    Flat Brushable ^6 + glaze

    Thanks preeta. I do some sagar firings as well and my whole approach is all about the most direct process sans the regimented routine of making. I like that the video shows him working directly with the wet clay, and I assume he's using TS or some sort of underglaze. Nice.

    ...throw ten 10" cylinders all the same size in one sitting...kidding, I'm just kidding... :)

    Emulating other people's work

    IMO it's healthy to see a piece of art, whether clay, paint, or any other medium and think "I wonder if I could make that?"... It seeds ingenuity to see and try. A challenge is always a good thing...

    Flat Brushable ^6 + glaze

    They look like a good choice. The representative swatches show a matt/gloss sample. I'm wondering if the gloss represents them fired under a clear glaze...are they matt out of the bottle and fire matt?

    Flat Brushable ^6 + glaze

    No, don't need food safe specificallly, strickly art pieces, at least on the outside. I can use something else in the quiver for inside glazing. Strong color is a bonus! Where do you go to buy a pallet of underglazes Neil?
  6. Being originally a painter first, I'm looking at doing some 'painterly' pieces next time around. I want something that can spread like paint and ends up a flat or semi-flat and opaque. Think 'house paint'. I'll be firing to at least ^6. I've used some of the ^5 Laguna Versa glazes but not where I want to go surface -wise. A base glaze that I could add colorants to or even a commercial type suggestion would help... (Linda Styles) example:

    If one of your students....

    It takes all kinds. The fact that you're doing a favor to the community by teaching private lessons in your own home is reason enough for people to behave. Maybe the person in question is deteriorating from age, then the response for me would be to 'Have a Laugh" about the situation and then move on. Otherwise I would have just told her that she was welcome to leave any time she wished...

    New Skutt wheel issues

    Gotta say I'm loving my new Legend. I finally got out there and a threw a bunch of cylinders. This thing is smooth and as quiet as can be. (non-SSX drive) BTW, I did put a couple nose suppressors on the plug and peddle and my FM interference is gone. Ahhhh!...

    Gas kiln stalled . Why?

    Usually when a kiln stalls at the top of the schedule, it's not always obvious that it needs adjustment. You might just stare and say "Huh?" I agree with the others on needing more air and/or more draw through the flue. The schedule looks good, but yes, by 1000 degrees you can advance easily 100-200 degrees an hour by adjusting both your gas and air. The flame needs to be burning all the fuel with as much air as required to bring the flame to max heat. Adjusting the flue is key as well. You don't want all your heat going up the chimney, but just enough to keep the temp on course.

    Where do you put freshly thrown pieces?

    Due to the fact that I work outside, I use your standard Home Depot-like steel shelves and wrap them in plastic making them waterproof and create a good drying cabinet of sorts. The front plastic cobvering the 'door' is just a flap I can flip up on top when using the shelf. I 'close' it and can secure it with simple hardware clamps. In the morning, after I throw a dozen pieces that I set on a close shelf or cart, I'll transfer them to the drying shelves. I can easily monitor how fast the dry depending the outside temperature. I can normally take a 2-4 hour break and go back and trim in the afternoon.

    Olympic gas kiln - to buy or not to buy?

    Don't get me wrong. I wouldn't recommend these to newbies expecting their commercial glazes to come out like the photo on the website. To get this hot box to fire evenly is nearly impossible. That said, It's fine for the potter that wants to experiment with all things clay and glaze, (like me). Just don't expect it to do a nice controlled even burn. It needs close attention. Yeah, it will reach cone 10, probably 12. Heck I've slumped some clay in it... Reduction? It's actually tricky to get it NOT to reduce.

    slab mat

    You mean the paper/fiber type? I've used mine for two years and they're still in good shape.

    Bailey 22" Mini Might II Table Roller

    I had the Mini 16" roller, worked well to get me started. Way easier than breaking your back trying to roll out a biggish slab with a rolling pin, believe me. There is enough work in just preparing the clay for the roller, that's all I care to do by hand. The Mini is very handy (and priced well), but it should actually be secured to a bench so it doesn't move around when cranking the clay through. I just sold mine to a student this week. Glad to say I have a big table nodel 30" Bailey now...

    Olympic gas kiln - to buy or not to buy?

    I have one and agree as said by others, this little hot box is very hard to fire evenly. Always hot on the bottom, at least a cone hotter. If you need precise coneage for say a commercial glaze, forget it. I wouldn't recommend one for a beginner. If you've had experience in firing gas kilns it's still a challenge. For me I've resigned it for doing bisques and crazy reduction firings where everything is an experiment in the kiln. I've had to modify and experiment with making target bricks, kiln shelf configurations, and firing schedules to get even close to a even firing. It's real finnicky and needs to be babied and watched closely. That temp will rise very quickly, and even in a bisque can blow up pieces easily.
