I was a horder of materials in my mid carreer so I have all the tin I need back when I used a lot and it was cheap and buying 1 ton of Gerstley was dumb luck long ago and thats what is in my white liner which we use a lot of these days . Now days I never worry about price of materials if I need it I order it.

Full Shelves or Half Shelves in Electric Kilns
Mark C. replied to HenryBurlingame's topic in Equipment Use and Repair
I like a full shelve on bottom in an electric supported at all stilt point off floor . With advancers you have two options one is kilnshelve.com the other is Bailey ceramics which are the same as advancers but usually alot cheaper. I have over 50 advancers in my gas kilns (selling 24 extra of these now on potters web) these are all 12x 24. I started testing Bailey Germany made advancers (not called that) years ago ands they are the exact same shelve only the corners are more rounded. I bought last fall 20 14x 28 from Bailey (about 7k) and have fired them in 13 glaze fires to cone 11 and as the others are super flat -thin and pay for themselves in space right away. Consider them the same as any advancer. The deal with any of these shelves is the shipping pack up charges as that can add 30% to cost. Bailey came out way cheaper on that as well. -

Photos of the inside would help but my guess is this a glass annealing kiln by the looks of shape and handle on lid.That means its not for ceramics. This brand I think is pretty old-call Alpha Fired Arts in Sac and ask abouit when they went out of business as well as what type og kilns they made.- 15 replies

vacuum recycled clay to remove air pockets
Mark C. replied to philmid's topic in Studio Operations and Making Work
All good pug mills use vacuum systems but it works as the clay is being beat up with a screw during that process exposing the air under vacuum. The bowl I do not think will have any effect. Wedging will remove them if done right -

I only use Brent wheels -I have a model A (1/3hp) for trimming and Model B (1/3 hp) and a model C 1/2hp to thrpw and a CXC for throwing .They use IR and I like it. I cannot imangine not having it. I have demonstrated on a whisper shimpo and it was super quiet but I could stall it with medium size clay and a load on it. I would never as a pro have one. Its a great beginner or lite use demo wheel. I'm a brent fan and yes they make noise but its never been an issue as I like music and hear it fine and can talk just fine while throwing. I have zero red skutt experience.

HP rating are not all the same -that said 1/2hp is usually enough for all size pots one could ever what to make. The 1/3 hp is a bit weak for larger work

Reitz Green without Gerstley Borate?
Mark C. replied to davidh4976's topic in Clay and Glaze Chemistry
Gillespie borate is still around at some places as well as Custar-just need to look harder and stock up. IMCO in Sacramento Ca has the gellespie for cheap cost -
Clay recommendations for wheel thrown sculptural work
Mark C. replied to tman123's topic in Studio Operations and Making Work
If you are firing in the cone 10 range and these clay items are just sculpture then Laguna's WSO is the most forgiving clay I have ever found.I feel Bmix with grog is not your best sculpture clay no matter what temp range-get a more loose body It's more like a cement feel than clay and very tough to crack. I made a 3 foot wall fish from it and it came out fine spanning 3 -12x24 kilns shelves on a waster slab -
Got a notice about this thru a few sources. Laguna has 2-3 other choices with Mahavir Feldspar being the go to Hard to say if this is permanent or will change again-if You like custar and need custar buy oit now while you can find it.-Last call
