Let them eat cake

Here is my latest pot porn for you: freshly stamp milled, slaked, and filter pressed cakes of Izumiyama porcelain. 150kg. 


Not for the faint of heart, Izumiyama is hard to work with. It is non plastic and likes to crack during drying, impossible for slab work, and deforms easily. And it costs more than twice as much as Amakusa porcelain from Kumamoto. Most porcelain artists in Arita and Imari switched to using Amakusa porcelain long ago because it’s much easier to work with, doesn’t crack, and fires whiter. 


BUT! The beauty of Izumiyama in the wood kiln is absolutely undeniable. It fires to a soft ivory white and blushes in very subtle shades of peach. The surface is deep and translucent and vitrifies as low as around 1230C. 

Tomorrow morning first thing, Peter the Pugger will be getting a major workout!

New helper in the studio

I traveled to the port at Nagasaki this morning to pick up my new studio helper, a Peter Pugger VPM-20. Once I got it home, it was a breeze to assemble and mount on the stand, and it was up and running in no time.

plugged in and ready to go

Excited to get it working, I grabbed a bucket of dry scraps and some softer clay, and started mixing. It took some time to figure out how to get what I wanted out of the machine, but I think I’ve figured things out for the most part. It really seems to need to be full to do its best work. Once I added enough material to the hopper, things really started moving along. The first pugged clay was too soft, so it got put in again with a lot of dry crushed sandstone and mixed. I just kept adding more dry sandstone until I got what I wanted.

the first time through was too soft and got run through again

I turned out still to be quite a light batch. After turning on the vacuum, pugging out the contents, then digging out the remainders from the hopper, I had a batch of almost 12kg. The beautiful thing was that because the whole batch had been de-aired, even the unpugged remainders were very easy to wedge by hand. In the past when I have mixed as much sandstone in as I did today, the clay has been largely unwedgeable by hand, being just too short and falling apart.

All clay bagged and ready to go

I think this machine and I are going to be great friends. It allows me to mix and process clays and other materials that were previously impossible to process just by hand. Oh, and it is very quiet, both the main motor and the vacuum pump are much quieter than I had been expecting.
