  1. that is a pretty blue, Hulk, i wish it were the color i want. tried the pale blue resulted from 2% robins egg in the clear glaze Min gave me. also 2% vivid blue. both colors were sieved through a 150 mesh screen, thanks Neil, and yet the finished tests still show dark blue specks here and there. the color is very pale, almost like a white rather than blue. the thick test looked more like a snowstorm than a sky blue. so it is back to test, test, test and the new tests will be numbered 527 and up. nobody ever told me i would test so much. thanks, piedmont. mason 6374 is ver
  2. my last few days should be a comedy movie. tomorrow is set-up for a 3 day show. i am not ready. have only known about it for 2 months or so. i will work the show on sunday so between set-up and sunday, i will NOT be available. there must be an empty hottub somewhere.
  3. violette, is the studio you find uncomfortable one where people keep their pieces wet for a long time? is the throwing water kept for days? are there barrels of water for reclaiming studio clay? is the humidity level high all the time? in your own studio you can be a rebel. work as dry as possible, keeping the place clean and dry. there is no reason a modern studio should resemble something from the middle ages. i remember walking into one in brooklyn. the floor was covered with 4 inches of clay dust. i left in a few minutes, sure i would have an asthma attack if i did not
  4. roberta, so sorry to hear of your pain, i also suggest schedule 40 plumbing pipe. there should be a size just bigger than the outside dimension of your wheel legs. a half inch bolt through the plastic pipe should hold your wheel's weight with no problems. the only tool you will need for the job is a drill and a vise to hold the pipe steady while you drill those holes straight through. i would put the bolt in at least 8 inches down so it will be more stable. if the dimension of your wheel leg is very much smaller than the diameter of the new pipe, be sure to stuff the space wit
  5. if you can, get the answer from the US post office, the kind used in their priority mail envelopes is best for what i want, no fat fibers, no texture. the manufacturers name is all that appears on the envelope, maybe someone at DuPont can identify it. if it can handle the treatment given packages in the mail, it is a great product.
  6. not every electrician is familiar with installing kiln wiring. ask for references for kiln installations and call those references. besides getting a good or bad report, you can meet other potters in the area. make sure the electrician has installed a large kiln, not just a test kiln.
  7. yes, i advise you to think about the future of the planters. i have been planting so many things in the past month that i am dizzy, none of them have gone into ceramic pots, though. they are temporarily sitting on the deck until a neighbor with a bobcat has an hour or so to drill holes for roses and trees. in almost solid red clay soil. i ain't diggin' no holes, nohow. glaze is a finish that has proven itself over centuries. find a good one that satisfies your artistic intention and works with your clay. if you haven't got one yet, start testing. there are so many possibilit
  8. hulk, the blue mugs are gorgeous. it is a really beautiful blue. i will use it some day as a bowl exterior. but, i think i will have to have my math expert neighbor figure out how to do a total of 100.
  9. wait a minute, little egg. why are you firing them to their final temperature without glaze? underglaze alone is not necessarily totally bad but do you have a real need to not glaze these things? how do you assume they will be cared for forever? they will never need cleaning, no greasy fingerprints will ever happen, nobody will think you just forgot to glaze them, etc. any photos?
  10. it is true that badly prepared items can blow up. i have had this happen once in the many years i have been single firing but i kind of suspected it was not ready for firing. just stupidity did it.
  11. sheffield has a lot of potters whose work is for sale in their showroom. well, before covid, who knows what is happening now. if you ask them if there is a potter working the same way you plan to, maybe you can find out easily. they may be able to make suggestions and even allow a sample of the ones you want to try. personally, and i think other potters here agree, i would never use a clay with such a wide range of supposed firing cones except at the highest one. i know you are only using it for slip to apply to the red but once it is in your studio, you cannot predict what will h
  12. just make sure the clay is totally dry before you put it into the kiln. fire it slowly to 1200 f as neil mentions on the way to cone 5. you do not say if this goes into your own kiln or not. might matter to the kiln owner so do not be surprised if you are refused a single firing.
  13. ok, i am going to use robin's egg blue because it DOES have zirconium (which appears to have some mysterious advantage in keeping the color more transparent than other ingredients). to have just a hint of color and as much clarity as possible, i will try 1 % and less. fortunately, a new neighbor is a math magician, taught it in many schools to students of all ages. thank you all for reminding me that there is always something new to learn about this wonderful artscience.
