It does, actually.  As you increase the linear dimensions, the area 
(and, hence, the amount of glass you are getting) increases by the 
square of the linear increase, and price tends to track area (amount 
of glass).

To the extent that the price of regular float glass does not exhibit 
this sharp increase in price, it is because you are overpaying for 
small pieces or because the cost of cutting, which does not increase 
by the square of the linear increase, becomes a larger part of the total.

Best regards,
