Dear Cat,
Sawdust:
Use terra sig made with the infamous TSP
Bisque at ^012-09
You can put rock salt and copper carb in layers with sawdust sticks and
newspaper in a can with a few holes in it. I use a can with 12 holes at
four per level on an oil drum. Peipenburg starts the flame with a
propane torch at the bottom. I have tried it this way and it works
great. For additional coloring you can
1. color terra sig with mason stains
2. soak bisque pots in ferric chloride or copper chloride solution and
keep your hands out of it and don't breathe fumes..
3. put some of the above in the sawdust next to pots.
Make sure the lid is on and the fire is attended through the night-or
that it is a safe place where a sudden wind won't blow cinders/embers
anywhere causing a fire.
DUNG Firing
bisque 012-09 for keeping the burnished surface.
1. dig a hole about 18"-2 ' deep with a ledge about 1/2 way or more down
that will hold a grate to sit the pots on.
2. start a fire on the bottom and let the coals build up. you can line
the pots along the edge of the pit to dry them out and preheat.
3. when there is a good bed of coals, place the grate on the ledge. put
pots on the grate upside down.
4. cover wih dung so the pile is a foot ot two above ground level.Lean
metal sheets on top and sides. Maria Martinez used old license plates. I
have used metal siding scraps
5. wait for the fire to ignite on the surface (sometime two or more
hours of smoldering)
6. cover with ash when the fire is dying down. This helps blackness.
(laing with a little horse dung helps with the blackness)
Have fun,
Marcia
