This article is a quite interesting read. What jumped out at me was the mention
that different colors of ABS have different specific gravities (within a small
overall range). I wonder if the saline solution would have a detrimental effect
on the surface quality of parts. Might be an interesting way to sort your pcs by
color. Also might make a neat & non-jugemental way to code colors (by the
specific gravity).
