Hello All!
I ran some tests along with my usual stuff, and a few turned out very
nice. I scanned the tiles really close-up so y'all can see what I can:
Hesselberths Floating Green ^6
30 Nephelite Syenite
21 Gerstely Borate
8 Whiting
10 Kaolin
31 Silica
ADD
2. Chrome oxide
1. Cobalt oxide
(Substitutions; I used TV-stone aka Ulexite instead of GB, and also
added 2% titanium oxide)

I'm not sure it's "supposed to" look like this, but it does and
I'm
really pleased. The bare spots are a result of my ppo application
technique, not because the glaze does anything weird. The scan is
enlarged about 400%.

Caution, this one runs off any vertical surface even at ^6. I only
use this for flat surfaces. Love the crackle and the colour, though.
Enlarged about 800%.

Commercial Red Effect Glaze ^6

This one usually turns a murky maroonish brown, but on this piece, it
turned orange. It never turns red, which it really should. I'm sure
this one contains sumething really really bad, so I only use it for
tiles for coasters. Do people eat from coasters? Lable says it does
not require warning label. Still...

Hi Theresa,
This is not my glaze. It is on my web site only because it was leach
tested (by Diane Woloshyn) and she agreed to let me make the results
public. I don't know the originator of this glaze--maybe someone else
does.
Regards,
John
