Urea and Hot Hide Glue

[John Dewey]

The bag of urea I got from Pianotek says "Add up to 15% by dry weight to
hide glue crystals, to increase glue working time."

List,

What is the formula for adding Urea to Hot Hide Glue to
increase its work time?  I realize I can do this by trial and error
but if someone has something that works before tomorrow
afternoon...

Thanks
