I am thinking about putting food coloring in my glazes to differentiate
between two that are very similar color in their natural state. Does
anyone know of any problems with doing this? Effects on the glaze
slop?
I appreciate any info.

Kurt Weiser told me that he had his glaze book stolen when he was a
student. In it was a glaze called Blue Koolaid. Blue Koolaid's recipe
contained the usual ingredients, feldspar whiting and the like, but at
the bottom of the list was 1 package blue koolaid. I can't help but think
that this must have give the glaze a blue color. I wouldn't want my
glazes to taste good so I wouldn't give it a try.
Several years later Kurt was giving a workshop on the west coast and a
student said, " hey, we've got a sheet with some great glazes on it, you
want a copy?" This was all from Kurts book, last on the list was blue
koolaid.

You shouldn't have any problems with food coloring in your glaze, as it will
fire out . This is what they do to clear glaze so that you can see where you
have applied it. "What I do with clear is to actually put food coloring in
after the first coat to make sure that I don't leave any thin areas.

I've done this for several years and haven't experienced any problems. It
also alerts you any missed spots on the bisque. Easy to miss 'em when
glazing a white glaze on a white bisque.

I have used food coloring for 4 to 5 years with no ill effects to the
glazes. For a 30,000 gram glaze batch I have found it take 2 large bottles
and you frequently have to add more to the glazeas it is used up. A
definite benefit if you have pots that don't make it into the kiln the first
time around. Nothing is worse then that chip on a unfired glaze pot that
you can't tell what glaze to put on it.

Another good use for food coloring that I picked up from Pete Pinnell at a
workshop this past summer is to use it for drawing out patterns on a piece
to follow when slip trailing, hole cutting, etc. It completely burns off in
the bisque.

artist-in residence with Paul Soldner at Iowa State University.

India Ink also works well for drawing or making notes on already glazed
pieces for later decoration. Burns off nicely.

I find it helpful to tint the second coat of a three coat brush
applied glaze with food coloring so I can tell where I've been.
Many times on a large pot with surface detail requiring careful,
(therefor slow) application, the glaze dries to fast to let me
know how many coats are in place. This color burns out and in no
way tints the fired glaze.
