  1. Hi All, I am looking for glaze book recommendations for beginners. Like most artists I am a visual learner so that would be helpful to take into account. I currently work with earthenware clays so it would need to address low fire glazes. Fortunately I have most of the raw materials in my studio which came in a lot purchased off a former 1970s potter (who also worked with low fire clays and glazes). The collection is probably about 90% complete and even has a few materials no longer being mined - and a number that are now considered unsafe because of lead, cadmium, etc. Of course, I know to be extra careful working with these and to not use them for functional wares. I had hoped I could just start my glaze making experience by following some recipes I have found online and learning as i go along. I now realize that to achieve the best results I need to gain a stronger understanding of the chemistry involved. (I chose physics over chemistry in high school so am seriously lacking in general knowledge of this science to begin with) I would love to get some recommendations from other potters, especially on which glaze making books got other self-taught potters started. Thank you.
  2. Hey guys what ceramic supply websites do you prefer? Which have the most reasonable prices and what were your experiences with them?
  3. I've been throwing with Standard Clay 630 (^6 white stoneware) this year and have really been enjoying using it. However, I used a few different commercial glazes with it and have found that some of them are crazing. For example: Amaco HF-9 Zinc Free Clear Amaco PC-40 Celadon Amaco Sahara Yellow Coyote Light Blue Gloss All of these are translucent, so maybe that's the common thread? Because Amaco's Ultramarine, Amaco's Amethyst, and Coyote's Buttercup didn't craze at all. But I tried my local studio's zinc-free clear, and it didn't craze. It's not the cooling, because nothing is being fired any differently than other pieces that don't craze. So I'm thinking it's a COE / glaze fit issue...but I am a total newbie at glaze chemistry, so I bow down to the collective knowledge of the forums and ask if there's anything I can do to my commercial glazes to make them fit. Other than changing clays, of course. Which is probably what I'll have to do, but I like the 630 the best out of the ones I've tried and I really love the celadon and light blue glazes... Also, how serious is this breed of crazing? Is it really *that bad* when it comes to using them for food/drink?? (Regarding clays.....I know some of you swear by clays made by Highwater, Laguna, etc., but I live in Pennsyltucky and getting anything other than Standard isn't an option right now. Also, I am a hobby potter and porcelain is out of my current league.)
  4. Hello all! I need some clarification on kiln firings & a little help identifying some glaze problems. So first, I've been taking classes at a community center. I have ceramics/pottery background but I don't know it all when it comes to firing a kiln. I know the basics and I've loaded/fired bisuqe kilns and low/mid fire glaze kilns [it's been a couple of years though]. My issue/question here is: I've noticed that some greenware has been loaded into a low fire glaze kiln [cone 05 I believe]. Is this okay to do? I have never seen it done before & just wanted to make sure it wouldn't jepodize the integrity of the work. Also, there has been issues with glaze crawling and peeling all over peoples work. Does this sound like a dust issue? I've never had issues with dust before so this is a new concept to me. I'll have to post a picture later. Thanks!
  5. Hi all my local hardware store sells a product called Black Oxide which is used to colour cement. Has anyone tried this is a glaze recipe? I dont know the chemical formula as their product website does not give that information, only that it is derived from anthracite and coal. So I dont know if it can be used for glaze? Can anyone help?
  6. Just starting to do pottery at home. Have inherited many bags (40+) of cone 4-6 glazes, stains and oxides and I am overwhelmed by all of it. I have done some pottery before but in a school where all the material was premixed. I know how to mix powdered glaze with water, no problem, but don't know how to mix the stains and oxides. Plus, I don't know where to start. Do I start trying out just one glaze or do I prepare small batches and do a series of test tiles?
  7. What The Heck is Glaze Chemistry All About? Sharon Art Center Campus of New Hampshire Institute of Art Professor John Baymore This one day, seminar-type workshop will provide participants with a basic understanding of the core concepts that can impact the creation, use, and evaluation of ceramic glazes for studio use. The instruction of the widely popular ceramic chemistry calculation software, Insight, and its priciples will be presented. Troubleshooting of fired results, “food-safe†qualities, health and safety, legal requirements, and ventilation concepts will also be touched upon. Handouts will be provided to all participants. Students are encouraged, but not required, to bring a PC or Mac laptop to test out a trail copy of the Insight software. Prerequisite: Intermediate ceramics skills.

  8. I work in an Art department in a school and today I discovered a selection on unopened glazes from the Fulham Potteries. Does anyone know if these glazes are collectables or have a historic value? Many thanks
  9. Hi Eveyrone, thanks for all the help so far on this site, its a fantastic community! i have a small question about Liquid Bright Gold; can i apply it over a glaze that i have already fired - at witness cone 06? i have some pieces that were fired at 06, then glazed and fired at 06, now i would like to add some further decoration with the liquid bright gold, which says it needs to be fired to 019-018. so the simple question is: can i apply it over already fired glazes? sorry if it seems a stupid question! i'm learning all the time! thanks so much! Toni
  10. Hello guys! Wasn't sure if this is the right board to ask. Any advice on up-to-date online store with ceramic glazes with worldwide shipping, please? Besides c*micartcart.com, quite narrow range they have. Thanks in advance!
