There's toxic chemicals in my kiln!!! :o

Doing a test run of aluminum foil saggar firing tonight, results posted tomorrow morning success or failure!

Assembled reagents in the laboratory (my kitchen :D ) crumpled aluminum foil, ferric chloride, sodium chloride, iron oxide, copper carbonate, copper mesh (dish scrubber), and a "volunteer" subject; a miscast tiki pistol glazed on the inside.

One part ferric chloride was mixed with 3 parts water (add the acid to the water like you oughter, water added to the dry acid powder will react violently!) and brushed on the test subject.

The subject was wrapped in copper mesh.

I misted the foil with water in hopes of keeping the chemicals in place, sprinkled on sodium chloride, copper carbonate, and iron oxide. I added a few random pieces of cat food to include some carbon.

The foil was wrapped around the test subject and placed in the kiln. It will be brought up to 1000 degrees (about half of normal firing temp) over the next 3 hours then cool 'til morning when we will see results.

There is a two-fold desired effect; that there be cool fuming colors & designs on the piece and that the interior glaze will not be damaged
