Spring 2007 - Glaze Tests

Using last semester's line blend test as a starting point, this work will test the
results of combining two colorants from the previous test in varying ratios.

While making test pots, one was made to replace the lost #11 from last semester.

Hmmm -- well -- what did I learn?!

1) Even though I thought I was pretty careful about measuring the water, it looks like
dilution and its effects on coating thickness are quite significant. Perhaps in the
future, letting the piece dry and adding a second coat would be a good idea (although
it would further complicate and drag out the time required). The previous test was
about color mixtures, not concentrations, and probably less affected by these variables.

2) While making all the different shapes was fun/instructive/good practice, it is tedious
to try and glaze some of them in the rather small sample quantities of glaze. Maybe
small, straight-sided cylinders would be a better idea -- even if less fun!

3) In the future, it would be interesting to try some different ratios of these two colorants,
and also perhaps some adjustments in the lustre of the glaze (the current semi-matte was intentional).
