  1. Hey all! My first volley of research didn't garner much, so I figured I'd see what the forum has to offer... A friend of mine would like me to make something for her in a bright lime green (see attached photos for examples of the color). Any suggestions for a commercially-available glaze? PLEASE note that I don't mix my own for various reasons, so unless you're going to mix it for me and mail it (an option I'm not averse to if someone is willing), I have to go the commercial route. Any brand is fine, but it needs to be either ^05 or ^6. Suggestions? Thank you all in advance!
  2. I wanted to post some of the other glaze test results from my firing last week other than the glazes that contained the Alberta Slip. I have been using a glaze called Flowing Green, very common, A medium green color, breaks brown where thin. I tried several variations using this glaze and the Alberta Slip glazes. The photo of the mug is Flowing Green on white stone ware. It is applied pretty thick on the top. The test tiles are: #294 Alberta Slip Base under Flowing Green, Redrock #253 Flowing Green under McGruder Red #255 Flowing Green under Selsor Temmoku I had a couple of more
  3. In another recent thread, member TJR made an interesting observation. He pointed out that what customers want has changed significantly since I began working, back in the Stone Age. He implied that traditional glazes such as celadons and temmokus are less likely to find fans than they once did, and that white and colored glazes are more popular. That strikes me as okay, for me personally. I started out as much a fan of the Leach tradition as you were likely to find, and my early glazes reflected that devotion. But after the first few years, I started to wear out a little on glazes from
  4. I am a high school teacher and I found a beautiful commercially produced Turquoise glaze that tends to run, a lot! I have never relly gotten in to the chemistry of glazes. I have always used prepared commercial glazes. Simple, easy to mix and cheap. My question is, what can I add to the glaze to reduce the amount of running? I believe that the running is a result of firing the glaze to too high of a temp. However, if I fire to a lower temp to keep the Turquoise from running, the other colors will not fully mature. With so many students, I don't have the capacity to do a firing of ju
  5. I was loading a kiln load up today, glazing as I went, loading each piece as I usually do into the kiln when finished with it. I set of my pre waxed taller pieces aside, working on the patens(plates). I go through a series of dip glazes, sprayed and poured glazes, and some atomized on stains. I then finish the foot ring by using a damp sponge on the foot rings of the patens while on the griffin grip. Chalices are done much the same, in batches of 2 or 4 to match patens. I placed the lid on the kiln(mine is not hinged, but has two handles) leaving a little space up top for early venting. I als
  6. Here is a link to my Facebook Color/Colour in Clay page ... https://www.facebook.com/groups/286531511532039/ The first post with pictures is from a newbie who is noticing significant fading on a colored clay glazed piece that has been run through the dishwasher several times. Any comments would be welcome as this is a new problem for me.
  7. 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 kn
  8. Hey guys what ceramic supply websites do you prefer? Which have the most reasonable prices and what were your experiences with them?
  9. 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
  10. 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
  11. 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?
  12. 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?
  13. 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 t
  14. 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
  15. 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
  16. 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!
