Hello, fellow hide glue geek. If you're not already familiar with it, here's a gem of a document called "Hide Glue in the Modern Workshop" [0]. I really like Old Brown Glue too, but shipping it from America is prohibitively expensive for me so I started cooking my own. My usual recipe is 0.2 parts urea, 1 part hide glue flakes, 1.5 parts water (by weight), heated to 60-70 degrees celsius, chilled rapidly, then heated again and chilled again (not sure why or if two heat and cooling cycles are necessary, but it works so I'm not trying to fix it). The result is indistinguishable from OBG. I have also tried the "123" recipe of 1 part table salt, 2 parts glue flakes, 3 parts water (by volume) but it inhibits the gelling too much and the drying times are too long for my taste. However, it works better than the urea recipe in cooler temperatures. I'll send an email to the address you have in your HN profile. Reply if you want to geek out about natural adhesives and woodworking in general.
