In hi-school...my friend 'Bob', who was liable to get a mite
'bored' on occasion...put a ('Police type') can of 'mace' in
the little Ceramic Kiln as was IN the 'Art-Class'...
Well...when they brought 'er up to 'heat', that aerosol
'can' went...and they had to evacuate that 'wing'...
Ol' (young) 'Bob'...!

I absolutely would NOTNOTNOTNOTNOT use a spray deodorant in
raku. Clearly
on any kind of aerosol can you almost always see the words
DO NOT USE NEAR
FIRE OR FLAME. HelLOOOOOO!, that's a clue. It means: THIS
CAN WILL
EXPLODE UNDER EXTREME HEAT CONDITIONS. Raku definitely
qualifies as an
extreme heat condition.
Now, given that, what would be the purpose of depositing
aluminum or
alumina? on the raku piece?

I used deodorant after raku,instead of shower because we are short of water :-)
It is art but the deodorant is flame-able and blow up-able!

Steven,
Whaaaaa? Sorry, could you explain exactly what you mean? After I had
stopped laughing at the mental images this produced, I still couldnt
understand how, or indeed why anyone should have thought to do this, but if
you do do it, can we see the pictures please...
Best Wishes
Pat.

I don't know about raku, but I do a lot of saggar firing, and I know in a
saggar firing anti-persperant/deodorant only leaves a white chalky spot...no
color.

thanks ababi for a good laugh!!!
on the other hand, i`m sure someone will find out
that deodorant will give a killer color or a gorgeous halo
or something else...in raku...
please post a picture after testing, we wanna see it!

Hi. I am not sure if anyone mentioned this already....... but the
propellant for many spray-type products is often a flamable gas. So
spraying it on a red hot raku piece might result in a little "blow torch"=
effect. So be careful.
Has anyone tried post-reduction of raku using a roll-on deodorant or
better yet a stick or spray to deposit aluminum on the surface?
Best,

I have been using hairspray for years as the propellant
in my potato cannon, the cheaper it is the more power
it has!

If I understand your question correctly, you want to reduce an
aluminum compound to get metalic aluminum on the surface of a raku
piece.
If that is what you are trying to do, you are going to be disappointed.
The short answer is, that is not possible from a chemical point of
view.
Raku reduction is a chemical process in which you expose a metalic
salt to another compound that is *so* reactive that the new compound
steals away oxygen or other elements from the metalic salt- leaving
only bare metal. If the metalic salt is in a glaze, and everything is
just right, the glaze will harden with the bare metal in it,
"freezing" the effect. (A metalic looking glaze.)
The problem with aluminum is that it is so reactive that there is no
other compound that can steal the oxygen away from it.
