thought the longer bisque might eliminate some issues with this glaze I am using, but instead it just over fired. I knew when I was glazing it was going on pretty thin, and it was. Gross thin zinc glazes yuck. I'll try reglazing but I have some pretty low hopes. They can't all be winners, right?
  5. Teapots definitely more involved. Suggested viewing for some more insight and general pleasure: smarter everyday - laminar flow. (You tube) free education and super high speed camera. Sometimes seeing is great for analysis.
  6. Funny you should mention this article, I just read it recently and it prompted me to post this query.
  7. Today
  8. I truly have not come to terms with this in my head except to say the handle shrunk significantly more than the body and exceeded the tensile strength of the clay pulling itself apart. Everything is so sturdy and well done that it is an interesting failure.
  9. I had a handle crack like that, but only when I tried to dry it to quickly, to get it in a kiln load, not during a firing.
  10. I am sympathetic towards her point of view but too vitriolic for me. Often for those that truly know something they become offended at those that do not. Maybe mandatory minimum IQ is the solution. There are a bunch of reasons to hate and far fewer to like especially in a hyper charged creative environment. In twenty years of teaching I noticed three distinct personalities. One was that of making money (Ho hum) one was that of superiority and being all knowing (Ok I guess) and one was that of teaching and enjoying the natural expansion and progression of students knowledge beyond your own. Not scientific but the first two types were often negative and hated something daily. The third seemed happy to learn, happy for others new knowledge and generally happy to see humanity progress. I sympathize with her point, but only see it as an opportunity for her to educate others. I am half Polish half Italian, maybe I should tell her how incorrect many folks are about my heritage. Just sayin, I think I prefer to meet, greet and as Liam says sit back and enjoy while I can. My wife and I Met a group of strangers from Cameroon two days ago. They spoke little English, no French and no Polish ..........Great Fun, interesting culture, memorable thirty minutes of my day, learned a bunch and took lots of pictures all smiles and well wishes! the experience - free for all, monetarily profiting from the experience ........... not in my wheelhouse.
  11. It's hard for English speakers to interpret concepts that have a name. There's nothing special about words here as a concept so it can be hard for us to understand the big deal about using a word (or phrase). And someone Japanese probably has the same difficulty understanding why westerners are so careless with the words they use. Lost in translation is a great phrase because there are concepts that are hard to explain with words, and feelings and whatnot. Japanese is really cool, they have stuff like onomatopoeia for textures and feelings and stuff, it's way beyond comprehension for me, I just try to sit back and enjoy. My wife is Japanese and I get to hear about the misuse of words a lot, she kind of understands now and can see it from the western side, our words don't carry the same brevity and we use them like they're free. I liked her article, but I think she could have done a better job of explaining why it makes her so angry.
  12. https://makikohastings.blogspot.com/2019/05/naming-does-matter-my-thought-on.html?m=1 I’ve come across about 5 references to this blog post today, despite spending a total of 20 minutes on social media. So after finally reading it, I feel very strongly it belongs in this conversation right here. It’s written by a Japanese artist who has spent half her adult life in the UK, and tells of her frustrations in watching words and concepts that are deeply held and respected within the Japanese culture used and abused by many from the west in order to sell things. She speaks about wanting to encourage those who are curious about and inspired by her (and other) cultures to investigate them, and learn. Learn so you actually DO honour what you are learning to love, and so that you don’t accidentally insult it. Most importantly, she has a reference for westerners that she recommends on the topic of Wabi Sabi, which is a term frequently misused and abused by potters who have an incomplete and often wrong. understanding of the concept.
