Hi Hank,
I lead a double life when it comes to glazes. At home, where I fire ^6ox,
I have the analysises (oh dear how to make that plural) for every chemical
in my stock. I have all my glazes on computer. I have a triple beam scale.
I have a pleasent place to work and interesting things to listen to. I am
well fed and content.

At the Art Centre, where the pottery director fires to ^9-10 ox, nearly
every barrel of chemicals has a label that is probably correct. The scale
is ancient and battered. And the glaze room has a bare bulb in the ceiling
and two of the windows are broken. And I am most probably hot, hungry,
thirstly and grumpy, though how that affects the glazes I don't know.
Don't get me wrong, I love the Art Centre and am eternally grateful I found
clay there, but hi tech it ain't and neither is my glaze making while on
site. So when Bev's Smile turns purple there, just think of it as the far
traveled version. ;-)

Best regards,
Dubai, UAE
