Figure
1 Diagrams illustrating arch-brick calculations

Gives the sizes of refractory bricks for glass melting furnaces in shapes of squares, splits, tiles, blocks, straights, side arch bricks, end arch bricks, end arch bricks and crown bricks. The tolerances on the sizes are not given and may be the subject of agreement between manufacturer and purchaser. Includes arch brick formulae, numbers of bricks needed in combining sizes to form circles of given diameters and information to be supplied by a purchaser. Illustrates diagrams illustrating arch brick calculations.
