barium in raky glazes?

'Lo, all!
There's a bulletin/display board in my studio which bears cut-outs from
Ceramics Monthly of clay pieces I really like for whatever reason(s). One
cutout shows two pieces: the bottom one is a large raku urn creditted to
Robert Hasselle; the one above it doesn't credit the artist, but is called
"Reliquary Vessel", is 42"H, and covered by a beautiful blue glaze called
Barium Matte Glaze -- and looks like it, too, is raku.
After a couple of years, this has sunk in. Good thing it wasn't a
snake.
Didn't know that barium could be used in raku, if indeed this is a
Hasselle raku piece. Can someone help me out here? If there is such a
beast, I'd sure like to whip up a batch...
Tenk you,

anne & the cats

Hi Anne, this is the only raku glaze I've seen with barium carbonate: its
name is Middlebrook's Crackle White. 60% gerstley borate, 50% potash
feldspar, 22% barium carbonate, 16% silica. It is from Pipenburg's book,
Raku Pottery. Let me know how you like it...We're going to try this firing
again Wednesday next. We're too old to take up needlepoint. Lori in New Port
