  1. Air drying clay is very different. Suggest you buy a small pack for yourself and have a play before inflicting it on your students - lol.
  2. Yes, you can thin it down. It may be insufficiently stirred. I find the best way to "stir" slip, is to pour it from bucket to bucket at least 6 times.
  3. @Bill Kielb they're not overlaps, they're 3 different firings
  4. You can even try firing it at bisque temperature and see if it improves. There's always a risk with a re-fire, but If you're not happy with it as it is, you might as well.
  5. Size is of the mould. Different clays have different shrinkage %, so impossible to state finished size.
  6. Instead of two pieces for the main cylinder, which have to be pretty exact so they will part properly, you could do that with 3 parts, then no matter how unequal they are, it should part without tearing.
  7. Get a syringe and syphon the slip out, then drain the last few drops.
  8. As above, but I'd like to really REALLY emphasise that clay and glass were not designed to go together. Read through this forum and you will find hundreds of posts where people are having difficulties to get a good match between clay and glaze, which are designed to go together. Glass can explode away from the clay. It might not happen today or tomorrow, but might be in 6 months time. You wouldn't put petrol in a diesel-engined car. Don't mix clay and glass.
  9. My programmer is from Stafford. It's higher spec than the one at the centre which is an Ipco. Both are programmable for up and down ramps, just that the Stafford has more segments. You get what you pay for. I think almost all new UK kilns come with decent digital programmers.
  10. I'm in the UK, and have a very old Potterycrafts kiln. It's had new elements and thermocouple since I've had it. Also replaced the very basic timer with a proper programmer. It's a small top-loader. At the community centre we have a larger front-loader, don't know what brand it is, was bought from Essex Kilns. Have had no problems with it, it's about 7 years old, fired once a week most weeks. Whatever you buy, pay proper attention to what you plug/wire it into. Many here are much more knowledgeable than I am, they'll help you out when you get to that stage.
  11. Have you searched the forum? im sure this has been asked before. Also, please update your info, including country, as this is a multi-national community, and what is available in one country might not be in another .
  12. It's one of the few arts/hobbies where you can almost continually recycle the raw materials. Until you fire, of course .
  13. Could you buy 2 smaller kilns, or 1 more and keep the current one? School where I attended evening classes had 2 kilns, one programmer, and a way to switch between them. Night class mainly used smaller kiln, fired once a week, day school used larger and fired 2 or 3 times.
  14. If you do fire it hotter, use a decent saucer or cookie under it. I didn't and it melted into the brick floor of my kiln. Took a chunk of brick out when I finally got round to removing it! Needless to say, I take much more care now.
  15. Is there an on/off switch on the underside? We have a similar controller at the centre.
  16. As @Min says. Plus, if you fire to the clay temperature, it's highly likely the glaze will be undermatured, (dry, crusty).
  17. Whatever you put in it also has to be safe for skin. I can handle clay, but need to wear gloves when glazing as it dries my hands too much. I wear gloves for general domestic stuff - washing up, cleaning bathroom etc,. I would not touch clay if i thought bleach had been added to it. No other suggestions, sorry, but it's something we might all have to consider in community studios - including me. Arrrgh, will it ever end!
  18. UK Post Office has (allegedly) 5 times more post than xmas, and fewer staff as many are self-isolating. Yesterday I received a box that was posted on Tuesday last week. It traveled around 60 miles.
  19. If you don't like it as it is, you might as well chance it. I've re-fired stuff successfully, and I've had some mega fails.
  20. Yorkshire puddings. Yes, it goes really well. Don't know if this is a UK thing, but we eat pork with apple, gammon and pineapple, turkey and cranberry, blah blah blah I too love rhubarb crumble, but try not to eat too much pastry/crumble/cake. The new way of eating together is decide on a menu, cook the same, and eat at the same time, while practising social distancing, and communicating via phone, skype or similar.
  21. I put two posts at the front of the shelf, one post at centre back, then there is no post in the way at the front, and if I lean on the front of the shelf it doesn't tip.
  22. 1st rhubarb crop this year. Steamed in a sieve over other veg.
  23. I think that's a brilliant challenge. No ideas from me, but I wish you well in your quest.
