Old brown glue is the original liquid hide glue. Formulated and produced by professional furniture restorer Patrick Edwards in Utah and sold as a sideline to the main family business, it is the same stuff that they use every day in the workshop.
The mainstream glue manufacturers now produce similar products, but we place great value the tradition of craftspeople sharing knowledge and making things for each other, so here it is, carefully handmade in small batches using the finest quality ingredients available.
It's very good stuff, traditional hide glue without the glue pot. Just stand the bottle in hot tap water for a few minutes and it's ready for use.