  14. thank you, that is what i want. i use that darker cobalt blue often but i am trying to find something more like sky blue. i will try the very tiny percentage you suggest. still would like a sky blue, though. i love the cerulean slip but the pieces i want to do in sky blue will have only glaze on them. min, is zirconium going to make the glaze transparent or are you saying those colors wont be because of the zirconium? so i am on the wrong track completely thinking opacifiers cause lack of transparency. it is melting that is important.
  15. browsing through the jan/feb 2011 issue of pottery making illustrated i found an article with info on using clay for outdoor use. did not read it but remember a fairly recent question about it. jessica knapp wrote it. find on page 6.
  16. looking for a mid-range blue for min's clear recipe that has a minimum of opacifier so it will be as clear as possible. i have cobalt carb and the following blue stains : mazerine, vivid, cerulean, robins egg, deep turquoise and zirconium vanadium blue. i also have deep orchid which has no purplish at all, comes out wishy washy blue in every test. i want to keep the glaze transparent so the feature noticed is the impressed plant material. my other glazes take away the crisp distinctions i want and flatten out the texture too much like covering with a blanket. pansy purple and the
  17. callie, i suggested a cereal box wrapped in paper and the last sheet is loose, not taped on or anything. that allows the box to be pulled out of the piece BEFORE firing. did this many times with salt boxes that became birdhouses for a kids class.
  18. check your area for a propane dealer who sells those parts. they will get you exactly what you need at a reasonable cost and even hook up all the parts so you just connect the right ends to the right place. they are very safety minded so they are the best of all alternatives.
  19. i think it would be OK. not a sculptor but have watched and read about various kinds of sculpture. i do remember an article showing a filling of bits of vermiculite inside a panty hose leg to allow pressure during construction. when finished, the stocking was torn and the vermiculite poured out. i do not think actual vermiculite is safe to use, has asbestos or something. but the idea is a good one. gumby is tapered so i wonder if you could fold slabs around a cardboard box as an armature. not thick, brown stuff, more like a cereal box. wrap it in newspaper and leave it loos
  20. victorie, this is your first test. we tell newbies to test, test, test. now you need to get a notebook for written notes showing what you did exactly so you can read it after the firing and make new additions to your notes. leave room for results when you test so you know what you did and can repeat the good and avoid the bad results. yes, hand written notes are portable and you can write them anywhere, no electronics needed.
  21. havely, are you in the guild in the old mill in hampden? you are only a short distance from the beautiful baltimore clayworks studios on smith street. there are several sculptors there who are generous with their advice. could you just go visit their studios now that maryland is open? if long life means made in 1976, i have a mirror made by barbara lane and hanging on the old kind of aluminum pop top beverage can tab. the kind that totally tore off and left almost a teardrop shaped hole. she used epoxy and covered the back with felt because of the glass edge of the mirror. excep
  22. since you are new to this, i wonder if you are aware that sculpture should not be solid. very thick clay is likely to crack because it is so difficult to dry all the way through. try getting some books from the library to add to your internet info. older ones that show how to make hollow pieces that look thick but are not. some of the older textbooks show how to build pieces that have their own "armature" built into the structure. i remember one that was a child kneeling. the interior looked a little like an old wooden beverage crate with dividers running from front to back and side
  23. welcome to the forums! i was in boonsboro yesterday buying flowers from those two nurseries and lunch at the ACT. hello, neighbor. my kiln room has a dirt floor. my daughter put down a plywood floor which has over the 18 years shifted just enough to trip me. but it works for a kiln room. alone, vinyl flooring will tear, it has no strength as a flat slab, any heavy item will press it down into the dirt and tear. if the surface is very flat, you are lucky. pavers work well if the soil is flat, if not, each edge will catch your foot and trip you as you are carrying your most val
  24. glad to hear from you. the sources of info have increased greatly in the last 50 years. the problem with some of that info is that without a solid background it is easy to think that all of it is of value. then the problem becomes, "who should i believe?" you will get good info on this forum, everyone has a specialty and you will get to know a lot if you ask questions. personally, i want to scream at some of the googled "experts" who give bad advice. once the stuff hits the internet, it cannot be removed and thousands of people think they learned something good when they d
  25. do not remember ever using sanding. damp cleaning as liam says above has worked for me since 1972. try it. i just did that with dry greenware this afternoon.
