Food coloring in 'glaze paint'

I want students to be able to see the 'blue' they are painting on with
cobalt. Has anyone played with adding food coloring to cobalt?

Well I posted too soon. I had thought my search on clayart archives had
come up empty. It hadn't. More info there than I would have thought. It
seems that food coloring is used for more reasons than I had in mind
including being able to seen where the white glaze on white clay has been
applied (so I guess the answer is that yes it does burn out ok.... but then
there was a post of "blue Kool-Aid" glaze whose recipe called for blue
Kool-Aid....

What the hell is in Kool-Aid then. Thats scary.
I have used food colouring in brush wax and latex, you're right, just burns
out fine.

I use a resist that is clear, but you can get a packet of blue dye from
the clay supply store to put in it so you can see where you put it.
I have no idea what is in it, but it is very strong and burns out.

Kool-Aid is, as I remember, the drink of the astronauts - ie. powder added
to water to make a nice drink. But blue??? I've been out of the loop for a
while, I see! Hehe!

is that "kool-aid" as in "teh electric kool-aid acid tests?? Maybe they
didn't need the extra mileage ingredient, it was just the blue dye....

'Realism is seductive because once you have accepted the reasonable
notion that you should base your actions on reality, you are too often
led to accept, without much questioning, someone else's version of what
that reality is. It is a crucial act of independent thinking to be
skeptical of someone else's description of reality.'-

Exactly! Glad we never gave our kids bug juice (our name for Kool-aid)
though I had more than my fair share of it as a kid - that could explain a
lot.

Never had Kool-Aid but as a kid we had high sugar cordial some of the time.
I gave my kids juice some of the time, but mostly they drank - wait for it -

They are 15 and 20 now

Don't recall astronauts and Kool-Aid. Could you be thinking of Tang?
That was supposed to be something like freeze-dried orange juice.
Probably tasted a lot better when the nearest orange tree was
hundreds of miles below!

In certain situations we are asked about colouring materials to aid
identity and we always recommend food colours, which because of their
use are non-toxic and burn out without trace.
For example we sell a colloidal silica for spraying onto Ceramic Fibre
to harden the surface against degradation by gas, oil, or wood flame.
This comes as a clear liquid, so without a dye in it, it is virtually
impossible to see where you've sprayed.
I first came across this when our kids when to a party where ALL the
food was dyed green. Unsurprisingly not a lot of it was eaten!
