When glass breaks, why don the pieces fit perfectly back together?
“When glass and china break stress is released. The broken sections spring out of shape. Sometimes when items are put back together the mend line may not be even. It may have a slight high/low. We try to align the sections as best we can, but in some cases it is not possible.” Source and further information: http://www.montanosglassrepair.com/framesetFAQ.
