    Bisque/Glaze Firings

    Is there any advantage to leaving a vessel unglazed? I did try this and found that the surface scratched very easily. How could I avoid this happening? I did glaze the inside, my thinking being that if the vessel were to be used for food purposes then it would be food safe. I do like the look of a matt unglazed surface. A pic of a local potter's bowl is attached. Thanks
  2. Morning everyone, Just realized that I seem to always post on a Sunday morning lol. My question is: how can I apply luster with a smooth continuous line. Mine always has a blob at the start, peters out and then another blob when I reload the brush. Many thanks Have a great Sunday.
  3. Good morning to you all, I'm having a great deal of difficulty with getting my glazing right. A year ago everything was fine, I had a back op last October and have had problems ever since then. Took a break from throwing but came back in Feb, since then I've had one hand done for CTS and the other is on it's way to being done. Since the op my sciatic nerve has been damaged so I have problems with throwing, and indeed pain is probably one factor that is affecting my glazing. I was making forms that were hand built tall vases, glazing became a problem due to the length of time it takes to fill the vessel, put down the jug and then empty the vessel (splashing glaze every where). This done my insides are always too thick leading to major crawling. Was glazing the outside by dipping half and half (top and bottom), leading to thickness around the overlap, Did rub down, but still came up with spots of milky glaze. Now the next step. I used Amaco PC brush on glaze for two new projects, the one has milky streaks and crawling. It was fired stoneware, bisqued to 1000deg C, Glazed to 1200. The glazes used indicate cone 5-6. They were set on the floor of a small kiln (no elements under it). It is possible that at that position the heatwork was not enough (cone did not bend). What should I do now? Refire and raise the vessel to higher point, and what about the crawling, should I try to glaze those spots or should I make a decorative feature by using luster? Give up and rethrow? Thanks for listening On the other hand, what would underglazed but not glazed work do for me?

      Nice indeed!

  8. I really need some help with the mixing of high fire glazes and medium. I have these 2 urns and my plan was to have a shiny white interior (stoneware 1200° C) interior with Amaco brush on on the outside, I've done the inside firing to 1200 with a 20min hold. My problem is that the interior has crawled badly so I thought I'd put crushed glass into it and refire, but having already fired to 1200 will the Amaco glazes actually work? TIA Andrea

    Did I get it wrong

    Yes Babs, I'm a real idiot. I don't know how my train of thought got so wrong. I've seen vids where reglazing is done, but I don't think they were originally fired to cone 8. I was going to use the Amaco glazes and fire to cone 5. Since there is major crawling inside and one of the lids has cracked I think it is not even worth trying. I may just use one of them as a test at some stage just for curiosity.
  10. I use a chamios leather to stick bats to the wheel. My wheel does not have bat pins and throwing a pad is too much effort. The chamios works exceptionally well allowing easy removal and you never have to do the clay pad again
  11. Hi, I have a couple of glazes made up and I want to be able to brush on as I'm having difficulty dipping. How so I do this? Many thanks Best regards Andrea
  12. Hi everyone, I did try and find a solution but only came up with how to change the glaze composition. I have two urn which I just fired and both have crazing. I checked thick6of the glaze and all seemed fine. It's stoneware fired to 1200°C with 20 min hold. I've had problems making these pieces and it's taken me 8 months due to health issues and trying different forms for the request. Can I refire and hope that the glaze will smooth out or touch up with glaze and refire? Solutions would be much appreciated. Many thanks Andrea

