The foot control not jumping from zero to 88mph when you barely touch it, good bat pins and the rest I don't care about, although I'm spoiled by the quiet nature of my Bailey, it's really grown on me and now all the wheels at the studio suck, lol.

Pop said catawampus (an' a few other things, ahem).
Also cattywampus. Origin of catawampus
1830–40 for earlier sense “utterly”; cata- diagonally (see cater-cornered) + -wampus, perhaps akin to wampish Dictionary.com Unabridged Based on the Random House Unabridged Dictionary, © Random House, Inc. 2019

My wheel is a Bailey that I got about 20 years ago. It is my 4th studio wheel since 1971. It is slower than Brents. I like that. Most important to me is the control of the form. I have been throwing some larger orbs. I had several go catty-wompus (sp?). I took them off the wheel, jiggled them to straighten and hung them out until they stiffened a bit. Then put them back on the wheel and and continued throwing. I do give up on some and just re-wedge them. Very excited about my new work with soluble salts.

If you have other stains available it would be a good idea to run tests with the other colors. Change only one thing at a time so you can nail down the effect of each different variation. If you get the same hazing with the different stains, then go to the ball clay and start over with the brown. Your other option would be to use the ball clay with the brown stain and see what effect you get...if the hazing goes away, you'll know it's your clay. Good luck with your testing

I think in the tea ceremony the cups are not set down for any length of time after filling, they are kept in the hand, cleared and washed immediately. Not really enough time for seepage.
Maybe I'm picky, but reheating coffee in the microwave for a whole minute on high seems excessive and makes the coffee taste awful. 30-40 seconds should be plenty, unless it's a Big Mug, imho.

What about those wares, that were glazed with radioactive materials (Fiestaware)! When it comes to getting the colors we want, potters will use about anything!
Also, in regards to the doughnuts, Whew, I was worried for a second. I forgot that donuts, are something COMPLETELY different. Doughnuts are basically health food!
terrim8 reacted to Min in raku tea cup - food safe?
Were they raku or faux raku? There is a potter in my area who makes ware that looks like raku but it's a stoneware or porcelain body with a white crackle glaze on the outside that's been stained. Not saying that the raku tea cups you saw weren't raku but as others have said it wouldn't be a good idea. Think we've all probably seen pots that make us cringe due to inappropriate glazes on wares intended for food use.
re doughnuts: I think we're okay Ben, Mea was talking about donuts not doughnuts, phew!

Someone has to be bringing him to class. The school could probably fill you in on more due to safety issues. I agree with Lee about the safety issue - as long as he's not near the kilns or anything else hazardous then he will be fine and its a good thing for people to help him out - good for them and good for him. He won't be with you for long as S.Dean said above . Unfortunately my Mom is going thru this now - she's 96 and she's taking part in activities to keep her mobile. Actually the care home's version of pottery is just the paint on type and my Mom would not have done this when she was younger & healthy. She used to go clubs with jazz music, travel all over Canada & the US, enjoy going out to dinner, shows, racetracks, boating, etc - she'd roll her eyes about painting flower pots if she was still herself. She still laughs at jokes - try that with him instead of being so serious
( think I've told this story before - if so please ignore!)
terrim8 reacted to Mark C. in raku tea cup - food safe?
My friend brought me a raku mug a few months from southern Mexico. It has a clear glaze inside. I lead tested it and it came up zero. The main issue with it is it weeps-. If you fill it with watewr the clay body over a pretty short time frame will get wet. The tip of handle is the last point to saturate.
If one was to use it for drinks whatever you are drinking slowly seeps into the clay body-milk-juice -tea ,whatever. I see it as unusable except for water-and for that you need to pay attentention putting it down as that surface will be getting wet.
Maybe we westerners pay to much attention to this but I really do not like weeping pots.
In terms of hurting one with any poisions ,I do not feel thats the case at all
its more of a nappy clay full of organics from the fluids. In some cultures this may be a desired deal just not in mine.
terrim8 reacted to Callie Beller Diesel in raku tea cup - food safe?
The Raku tea bowl is one of those places where context matters as far as food safety goes.
Making a Eurocentric style coffee or tea cup in either Japanese or North American raku styles is going to result in an impractical piece because of how people expect to be able to use it. In both cases they're underfired, there's thermal shock fractures, the glazes are soluble, and in some cases the colours are fugitive if not sealed against the air and oxidation. It's not going to stand up over time to daily hand washing, never mind the dishwasher or microwave. The object itself isn't going to hold up to that kind of use. If you run it through the dishwasher on the sterilize cycle, pull it out and use for coffee the next morning, get distracted by the kids, find it an hour later, put it in the microwave for a minute.... pop goes the cuppa. Maybe not the first time, but I've done that with a stoneware cup that was just cracked, never mind something that is a lot less structurally sound.
In a tea ceremony, the whole thing is about being present, and in the moment, and about savouring the whole experience. There's a mindfulness and a sense of care that just isn't in that last scenario.
terrim8 reacted to Magnolia Mud Research in raku tea cup - food safe?
I have used commercial low fire glazes on raku without the reduction step in the trash bin. The glaze looks like regular earthenware. They should hold water ok. Never used as drinking ware,but probably just as good as earthenware. My understanding of the Japanese process fires to higher temperatures which means lower porosity.
Test and see. The American raku glazes are most likely not stable in some drinkable liquids, so glaze studies would be needed.
l have fired some ware to cone 10 with a liner glaze and then refired to raku temps with raku glaze on outside; proved it worked, became bored and moved on to more interesting challenges.
terrim8 reacted to liambesaw in raku tea cup - food safe?
They're porous in Japan too. I don't think most people use raku for tea ceremonies though, my inlaws have tea bowls that are locally made and appear to be high fired stoneware.
The Chinese use yixing ware similarly, the idea is that the tea that is absorbed into the body helps condition the teapot or tea bowl and it becomes even better over time.
terrim8 reacted to oldlady in raku tea cup - food safe?
exactly. not confused. i am trying to find out the difference. i know that only tea is used in the tea ceremony and that the cups are not in daily use. i am trying to find out what makes the original, true raku, able to hold water, (tea) without leaking all over the user. i know that the usual raku pieces made here are absolutely not useful for holding anything wet. what is the difference in manufacturing them that makes them so different from each other.

