In MMD 991114, Hans van Oost wrote that, after immersing a pot of hide
glue in boiling water for six hours, "... the glue took more than eight
hours to gel after six hours of heating, and more than two days to gel
after twelve hours heating, so it seems to be possible to make a 'cold
hot hide glue'".

Later, he writes, "After fifteen minutes the cold hot hide glue started
to gel on wood (not in the glue pot)."

I'm confused.  Did the glue require eight hours, or only fifteen minutes
to gel?

Also, Hans' observations seem contrary to the generally held assumption
that subjecting hide glue to boiling temperatures for any extended
period severely weakens its shear strength.  Is this not so?
