Food coloring in 'glaze paint'

So do you think the Kool-Aid glaze simply had Kool-Aid added as an
ingredient so that it was visible on the ware?

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!

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.

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 -
water )
They are 15 and 20 now

Definitely Tang (tasted like tangerine juice but I believe was entirely
artificial)... Definitely.
(once was a big fan of the space program, tang and Rainman)

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!

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!

exactly - just for visual use.

i saw a production pottery house doing typically cone 6 ware ("squash
pots" - mold & ram methods).

they used color in the glazes so the workers could tell if a product
was fully glazed or not just by looking at them. or if a batch was
left over night you could easily remember in the morning.

DKat - if you liked the space program (certainly me!) get a copy of
that Tom Hanks space series: "From Earth to the Moon". rental or buy
it. it's an excelent docu-drama.

see ya

Never heard of it. Thanks!

P.S. Have you ever been to the Smithsonian National Air and Space Museum in
D.C.? They have the Apollo space module on display. If you have never seen
it, it is really worth the trip. I cannot believe they actually survived in
this thing. It's walls look paper thin and it was incredibly tiny.

non pottery but fun anyway:

by the way - the space museums in both huntsville alabama & cape
canaveral (florida usa) are every bit as good as the one at the
smithsonian in washington DC! i was lucky to get a special tour of the
cape for a shuttle launch (VIP seats - but delayed launch. got the T
shirt though). i saw the refurbishment of the side bay rockets along
with many other non-usa-public areas.

huntsville has the 2nd skylab which they used on the ground to help
debug issues they had in space.

standing next to a saturn 5 rocket is a pretty small feeling. that
tourch did some 6 G's acceleration! they tuned the shuttle down to
around 3.5 G's after the saturn 5 was shown to be stronger then
needed...

should have collected some special dirt from some of the old launch
sites. might be some odd chemicals still around that make a good
glaze?

see ya

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?


Another approach is to add some Cobalt Oxide to the Cobalt carbonate.
The oxide is black in color and helps the carbonate show up on bisque or
glaze, as well as adding intensity to the hue.