Its interesting to watch your progress. My walls & arch were all double thickness and the front and back walls were fit into the arch - lots of brick cutting and getting the angles right. I agree with Mark- you'll need to squeeze it to the arch. It's a shock to see the wall bulging out as you reach cone 10. Steel support is a good idea. What did you decide about a door?
terrim8 reacted to Marcia Selsor in new saggar and obvara pieces
I have been busy with firing pieces for several exhibitions since the weather broke. The obvara was pretty successful. I have been experimenting in the saggars using tiles as baffles to help hold combustibles in place. I am including two pieces of framed baffles because I find them so intriguing. the pots range from 8-12" in ht. I am using terra sig on the sagger pieces as well as on the smooth areas of the obvara pieces. I use ball clay TS so that it absorbs the obvara and the fuming in the saggars. I just added the poster for the Invitational show.
terrim8 got a reaction from Stephen in Reputation for selling cheap pottery
Seems like a lot people are struggling with this topic right now. Elon is trying to figure out how to make his Model 3 less expensive. Apple is realizing that $1000 is a bit much for a cell phone. Heath Ceramics has an outlet in Sausalito with seconds at a lower price. Wish I had their problems!
I haven't got the energy to sell 1000 pots for $1! So its try to make things well, try to make them attractive and try to figure out the market as I go.

My cat doesn't have any steel or other framing. The back and doorframe are stacked so that they "cork" - interior course sits inside the kiln, tied into the exterior course which overlaps the opening. They do spread a bit during firing. Initially, we extended the castable overcoat over the seam, but that was a terrible idea because it crumbled during the firings at maximum spread and the bits fell into the fiery chasm, never to be retrieved and making some of the spread permanent. The spread never opened as deep as the "cork," a brick's width, but worried some spectators when exuding flames at ^10. Wheeee!
Arch was rebuilt from hard to soft brick, but the doorway and back remain hardbrick. Margins are now covered by the layer of fiber beneath some pretty sheet brass (scavenged).
I'm saving a soft brick door and frame scavenged from another kiln for a possible rehab, replacing the back and doorway with softbrick and tying it all together with a real door and steel frame. The cat is really too big for me to fill by myself, so that project will wait.
terrim8 reacted to oldlady in Used fire brick changed my plans
just thinking about a PBS documentary showing the rust belt in USA. patrick, you are not far from larger cities where there are probably many older buildings that have steel that would simplify your door construction. there is probably an architectural salvage company that can locate what you need. spending a little now to save your back in the future sounds like a possible solution that would involve something like the Medalta structure. smaller but sturdy.
terrim8 reacted to Mark C. in Used fire brick changed my plans
Catenary walls (back and front) like to move out and away from arch over time so some steel in place can fix this flaw.
A note about loading-a kneeling pad works great. I had a huge cat at home for about 10 years(1973 to 83) and always kept a pillow around for getting inside to load the back wall.I built a well insulated car kiln in 79 and never fired the cat again -it was like yours -all hard brick and cost mega $$$ to fire.
The car kiln made my life about 1000 times easier on the back and wallet.
