The Ultimate Glue Test (hide glue)

More details and photos here: http://fixitwithshading.com/2015/08/02/the-ultimate-glue-test/

This is a little test where we mix 8 different thicknesses of hide glue, join 8 pairs of wood, and break them.

The glues tested range from 11% to 39% glue by mass.

PLEASE NOTE: During the break test, the amounts read out as "by water" should be "total mass (glue + water)." The actual amounts used in the test are as according to the chart of glue ratios from the earlier section.

This is brought to you by students of the Chicago School of Violin Making.