    How can I fix a crazed pot

    Sorry my problem is brain as well as crawling lol

    Critical firing temperatures

    Thank you so much for this information. A concise complete explanation of the firing process that I much needed.
  15. Hi everyone, Some help please. I'm trying to make spooze and can not find corn syrup. Can I use glucose instead? Many thanks Andrea
  16. Quick question. I have a bone dry piece that has a clean brake. Can I join using sodium silicate? TIA regards Andrea
  17. Hi, I want to make a slab of pop for wedging. How thick should the plaster be so that it doesn't crack? I want to make a wooden frame and fill with plaster. Thanks in advance. Have a good week Andrea
  18. Hi everyone, It's been a while! My mother-in-law passed lst year, straight after I had a spinal fusion. My sister-in-law asked me to make an urn for her ashes. This was 3 months after the op. It's now been 8 months and I've just had Carpel Tunnel Release in my right hand and my left is due to be done in 2 months. My problem is that they are getting a tad inpatient with the delay. So here's what I've tried (unsucccessfuly)... Throwing (came out too small), Slabbing into a bisque form and joining two of them, slabbing around a pvc pipe (couldn't stretch it without cracking), coiling, this has been my latest attempt. Coiling has never been a strong part of my work but now doubely difficult due to the CTS (my hand has now taken a lot of strain), they keep turning into bowls. My thoughts today were to slip cast into a bisque mold and join two of them, remove the top and bottom adding a foot and opening where I can form a lid. Problem .. thickness, the altering part, the pouring and using a bisque mold. I'd love to create a really elegant piece to honor her memory. Suggestions please.. TIA Andrea

    Making an Urn, Help

    Gaby, as long as you use a couple of sheets of newspaper the pipe will slide out easily and you don't leave the clay on the form until leather hard, just until it is firm enough to stand on its own. This way the clay hasn't shrunk right down against the pipe. Also by using the wrapping you don't have the clay pulling away and hanging if you know what I mean. Once I've wrapped the clay around the pipe and before wrapping the sheet around it, I smooth down the form, getting rid of any canvas marks. I really go to town with a soft rib and sponge. The advantage of the sheet is that it draws off a fair bit of the water I've used to smooth down the clay. Rolling the tube around on the canvas/sheet has the added advantage of compressing the clay. Hope this makes sense. None of the studios that I have been to has used thus method and in fact until I first did this I didn't have any success forming vessels.

    Making an Urn, Help

    Hey peps, Thanks for taking the time to reply. Here's what I've now done. It's still at the hard leather hard stage and I'm forming the lid, which will dome upwards. Gaby - you don't need to start with such a big piece of clay. I've made several standing vases standing 17". What you do is : using a pvc pipe wrapped with newspaper for easier removal, roll the slab, wrap around the pipe, roll the whole thing onto a sheet which you wrap around firmly. Then roll the whole lot in a piece of foam I've used craft foam and an old yoga mat cut in half. secure this with a couple of thick elastic bands. You can now pick up the whole lot and carry it around, stand it up or lay it down. Because of the support from the sheet and rubber there is no stress on the clay and it keeps it's shape. Pres - I want to apply a white slip to the box, should I use porcelain casting slip or just porcelain slip? and at what stage should I apply it? Thanks all, have a good day. Andrea

    Latest fails as of 05.31.18

    My instructor showed a method where you put a funnel of paper around the top of the mug so that the glaze pours out evenly and reduces the dripping There is a post on the daily section where there is a cheat using pvc piping angle joints and a sponge attached for the inside of the mug I've yet to try this but I'm sure that this would work fantastically. I have trouble getting an even line when I dip. Getting better takes time and lots of fails. Best of luck and stick at it. Andrea
  22. What you need to look at is what type of underglaze (if you are going to go that route) and what glaze you'll be using. That pretty much dictates what you can use. You say that there's not much decorated work with colour, then you should work towards that. It gives you an opening where the market is. Also think hard about the length of time it will take for decoration. If you want to go the route of complicated patterns you'll lose out on the quantity. So quantity vs quality, that's the question. Little pieces are quicker sellers in a world economy where luxury items are concerned. Ceramics are mostly thought of as a luxury most will not pay for. So you're really on your own here as you only know what your economy is. Good luck and may your efforts be rewarded.
  23. Good Morning everyone, I'm considering moving from stoneware to earthenware and I would like your reasons for your throwing preference. Thank you and have a good Wednesday

    Underglaze versus glaze?

    Hi Min, I've done the underglaze blend fire to maturity but found that on one piece a scratch developed which wasn't there after firing. Apart from glazing with a matt how do I go about protecting the surface?
  25. Hi peps, I've had an idea for a box for my daughter. She's a complete bookworm and works for a publishing house. I want to handbuild the box. Sloping top carved to outline a couple of books. How do I go about attaching hinges to it? Or should I rather make it a lift off lid? Thanks and my you reside in your potting space for the weekend. Andrea
