  1. Unfortunately my CRC chemistry handbook doesn't get a lot of use these days other than as a weight to press things! Interesting topic so I'll lurk around in the background ( plus I work with terrasig for my smoke fired pottery and I'm just getting into slip casting. The particle stacking makes sense in thin, low SG terrasig as it buffs up nice. ) Are you looking at variation in temperature during the making of the terrasig ? You need to talk to Tony Hansen, and the person he's quoting in this article about terrasig: https://digitalfire.com/4sight/education/super-refined_terra_
  2. Thanks Mark! I'll slow things down a bit to make sure things are cured and then coat them with whatever I can find to seal them hard. Polyurethane from the hardware store. And I'll check out the axner product.
  3. I'm still working with mold making. The course I took went by fast & we worked with a plaster lathe, made models, used soap as a release (Murphy's oil soap) and then made molds. This worked pretty well but I'm having problems on my own now with the soap release. I tried spray Pam- ok for the containers but 50% or less success with plaster models releasing from plaster molds. I try to take things apart relatively quickly- should I wait longer ? Use a different release soap or spray??? Trying to get this all worked out before I move on to larger items and its so frustrating. Just watching
  4. I just bought 2 of Akira's mugs before Christmas, then had to get two more as every time I went to the cupboard my husband already had them in use . They're my favourite!
  5. Is this the stuff with a pool of clear glaze at the bottom of a bowl? Just looked at the original post & that's what I thought it was. Too bad it splinters!
  6. Small world! A lot of anthems of my youth - scaring myself to look at the videos on you tube now though - all the grey hair - yikes we all got old!
  7. Sadly these days- not music! Podcasts : Marketplace, Planet Money, the Indicator, Science Friday, ...(sometimes Fresh Air ) If I do put on music its usually heavily tilted towards Oscar Peterson, then Deadmau5, Dyalla, Eddie Harris & Les McCann, Herbie Hancock, Moby, Thelonius Monk, The Byrds, Eric Burden & the Animals
  8. A lot of pit fired work is bisqued to a low temperature such as 017. I've bisqued to 04, then pit-fired the pottery and am still happy with my results - its all trial and error to see what you like. Forgot to mention - my stuff isn't vitrified - just decorative.
  9. I agree with this and i just built one recently. I have to make a modification though. Currently, we just raise and lower the top part with a pulley system. I'd like to change this to a winch so that I can fire it more easily myself.
  10. Oh! I just saw that at a local cooking store and carried it around for awhile trying to decide if I wanted to try it with clay or not- now I know- thanks !
  11. Because of the ease of creating ice models from various types of molds in our climate, many people experiment with this. An extreme end member of this activity is ice carving competitions and ice "hotels". The less experienced artists use ice molds - homemade or purchased silicone molds. You've probably seen the floating ice centre pieces used in punch bowls or the ice lanterns along walkways into homes. Plaster mold making is a new-ish thing for me and I like to see what is possible while learning how to use this material. This making process has me veering into all the interesting poss
  12. Ah ha! I was thinking about that- doing a skim coat but the trick would be to get it on evenly. I should contact her about this. Looks like I'd better soak some paper .
  13. Cottle boards are used and I have some, but this item is bigger than my boards , so I've had to find something else. Just picked up some crazy carpets at the hardware store - (the kid's tobogganing plastic sheets). They are stiff enough to form a wall around my model.
  14. I don't know about airfare but our dollar is in the tank right now - floating upside down. So things would be cheap for you on this side of the border. Have to sort out the process though. The ice would melt & maybe with some crazy shapes! Maybe a process where I can get the hardening rate of the plaster to be a tad faster than the melt. More hair brained ideas to keep me experimenting
  15. Will do. New Year- New Project I even considered using an ice form as the model but first things first- get the basic process done.
  16. Sounds like I should try a slightly wider mold - have to go check out the hardware store for flashing or a crazy carpet. I'll keep the buckets for slip. One more question : will paper-plaster mix leave holes where the paper slurry bits are? I'm also trying to reduce the weight of this thing. But I have to keep the mold surface smooth, so that is another decision to make before the store opens next Tuesday - Calgary is such a one horse town - no instant gratification here!
  17. the drying instructions are pretty important from the looks of it. The plaster course I took last summer was at the height of the heat and the fans were going like mad. Looks like I have to try to replicate that.
  18. depends on how well the mold comes out! I'm not thinking about how many yet- just trying to get 1! So are you inplying that hydrocal will last longer???
  19. I am making a large mold using one of those large plastic buckets that you get from the hardware store. The model fits well except it only has about an inch around the sides for one small portion. I have heard that hydrocal (plaster w a bit of portland cement) is stronger than pottery plaster No.1 and I'm wondering if I should use this because of the thin area. Anyone know? Does it adsorb the casting slip as well as pottery plaster No.1? (The store that sells it isn't open 'till Jan8 so I can mull it over till then.)
  20. Mold Making continues - now to clean up the mess :(

  21. been trying some mold making. Think I prefer the wheel.

      Your wheel work is outstanding from what I can see on your Instagram site. I like the Raku yarn bowls and tea light holders in particular because I've gotten requests for both recently. Your work is an inspiration for me! As for the mold making, like anything else in ceramics, there is a definite learning curve. It's just a matter of whether or not you want to spend the time on that side road of your journey...

      Thank you ! Got up this morning and had a look at yesterday's disaster & thought of another way to tackle it. You're right about time and having to just do it to learn.

      Mold making for me is not as immediate as wheel throwing. I make lots of mugs, each a little different even thought they start with same amount of clay. Making all the same would be boring on the wheel, but mold making not so much if I could get through the first part to the second part. However, I am not really interested in going with all the slip casting process.




  22. My neighbour was an artist and I used to sit for hours watching him paint on weekend mornings. That was a pretty young age for me - likely 8 or 9. He was also a sculptor. I remember trying to make things similar to his work with our back yard mud - wonder if he noticed? The school system I was in (public) invested in art education. We were always on field trips across the river to the Detroit Institute of Arts or Cranbrook or on a train up to Stratford or something! Most people have no idea what a great area & incubator for art the Detroit area was - thank God they saved the DIA whe
