I swore I'd never do this, but:
The students where I have just started teaching are nearing the bottom of
their favorite glaze, called Multi-blue, and of course the recipe is
nowhere to be found. I've got a few ideas for testing - it looks like a
Cone 10 reduction version of Floating Blue, but with a touch of copper
red added - probably a combination of cobalt, rutile and copper. Unlike
a lot of rutile blues it doesn't run significantly. Anyway, I'm going
to begin work on it this weekend, but just in case the recipe is out
there in the public domain, I thought I'd ask you folks.
DISCLAIMER:
My free e-mail service doesn't permit me to do things like surf and check
the archives, and I have searched a bunch of books and magazines - so
don't get ticked off, please!
Thanks for your help!

>From an older Ceramics Monthly, can't remeber which issue:
Multi Blue Cone 10R (however also works at Cone 6R)
Custer Spar 384
Strontium Carbonate 85.5 (original recipe called for Barium Carb.
Whiting 114
Gerstley Borate 70
Magnesium Carbonate 31.5
EPK 59
Silica 259
+Copper Carb. 15
+Rutile 39
Results: Shiney green - blue on its own, but turns all sorts of
wonderful blues over other glazes, doesn't run unless very thick.
Hope this sounds like your missing recipe.
