Min .... Does the Galloway recipe feel like other commercial porcelains you have used?
Thats a hard question to answer. It seems that the clay manufacturers have different definitions of what a porcelain is. The Galloway body throws well but is not translucent. I didn't find it any pickier with handles, warping or S cracks etc than the non translucent commercial bodies I have used. It is much easier to throw than the translucent english grolleg or New Zealand kaolin bodies I tried.The bowl below is Galloway, the lighting was dim, the bowl is actually whiter than shows in the pic.
Did you have to use low expansion clear?
The clear I use is:
G1215U plus nepsy
EP Kaolin 14.00
Frit 3249 20.00
Nepheline Syenite 2.00
You can easily tweek the expansion by increasing or decreasing the nepsy. One caveat with this (or any low expansion glaze), don't use it on the inside of a pot with with a high expansion on the outside, dunting / shivering risk. If you don't have Ferro 3249 then there are alternate recipes on the Digitalfire website.
I used 200 mesh silica in the Galloway body.
