Good Day to All ,
Melinda ,
you can use a bunsen burner or stove connection .
I bought some castable refractory and used a
cardboard packing cylinder , to make a small
5 sectional kiln , firing to 1200 deg.c .
Designed for single ware gas firing ,
I can send you pictures if you would like to see
it .
Answers .
[ 1 ] The amber is from Iron Colouring .
[ 2 ] Ask on Clayart for the Ball Mill plans .
Pleasant day to you ,
Khaimraj

Ron:
I have a weed burner kiln that I lined with two layers of alumina wool. I
used a 55 gallon drum for this, but it could very easily be cut down to the
size you want. They key to success is the oxygen to air ratio. The weed
burner does not have an air control, so you must allow for this by using
secondary air which is drawn in where the burner enters the burner post. The
opening I made is about 6 X 9 inches. I am very careful not to get the
burner too far into the opening. If the burner tip gets too red, you need to
pull it out a bit. Also I cut a draft hole at the top about 6 X 9 inches and
I used a soft brick or two to control the updraft. This works well for Raku
temperatures and possibly higher. The bottom of the drum was also insulated
with 2 layers of 2 inch alumina wool.
Hope this helps you.
Bob
