LOADING
AND LOW TEMPERATURE DROSSING
The heavy concentration of
thick dross to the left,
a golden/brass central and the more vicious flow of
crystallizing metal to the right.
The same mass, however transferred
to a fused glass container
and tapped with a carbon rod lightly, to force the liquid metal to the
right. The very gray high dense concentrate on the left has less low
melting collecting metal as the tapping forces the more fluid and less loaded
metal to the right.
A 330g high temperature 1,800F fusion with flux button,
A low temperature re-melt, notice
the film covering the surface of the flow,
oxidation, yes, however the thin crust that develops can be scraped into a
pile of what looks like wrinkles
The re-melt shows the hard to melt
residue remaining as the low melting point
collection metal flows from the shell.
Once the collection metal flows
from the residue a condition of
none rainbow coloring is not seen, as Ag .003% was added.
