Mike, I think USA shinos tend to have fewer faults, partially
because our tastes in glazes tend to be pretty pedestrian, but also
because ours tend to be a little more complicated (Japanese are
primarily feldspar and sometimes a little clay.)

Admittedly, I'm not familiar with most American shino glazes, but in
some of the recipes I've just reviewed, there doesn't seem to be
anything more insidious than a bit of iron, what purpose would a leach
test serve, other than maybe shedding some light on glaze durability?
