Here’s the liquid hide glue recipe I’ve been using the past few years. It's really easy... It requires three ingredients and three minutes.
1 oz 192 gram strength hide glue granules
.2 oz Urea Prills
1.5 oz distilled water.
To mix, simply place a small glass jar on your scale and tare it out. Add your granules followed by the urea. I give these a quick stir and then add the water.
Once the three ingredients are poured, I stir it together well and cover it to leave it sit overnight.
I often make a double batch but I would not advise making a batch larger than you will be using up in a few weeks. The fresher the better.
I know Don Williams uses and recommends canning salt instead of urea. I have tried this but have to play around a little more to find the right ratio of salt for what I like. Don told me once that the urea can potentially cause a problem in the glue down the road. (Titebond and Old Brown Glue are both urea depressed however.) Don, if you’re reading, can you enlighten us as to what the potential issue with urea specifically was? If I find the right ratio I will be sure to post about it as the canning salt is way cheaper and more readily available than urea prills. (Unless there is some supplier I am not aware of.)