  13. Yesterday
  14. Pourable epoxy works wonders for the interior. Vases, not food grade stuff though.
  15. Hi guys, I have been trying raku firing at a center where I was introduced to ceramics few months ago, So far I have made some vessels but they are not suitale for water retention. I wonder if there is a way to make raku vessles waterproof? I have heard of a product called Thompson Water Seal in USA. and someone suggested to coat the vessel internally with a mixture of boiled starch so as to seal the clay. Any suggestion? I live in Europe, so any specific product I can get my hands on without incurring in huge import fees is very much appreciated :) Thanks for your inputs. Pierpaolo
  16. Really interesting handle crack, sort of opposite of normal. Usually we see the highest stressed area crack first which would be the outside of the handle. These appear to have been influenced by the cup body itself. One thing, great handle attachments they were able to resist a rotational moment!
  17. Fortunately opened kiln late when too tired to have any sort of energy wasting actions..but it did send sleep away forca few hours
  18. good news. got 2 unfired so I'll keep you posted
  19. Wouldn't want to repeat it! I tried a slow fire to cone 5 yesterday and it was an hour shorter than my fast fire to cone 5, so I don't really know what I'm going to find when I get home from work tonight... I could open it up and see a bunch of nice pieces... Or open it up and start throwing things... Hopefully somewhere in the middle as usual hah. 36 mugs and a vase.
  20. That's my thoughts. cold night top bung out.. occurred throughout the kiln....more good ones lower down. but still cracks bottom shelf top loader... I usually fire first ramp 100degC to 600 then 150 to 1100. only change I did... can't even repeat it to check.ha!
  21. Wow bummer, do you think the power outage caused some mischief around quartz inversion? Pretty rare to see cracking like that
  22. I would like to have glaze chemistry sorted. A time to just indulge in the study of this. Did quite a lot of chemistry but life gets in the way of canning it in glazes at the mo. If you ever read of a 100 plus yr old attaining a phd in this field it may be me:-)))) I guess a strength would be never getting'floored' by results and a brain which is a bit like a dog with a bone when it comes to problems... and. knowing something might just work but may not and doing it anyway....
  23. suely not Min! You hide that well:-))) And others appreciate and benefit from you attributes!
  24. SOfirst time event for old potter. I packed kiln with mugs and bowls. Yes a different glaze but also same clay same ish design old tried and true glaze on half the mugs. some mugs had additions of clay molded pieces attached also. Kiln and scheduled for usual ramping. c 6 firing finishing at 8.30 a.m. one top bung left out. 2 a.m. , I am an old potter used to manually turning up every hour, kiln temp. 480deg. Power out sometime between then and 6.30a.m...no alarm to awaken the sleeping potter..temp 350degC..reprogrammed kiln to go up to 1100 at150C/hr and then usual schedule of 80dc/hr to end and a 15 hold. top bung in. Folk have said it's ok to go this fast , right? I never have before. Result I have12 whole mugs out of 40. rest have a BEAUTIFULLY horizontal crack in middle of handle starting from underside of handle , not quite through the handle so it looks whole from above.Crack is sharp. Second cooling v. slow, finished firing sunday arvo, opened last night. Occurring in both designs and both glazes Bowls crack straight across bottom. ah it's never boring!
  25. All too often, the college courses for teachers, and non Ceramics majors was negligent on glaze chemistry. Possibly for the lack of appropriate teachers, lack in belief that students needed or even cared about it, and as budget required efficiency, was left out of the curriculum for lack of enrollment. I never had one on glaze chemistry, only a general that told us to read Nelson's chapter on glaze chemistry and be ready for a quiz that never occurred. Oh well! best, Pres
  26. You might find some insights to the physics of the tea-pot dribbling phenomena by reading the recently published article (and all of the articles cited therein): I'm a little teapot — Dribble no more: Physics can help combat that pesky “teapot effect” Dutch scientists devised a model to predict flow rate when dribbling will occur.

  27. There are so many things I could answer with here but, like Denice, I'm focusing on glazing. While I've taken college level Cer 1& 2, I learned more about glazing in the Raku class, having to mix my own glazes as part of the syllabus. In the other classes we were directed towards the 20 gallon buckets of glaze and their samples and were told to knock ourselves out…
