Two 4x5 plates were coated with Liquid Light. I hope. Red light was used, only one about 6 feet away. The bottle of emulsion was unpacked in red light and placed in a large Pyrex measuring cup. That in turn was filled with hot water and let sit a little bit. A two reel stainless steel developing can was also filled with hot water. A hot plate was turned on low. The glass sheets were in a 4x5 tray both on the edge and along a center ridge forming a wedge. It would have been easier to find that tray if it had been white instead of black.
The first time I tried to pour some emulsion out of the bottle nothing came out; it must melt first. It doesn't come out easy; the more that melts the easier it is. Some was poured into the stainless steel can and that was put on the now off hotplate. One sheet of glass was warmed up on the hot plate. Then, some emulsion was poured onto a glass sheet; it moved easily.
It spilled onto my pants, on the floor, on the table. Wear a plastic apron. I was sitting down for the first sheet and put a developing tray on my lap for the second try. It didn't look like it was coating the glass evenly; rather, it pooled or left holes. More was added; it spilled off into my hand; I held the glass by the sides or the corners.
Warming up the plate helped some. both plates went into a paper safe. The emulsion got sticky pretty fast.
A thorough clean up followed.
The plates are allowed to dry inside the box. I'll open it in the dark a few times to change the air inside it since it is made of plastic, but it is large.
