Edouard,
Titaniun (rutile) is very refractory. Victor Babu makes very large
porcelain platters with lots of time put in glazing the interiors of his
pieces. If you would look at the interior of his bottom of the platter
within the foot ring you will see a fairly large tanish yellow area
where he applied a circle of rutile by brushing it on. It is fairly
thin, but not as thin as a typical wash. He has done that to prevent
the piece in the center from possible sticking if the platter draws down
and touches the shelf in the glaze fire. This technique is not new....it
was used by ancient Chinese potters. I personally use no kiln wash on my
shelves. I sprinkle a thin coat on Kyanite on the shelves to allow the
piece to shrink without sticking and warping a platter. I use my glazes
very close to the shelf and don't have any runs from my pots. If potters
use unusually runny glazes look at what potters do that use crystalline
glazes. Another solution is to make small pancakes of clay , larger the
foot of the pot and put kiln wash on it. The glaze may run but if it
does it won't affect the kiln shelf.=3D20

Has abybody ever tried to use it as
