Rutile Wash has me thinking and the reason for this post. I have read that
a rutile wash is best on Tenmoku glazes.
I have seen it applied to MC6G glazes but nothing really stands out from
what I have read and other potter's tests that I can view online..
Waterfall brown has alot of variegation to it, like
rivulets,specckling,opacity and sometimes even crystallization to it. Looks
like a lot happens in glazes that melt a lot. It that particular glaze
(waterfall brown MC6G) it has a high boron level right? And for some reason
this boron melts Big Time at cone six. The rutile and iron seem to be where
the Magic happens to a fluid base like this.
So getting a Glaze to "dance" a potter is on a high wire balancing between
dancing and crazing if too much dancing is involved. They are dancing with
High fluxes and low expansion rates. Boron however, is an oxide, is that
right? So if that's true than most frits and gerstley borate contribute to
boron.
The magic than with boron is that it melts like a flux but forms a glass
with a really low expansion at cone ^6.
So my question, has anyone ever tried using a Boron flux instead of Lithium
carbonate in Gibby's wild rose Tenmoku? I am trying to look for a direction
in a Tenmoku glaze that has Purple or violet.
