In the UK standard domestic rubber gloves (Yellow Marigolds) are Nitrile. Latex Rubber Gloves (I call them condom gloves - the sort you see doctors wear) are insufficient. The Selenium can penatrate Latex but not Nitrile Rubber. Selenium can be absobed through the skin. Its hard to work out just how hazardous the stuff is - as almost everything is classified as hazardous. I top up my solution of Selenium Toner, adding 16ccs after each 12x16 print. I found by adding small amounts as I went I eliminated down stream problems with the emulsion flaking off during Gold Toning. I now do the continuous top-up scheme, whether I Gold Tone or not.

Thanks for the tip about topping up. I think I'm going to use that idea - it seems to make sense.
I am really liking how the density changes but I have to say that the purplish tones are not to my liking so I am still experimenting but will likely gravitate towards very dilute ratios. Gold toning is next on my list! |

Indeed, Ilford FB toned in selenium + sulfit goes eggplant colour. Very unattractive to my eye.

Oddly enough, this could be a good thing to do. Selenium is an essential element in the human diet, and soil levels appear to be falling due to intensive farming practices. So, diluting used selenium toner (which is going to be pretty depleted in selenium itself, unless used one shot), and watering the soil (not the plants themselves) could be a positive boost to ones selenium intake.
