Refire from last week. Only additional MiracleGro was added on top of the prior steel wool orange and black sawdust finish. MiracleGro went yellow instead of the blue from the first fire.

 

Note the white patch in the second photo.  In the first fire a heavy black carbon deposit was in that area.  The second fire removed the carbon, but new color did not replace it.  We have seen that same effect with a piece of Ken Marvel's horsehair pottery that was then refired in a saggar.  The horsehair lines turned white in the second fire.

MiracleGro, steel wool. Still problems with crusties from the steel wool being fluxed by the MiracleGro, but without the steel wool I don’t get any color.

Porcelain clay pot with ball clay terra sig. 1 tablespoon rock salt, course steel wool, 2 tablespoons copper carb, 2 tablespoons copper sulphate placed at each "corner" of the saggar none touching the pot. One inch of sawdust was then added then bamboo leaves and branches to fill the saggar (loosely packed).

 

Photo to be posted shortly

This dish and the test pieces were all fired in the same saggar.  The test pices show the difference between textured pieces and burnished pieces in the same saggar.

TEST TILE:

Piece wapped in Boraxo (borax sold as soap) and a paper towel.  Nice peach color & glossy.  However, is sealed the piece tightly to the bottom of the saggar.
