If you purchased full sized 72" / 1,82 m glass you should have enough to make a sample limb.
Rip some maple stock 4mm thick and 3,81cm wide same length as the leftovers of your glass. Glue it up and put it in a vise, with a 10" or larger visegrip pliers on the other end. Hang a 5 gallon bucket filled with 45# of sand weighed on a scale will give you a ball park thickness of your sal bending. Compare it to the sal bend in the mock up 8 post above this post.
