No selenium toner in Indiana!

It's a sad day, I need some selenium toner PRONTO! An the three biggest full service camera shops in Indiana no longer stock selenium toner. Purdue Chemistry stores does not have selenium sulfide so I can do a home brew.

Be sure to heed all MSDS information if you are looking to make selenium toner from selenium sulfide.

It is finely dispersed powder, and has a very low LD-50.

I mix selenium powder under a fume hood (actually the inlet to the whole house heat recovery ventilator that draws at the fixer end of my darkroom sink), while wearing nitrile gloves, a lab coat and a a respirator with good filters.

The area get wiped down afterwards, and the lab coat and rags get their own trip though the washing machine right after I do this.

The up side is that the toner can last a very long time once mixed, and can be re-used to exhaustion.

After that I partially evaporate it to cut volume, and hand it in at my HHW depot.
