  1. I am having trouble with Amaco's Potters Choice glazes crawling when layered. I have used them for years and have never had a problem until about a year ago. The issue is specifically when layering the potters choice glazes in dipping form. The Brushing bottles are fine, I have not problem with them. At first I thought it was my students application or the thickness of the glaze. But after endless test I can not figure out what is going on. I called Amaco and they said they were aware of the problem and were working on it. But the only suggestions they had were to stop layering them, only buy brushing bottles and using distilled water. I need these glazes to work in dipping form for my students. I have used distilled water, it does not make a difference. I have thinned down the glaze, doesn't help. I have tried applying the glaze with time drying in between each layer and also dipping them one right after the other, doesn't help. Does anyone have suggestions? Thank you.
  2. Yes, I am tilting at windmills... I've been doing tons of trials with Amaco Velvet underglazes to introduce some bright colors to my pieces, and I currently work only in cone 10 reduction. I know what I'm up against, but still I must persist. I apply the underglazes on leatherhard so that they will be bisque-hardened to better withstand cover glazing. Yes, most of the colors will not be true, but I've found many I like—without a clear glaze cover. What I need to find is a clear gloss cover glaze that will not completely alter so many of the colors. Amaco's own house brand has its problems, including the crazy price for enough glaze to dip pieces, (they offered no help "because we sell a clear glaze") and the best choice at my membership studio still transforms most of the colors, some into a completely different spectrum (see image). Does anyone have a clear gloss glaze recipe with a better hope of allowing the underglazes to stay as true as possible in a cone 10 reduction kiln? When you stop laughing, I'd love to hear.
  3. I have been using the Amaco Obsidian layered with Potter's Choice colors for some really beautiful results. I have planned a new line around this. I had been warned that the dipped and brushed glazes combined don't work well together but I forged ahead anyway because I'm clever. I purchased the bucket of C-1 Obsidian, mixed it, dipped test pieces with it, let dry for 24 hours, layered the PC over, sure enough, crawling. I mixed some gum solution into a pint of it, brushed, layered it, normal results. I contacted Amaco and they have no workaround for me. They said they won't work together without the brushing gum and once the brushing gum is added I cannot dip with it. I know very little about glaze chemistry. Does anyone have any solution for my issue?
  4. Hello! My fellow potters in the local studio and I are looking for images of the Brent SR20 slab roller. Ours recently broke, we purchased cables, nuts and bolts from a local hardware store but we cannot figure out how to get it back to rolling the correct way. The cables broke in several parts and were all messed up when we took it apart therefore we were unable to get a good idea of how it was together in the first place. We're hoping for some pictures of the pulley system. We appreciate any help/pictures provided. Have a great day!
  5. Hi all, I've been starting to have a crawling issue with 3 of my last firings and can't figure out what's happening here (see photo). All color underneath the clear ^5 glaze is Amaco Velvet. I give 3 good layers for the underglaze every time, and have not changed the technique for painting. Glaze and clay body also remain the same. Upon suggestion from a friend I tried doing the firing SLOW, but that didn't help either. Couple of questions for you Amaco veterans: 1. Have you had issue with the crawling happening over Velvet? How did you resolve it? 2. Even in small coverage areas, the glaze is up higher where there is no underglaze, and lower where there is. A bit lost on what to do about this new strange issues.
  6. I am a novice and just purchased a secondhand Amaco 1-101 (it was very cheap, and I know that it's maybe not the best, but it's fine for now). It came with what seems to be a plaster bat (weird, right?) and I'm trying to get some other bats for it that are not plaster. It doesn't have a pin system, and the wheel head it comes with is 12" and has sides that come up and doesn't look like any wheel head I've seen before. Can anyone help me figure out what kind of bats to get to replace the plaster one I have? Thanks!
  7. Dear all, This is a rather odd post in that i am brand new to pottery and manage an art studio in a resort in the Maldives. I have received a kiln from China which is a front loading, electric machine with no pre programmed programmes.... I have amaco low fire clay (red and white) and am wondering what to input in my kiln for bisque firing. The clay is to be fired to cone 04 1077 degrees C, but im not sure on the ramp/timings? I'm really stuck with this now....there doesn't seem to be any clear info available to me online and the supplier sent me instructions on HOW to programme but not what to input (understandable). If anyone can give me a nice step by step explanation on what to input, temps, for how long (whole profile) I would be so grateful! Does anyone use the Amaco low fire clay? Many humble thanks in advance! Melissa

  9. Hi all, I've just seen that my local suppler has stock of the Amaco Crystallex brush on glazes. The specs say to fire to cone 5. I use high fire stoneware and I'm wondering if anyone could shed some light on the ramifications of firing to cone 5 instead of cone 6 as I normally do. May thanks, Andrea

  11. I'm trying to get the hang of using my Amaco hydrometer to get consistent specific gravity with my new glaze tests and also with my slip. I cant learn anything if I just keep guessing. I want consistency when it comes to "my" part and then after that the fire gets to have its say. So in glazing I get information that says glaze should be around 140 to 160 sp gr but the readings are for 1.xxx. On this scale 1.00 is even with water, nothing in it. Or on the other side it is 0-70, 0 being the reading for water. Here is a pic of what I think is the proper consistency of a Leach Temmoku glaze. It reads 1.600. I know that there are deviations depending on what type of glaze and that some need to be thicker than others but looking for a starting point really. In the Britt high fire glaze book there is no specific gravity except for some recipes that I guess are deviations from a standard? Does anyone know the standard specific gravity for this particular book? Also on the same topic when using slip for dipping and general purpose decoration like brushing what should the general specific gravity be? I seriously need to get a real drill that can mix a 5 gallon bucket of slip. Its hard doing it with a kitchen whisk ;-) Hoping the answers I get will help others along the way! Thanks everyone for your input!
  12. Hello, I am using AMACO glazes for the first time, and I need some kind advice. AMACO site shows wonderful effects when two layers of different glazes are used. I coated (brushed) the bottom part of one cup with three layers of PC20 and the second one with three layers of PC23, and trailed the top parts of each cup with three layers of PC53 with small overlap. According to the site info, I had to fire it once at 2195 deg.F with long down-fire. I programmed my kiln for 15 minutes exposure at 2195 deg.F with further down fire to 2012 deg.F for 60 min., followed by 5 minutes exposure and further cooling to 1900 deg.F within 60 min., followed by 5 min.exposure. I was not happy with the result, the colors were different from those at the AMACO site (dirty brown/yellow colors appeared in the overlap area and PC53 became unsmooth). Photographs of expected and my results are attached - the bowl is from AMACO site and the teacups are mine. Could you please advise my mistakes in applying AMACO glazes/selection of firing program? Many thanks in advance, Pavel

    This embellished angel was made with little loafers cone 6 clay. The designs were rolled into the surface and then glazed. The face was press molded with a minor hand sculpting. The hair was made with a mini extruder. The hair and face is painted with Amaco LUGs and the wings are coyote white and the dress is Coyote Opal. This angel can be used as a stand alone figurine or it can be used as a tree topper. I added holes on either side so that it can be securely anchored to the tree.

  16. Hello, I recently was given an old Amaco electric potter's wheel no. 1-101. The wheel has not been used in a long time. The wheel head does not switch to the correct direction for throwing. There is also a knocking noise when the wheel is on. I have a basic diagram of the parts and wiring that came with the wheel, but can't figure out where to begin troubleshooting the problem. Any advice will be appreciated.
