First glance though the clear is a bit cloudy and the Albany gold stuff is fine but the new clear im testing is cloudy too. Maybe just too thick. Don’t know if it crazed or not but if it’s not clear doesn’t really matter if it crazed

I really really want to use the local clay company (still 150 miles away in Austin) vs buying Laguna B-mix which I’ve always loved because $22 vs $38 per bag, mainly due to freight. Going to try out the other Texas maker - trinity - next when we visit DFW soon.

If it’s gonna ping it’s gonna ping
Looks like hit a solid 6 on top #ceramics #pottery #holidayKilnOpening

Well kitten clear apparently does not need two coats

On the blue it’s better but it seems that blue runs if the glaze is thick

This is fine; happy with carvings, glaze pretty good. A worthy Xmas gift for MIL.

Note this is cinco blanco clay and pinging like heck. The other bowls are b mix and are not. Beginning to think cinco blanco just is terrible

Next level - solid 6. More of the same on the red bowls (cloudy). Temp appears to have been consistent top to bottom. Brown mugs darker than I thought they’d be but we’ll see how the sides look. Bottom test tiles also super cloudy. Light blue bowl glaze is clumpy and cloudy. Looks like the low COE glaze needs to be thinner and dipped not brushed.

Rest of shelf - another nice blue bowl and more ok reds

Thick thin glaze very apparent. Also this blue says go easy on the clear. More tests needed TBH.
Show thread3Jane Tessier AshpoolDec 21
Test pieces of low COE (coefficient of expansion) glaze. No apparent crazing! But thickness clearly problematic.

Very consistent heat throughout kiln

Ok last photo. Three leaf mugs! Darker than I hoped but good. Good sister gift. #ceramics #pottery #holidayKilnOpening

I’ve only fired this kiln maybe six times so I’m not in “trust” mode yet.

@3janeTA

it's lovely!! 🍂

ha my stuff pings all the time, but that's bc i open at 1000°c 😂

@moonrabbit mine are utilitarian so I need to worry about it a bit more. I would not open before like 200 personally, though we pushed it to 450ish at college.

@3janeTA

@3janeTA I hate that pinging. Sigh.

@LJ right now it’s just that darn white clay I’ve been fighting with!
Show threadLJDec 21
@3janeTA I'm trying to convince our studio to replace our bmix with a white that has a lower absorption rate, but I dread trying to find one that fits all our glazes.
Show thread3Jane Tessier AshpoolDec 21
@LJ my bmix is doing way better than the white I have and I’ve always loved it.
Show threadLJDec 21
@3janeTA I'm seeing a lot of late crazing with bmix. Typically after a year of use. My thinking is it's absorbing tiny amounts of water in the dishwasher over time & making the clay expand. My favorite clay is 90, but it's brown & not great for using underglazes with. But it has such a low absorption rate that it never shows late crazing.
Show thread3Jane Tessier AshpoolDec 21
@LJ if I had a good white slip I’d flip and use brown clay with white in top but also that sounds ridiculous. But this sgraffito thing and majolica are kind of my space. I’m not as much into cone 10 earthy glaze effects anymore.
Show thread3Jane Tessier AshpoolDec 21
@LJ I do have some crazing with the bmix it’s just so much less!
Show thread3Jane Tessier AshpoolDec 21
@LJ I thought there would be challenges getting my home studio going but did not anticipate glaze fit/low COE clay body to be the foremost!
