  1. What's on my workbench? Another trip down the rabbit hole. First tested these glazes in 2014 in an electric kiln. Gave up as they didn't mature at ^6, and no-one else fires that high and I can't produce enough "test tiles" to fill the kiln. Off to a wood-firing next weekend, so decided to make some more tests and re-hydrate those glazes. I'll say hello to the mad-hatter and the rabbit from you all while I'm down there. Middle photo are some tubes for testing, bottom is "posh" catcher trays to stand the tubes in. Then we'll only have to wad the bottom of the trays, not all the tubes.

    Slipcasting

    No release agent for plaster moulds, that I know of. Have you checked that the mould is clean? Try vinegar and a sponge to clean it up. Does your slip release easily from other moulds? Are you leaving it too long before un-moulding? Too little time? Casting too thick, too thin? Small curved moulds are the devil to deal with. I have had to enlarge the "funnel" on handle moulds as they never held enough "top-up" slip.

    Glaze on bonsai pot foot

    To get a fully glazed foot, (going back to the original question), you can stand the body of the pot on "things" that raise it above the shelf. Shelf posts, small pieces of broken kiln shelf. So long as the pot is well supported, not just in the middle, it might not slump, and then you can have fully glazed feet. I've done this several times, but beware that the pot can slump if not properly supported, and if the glaze runs it will drip straight onto the shelf, so catchers under the foot are useful. This is not one of my pots, but something I'd love to create some time.

    Kiln not reaching temperature

    Mine slows down after it gets to about 1100c. So probably yes. I have a smaller kiln than yours, also a Potterycrafts, with the same max temp. Even with brand new elements it struggles to reach 1260, but will put ^6 down with enough heat work. Have you opened the kiln yet? Was the firing OK? If it fired for 18 hours, your pots are probably overfired. Did you use cones?

    Kiln not reaching temperature

    That kiln's max temp is 1300c, so it should get there. However, unless the elements are in excellent (think new) condition, and you have a very short cable and are plugged into a socket that goes direct to the fuse board it is highly unlikely to reach that. Are you using cones to judge the firing? If it has been firing for longer than you expected, it could have fired "enough" to mature your glazes, but you will only know that from the end result or from cones..

    Sculpture stuck to base

    Goggles are great if you can wear them, I struggle with the fit, so I wear safety glasses over my seeing glasses and have a face shield as well. Feel like a space man when I'm dremelling.

    Will it break/crack when firing ?

    There are two problems: Uneven thickness can cause cracking while drying. Keep it covered with plastic so it can dry very (very) slowly. If it survives, the next problem is the firing. The solid parts will likely still be damp, even if the surface is dry. As moisture evaporates from the surface, the moisture left in the thick parts has further and further to travel to escape, and the outer surface is shrinking, making it harder and harder for the moisture to escape. It is moisture left inside the thick parts of the clay that causes explosions. When you fire it, take it very slow to 100C, hold it there for some time for the moisture to warm up and evporate, then take the temperature up slowly for another 100C, then fire as normal. Be warned that if it does explode it could destroy everything on the same shelf, and may even damage pots on other shelves. Good Luck

    Diamond disc, as @Mark C. says. I also have a diamond blade for my dremel for small jobs. Plus dust mask

    Therefore, it is highly likely it was slipcast, so could be the mark of the original designer or the factory or ...................

    yarn bowl dilemma

    Have you tried an earthenware glaze, and fire them in with your bisque firings?

    Bisque/Glaze Firings

    How thick were they? Did they have enclosed hollow areas?

    Bisque/Glaze Firings

    When you say you don't need to do anything, does that mean you are not glazing them?

    Hannahs Blue Fake Ash Glaze

    Could an admin please correct the typo in the title of this thread, otherwise it won't be found in future searches for "blue". Many thanks.
  17. The frames were purchased, not made by me. I did the embroidery, and the other half put the backs on, probably 25+ years ago. No idea, but possibly used hot melt or two part glue. They don't look like they'll come off in a hurry!
  18. Or you make the frame like this, where the glass and picture sit behind the frame and the rebate is on the back. This has a padded embroidery, so no glass, but if you use acrylic instead of glass it might be more flexible.
  19. If your client sees something they like, and you want to sell it, and they are prepared to pay x for it, say thank you. People with money will pay for something they like, because they like it, not because they think it's worth it.

    Armatures

    Welcome to the forums. Every question comes with lots more questions in reply: How big? What clay? What firing temperature? It might be better to make it solid(ish) and then to make a mould from it, then slip-cast a final item. That way you get a horse that is uniform thickness, without worrying about armatures, or hollowing out, uneven thickness - which will affect drying and firing...........

    Kilns - new or second hand?

    Do not use an extension lead. Either move the kiln or get a qualified electrician to put in a socket direct wired from your fuseboard. Yes, I learnt that from experience, luckily I noticed soon enough that the plug/socket were melting together!

    Plaster for wedging table

    +1 to above comments. And Put your long sleeved rubber gloves on before you start measuring, then when you need to plunge your hands into the bucket, you can do so without risk. Plaster can be irritating to skin. I don't use a mixer or stirrer, only my gloved hands, that way I can feel for lumps and know it is properly mixed.
  23. Suggestion: Is it worth it? Several threads recently have asked is it worth........... Be good to see a discussion in it's own thread on the general pros and cons of fixing, restoring, recovering, making your own. So many things to consider: time, cost, environment......
