And you thought sulphur was bright yellow.

[The QCC]

I cut a small chunk of really bright yellow sulphur in half and made them into thin section slides.
The first grinding stage was with a 150 grit paper that produced a lot of sulphur dust. The dust was sprinkled into a puddle of glass glue and spread along a slide.
Thus there are three samples: a) A thin section polished down to 110 microns, b) A thin section polished down to 80 microns, c) The slide with sulphur dust.

Sulphur is so soft, the two thin sections were made in less than an hour.
What started out as bright yellow ended up a very muted yellow.

Neat. I did think sulphur was yellow

Very interesting, and good images. I would have expected sulfur to be too soft.
Good work.

My method to working with soft and porous material is to soak the object in a diluted solution of Elmer's Glass glue. When the object is removed from the solution and dried it is quite workable.
