Really like the Cornus pot, and yes, a full bloom Oncidium would be glorious.
Thanks Leo. I’m just getting ready to go back into ceramics mode. I haven’t finished the glazing on it yet from last year 😱. Looking forward to working on new stuff !!

Good! I really look forward to seeing what you make. Your photo series was really instructional and inspiring.

WOWZA! Looks great. Did you use a light coating of clear as a glaze or a stain? Looks like there is a slight sheen, but still "unglazed" per se.

I have been invited to put some pots into the Universities train kiln for a wood firing. A train kiln is very similar to an anagama wood kiln but more efficient with both time and the amount of wood it takes to fire (24 hour). The wood ash actually becomes part of the surface color of the pot. Temperatures can get to >13. These pot are made from a porcelain designed to take the heat and get good color flashing. The first pot doesn't have a hole in it. I will be posting the firing process and pots when they're done at a previous thread https://www.bonsainut.com/threads/ashes-to-ashes-pots-to-pots.12922/ . You may find it an interesting process.

I call it my fake soda firing surface. There is a thin coat of 50/50 soda ash/borax sprayed on top of a thin coat of a velvet underglaze.

That's exciting, I've recently been looking into wood firing and the effects on glaze. Good luck with the firing!

Ah yes soda ash. One of my favorite tricks. I’ve found it a little unpredictable in a good way. Always some nice surprises. Thanks. I’ve not tried the 50 50 soda ash borax. Interesting.

Have you guys ever tried this ?
Egyptian paste body [ Behrens formula base ]
adapted for hard use. temperature range - 875 to 983 deg.C
Body is hand built on a banding wheel.
Then when finished popped into a kiln on low,
dried and fired.

80 % sand and a very plastic clay , Soda bic.

The clay is immune to the alkalinity. Builds like a dream.
Effect is a river stone gloss and it is waterproof.

Used for decorative vases, and small bonsai pots.
A slight variation and will also make teapots, tea cups.

Beautiful work Abcarve.
Good Day
Anthony


just a touch of cobalt.

Sounds interesting. Not really into mixing clay bodies. Too easy to buy what you want. Started foolin’ with grolleg porcelain. Yikes is it weird stuff.

@ABCarve ,

ha ha ha, that is exactly why we don;t buy clay bodies.
North East Trinidad, off white clay - bone china and porcelain mixes
Central - yellow to caput mortuum 1180 deg.C earthenwares
South - super plastic clays.

Passed through 325 to 600 mesh if need be.

Trinidad is one big lump of clay types.

Plus we make our own glazes from oxides [ mole mole ]
and ball mill completely fired glass as glaze powder.
ClayArt was the second forum joined in 98 or so.
IBC was the first.

Anyhow, love watching you guys work.
Good Day
Anthony
