In Topic: Firing A Sculpture With Aluminum Alloy Armature Wire Inside?

04 February 2015 - 08:06 PM

if the wire is all connected together and is sticking out so that it is exposed to the atmosphere, you might be able to just melt it out and let it oxidixe without blowing anything apart.

Put a good layer of kiln wash on your shelves and bring it slowly up to around 1300F. This is above the melting point but below the boiling point. So all that should be happening is oxidation to the oxide , which is inert.

hold it ther for a couple of hours. Thin sheets or wires of aluminum oxidize quickly. That should melt/oxidize out the aluminum and give the clay enough strength to re- fire it after the aluminum has oxidized out.


It's worth a try.... any other way you will probably lose the sculpter.

You can probably fire some small clay pendants or buttons. that might be fun. I have used an old enameling kiln to do this. Give it a try. Roll out some clay about a 1/8 - 3/16 inch thick, poke a hole close to the top and maybe stamp a pattern in it cut it to the shapes and size you want.

let it dry out good and paint the front with  low fire glaze and bring the temperture up.. slowly if you can...to where the glaze gets shiny. then let it cool.


If this works, also try raku!

In Topic: Our First Show ...

You can never tell what you will sell. I sold half as much at a $10 local afternoon show at the local shopping center as I did at the well publicised $250 studio tour. Next time I did the local show I sold only $75...


It's in the lap of the (kiln) gods...

If it walks like a duck, and quacks like a duck, then it is a duck... this is closer to a duck than a kiln.

I don't care about functionality, stability, or anything like

that; I just want something interesting to happen.



Try some frit 3134 and sodium silicate ... maybe 50/50.. who knows... just a guess. Throw in a half a percent  ( 0.5%) cobalt carb.


Paint it on with a brush till thick, either on leather hard clay or bone dry.


Paint the shelf it is to be on with large amounts of kiln wash ( it might run) . put the piece on a ceramic tripod. Fire.... You will probably get someting interesting.


Whatever you do, let us know what happened, post the results and pictures.


What you are doing is ceramics at it's best. Long live blue sky experimentation!
