When stained or art glass is used, the specifications generally limit

the cost, as the glass is made according to the architect’s designs

or to approved designs submitted by manufacturers. The price depends

more on the amount of lead or copper used than on the cost of the glass

itself, and therefore no very close estimate can be made. The following

figures are only approximate:

COST PER

SQUARE FOOT

Clear glass $1 to $3

Opalescent glass $1 to $3

Plate glass $2 to $4

Cathedral glass $3 to $5

Favrille glass About $8

Ordinary window, or sheet, glass is sold by the box, which contains, as

nearly as possible, 50 square feet, whatever the size of the glass may

be. There are two qualities of ordinary glass, known as _single_ and

_double thick_, the former being about ¹/₁₆ inch thick, and the latter

nearly ⅛ inch. Single-thick glass should never be used in panes over

24 in. × 24 in. in size. Table XV gives the number of panes of window

glass in one box of 50 square feet.
