Storing Curved Windshields... do's and don'ts

send your physics teacher back to school! those swirls.warps and funny runs in old glass are exactly that! they used to melt sand and pour it on packed sand and then trowl it like concrete before it cooled. most were poured to size and were thicker on one end. might explain the thicker at the top or bottom of the 1200 year old churches
