I’m still working on equipment to start making mercury developed daguerreotypes. Today I glued up the laser-cut acrylic plate holders for my mercury pot. These holders sit between the dual darkslides and hold the plates during development One holds up to four sixth plates and the other holds up to four of my self-named 35 mm “mini-plates”. Each plate window has a fitted closure so the plate openings can be closed off if not needed. More blue tape engineering to keep them in place when used. A small gallery has a very few kind of hard to see photos.
Also this weekend I put into service a mercury vapor analyzer that I picked up on eBay. This will allow me to sample the air in my lab periodically to ensure that my fume hood is working properly. Safety first.
