I will miss them-it's Leslie's too right? I used to pick up things at Leslie's in Berkeley, then they moved to Richmond and joined up with Aftosa - I used to buy a lot of odd sized kiln posts and put them in my carry on luggage (and stains that were on sale) for customs to inspect coming back home to Canada
. Gave them something interesting to do.

Gary forces the migration with some sort of solution. Your work looks so nice! I like the low temp part too

I have a bunch of clay disks drying between planks right now. I can use kiln wash too, right?(never heard of alumina wax- is it alumina hydrate and cold wax?)
-
Anything else? Such as use the same type of clay or any other tips???

Hopefully if they're on the flat waster, on a flat shelf, it won't warp!

Thanks! That's what I wanted to hear- the voice of experience!!!

Hi,
I want to fire a bowl on its rim and not get any distortion - is using a waster how this is done?

We'll be covering several firing processes using ceramic sagger and foil sagger because it protects the kilns from contamination. I sometimes fire without saggers in my own kilns. Here are some examples of soluble salts in low temperatures. We will explore color development and using protective gloves. The course is limited to intermediate and advanced students with some ceramic chemistry knowledge. Course size is limited to 12 and is 25% booked already. If interested, please register soon to guarantee a spot. My 2 workshops in the UK are sold out already.

Are the dark haloes on some of the pots (esp.the green at the bottom) produced in a similar manner as the high temperature haloes on Gary Holt's work with southern ice?
-
I have Arne's book too and I've visited Gary Holt in Berkeley to see his beautiful high temp work on southern ice. But I'm interested in the low T work too. Gary didn't toss anything down the drain- when I was there he advised me to wear protective clothing, mask & goggles & gloves..... and work in a ventilated area and make very, very small amounts solutions - only what you would use up on your project.
The problem for me is getting the ingredients - a few are somewhat easy to obtain but in Canada most are too difficult to get unless you are a commercial lab.
So far I've made a few things with polar ice at cone 6 but the lower T processes seem really interesting - you'll have to post results!
Any skiers on the hill yet? I've started an exercise program to get these old bones moving for winter!

My cats and dogs come in and visit regularly. My studio is in a overside 2 car garage of the laundry room. It is very quiet here and I work in peace. I am posting a photo of a hanging pot drying to stein up and continue to form. It is a funny technique but I have saved some larger porcelain pots this way. It takes a few hours. I continue working on other pots while a clapping one regains it's strength!

How does it fire afterwards? Any odd warping or anything???
-
Thanks for the ideas! I'm trying it again with a new big mold.

Hi all!
I am slip casting a large one piece item. It is drying pretty slowly. Is it best to dry it upside down on some sticks to prop it up for air circulation or just leave it right side up?
-
Sure those are commercial glazes? Everything looks matte and the pigments are so concentrated- looks like sprayed over resists many times - I like it! Looks like I have to make more test tiles and try some undergazes- over glazes
-
I use a tile sealer on some of my raku work- it dries invisibly.
-
I was working with cotton linters & Polar Ice last year and left some cotton linters mush in a bucket. It's still wet, mushy & white - no smell. Wonder if there's preservative in it?
-
A few of us at a shared studio are thinking about building a wood fired kiln. We also want to also use it for salt or soda firings. We have access to some free wood from a mill down the road
I thought I'd see what designs people like, pros,cons,etc .
Comments, thoughts???
The 300 cubic ft John Thies one looks nice.

Have to hurry up and make a vessel for my fresh cherry brandy mix then. The cherries are still green so I've got about 4 or 5 weeks. It doesn't have to ferment but its an excuse to make a nice vessel.
6000 years ago making wine! That was an interesting article.

with regard to halloysite in Canada:
Callie - true- its not mined here
& Ive been frustrated for years because I know where there is some, same geologic setting as the NZ deposit except its not right on the coast for handy-dandy extraction, processing & shipping. Can't get the area I know about going due to lack of funding for initial exploration work.
I've heard rumors about a possible deposit in Idaho but nothing in production yet.
If I ever get a chance to be back in the area that I know about I will grab a big bucket full.

- Very paranoid about Silico…
- hoping the copy/paste stays as is

I read a few other tech blogs & when I first saw this my mind finished the sentence differently than intended

I think a lot of the popular art right now is people feeling like they have to either make something so awful it's adorable or overly shocking/dark/depressed, and then wittiness seems to underly a lot of these themes.
Thats definitely pigeonholing an entire two decades of art into a tiny narrow beam, but from what I see as popular it is usually some depressing theme, with a witty political message or something that purposely looks like vintage kitsch.
I'm not a huge fan, but I do understand it and why it is popular. People be upset.
Maybe a name could be the period of unrest or discomfort.
It's tiring isn't it!

you probably already have this book but just in case.....https://www.amazon.com/Kiln-Book-Frederick-L-Olsen/dp/0812221869
prob lots of answers in there
I used to have a gas burner ca ternary arch brick kiln and i had to reduce the size of the flue opening - a friend helped me - I probably should have read the book!
-
I will check it out & post results - thanks!

Anyone know of a good brand or type of polish for smoked pottery that is non-yellowing? Closest I've found so far is Pledge but it doesn't produce a high shine. Beeswax is really yellow (surprise, surprise) and floor paste wax causes the white parts of the terrasig to go yellow too

Firing green ware straight to cone6
in Clay and Glaze Chemistry
Posted · Edited by terrim8 · Report reply
I used to do this a lot in my outdoor gas kiln. It is correct to use a glaze with a significant quantity of clay in the recipe. Just go by the book- slow warm up - (its called candling) even overnight then start the regular firing in the morning. I used recipes specifically for once firing - some even went on as a slip right after trimming. Dry things really well. Everything has to shrink and fit together at the same rate.
