There is no other book quite like this in publication at present, and it is prompted now because much general scientific knowledge can be, and is, applied to the manufacture of structur

History and Classification,raq. It is clear that the art of brickmaking had already advanced into the process of firing to make them hard, durable, and esthetically attractive. Simple molds were probably used by these people to make the bricks true in shape and size.

Plant Layout and Design,ction units of 100,000 standard brick-equivalents per day, and pipe plants should have a minimum output of 120 tons of ware per day. Probably the economic break-even point for face-brick production is about 60,000 units per day.

Future Trends, as any to start. At least if past trends are to change, we know that some basic patterns must change; and if such changes are a part of the predictive process, they must be justified. If the driving forces of the past remain unchallenged, then the trends of the past can be a satisfactory guide to the future.

Mineralogical Composition of Structural Clay Products,ures of these minerals, as well as the clays, is important in following the progress of the high-temperature reactions. The structural clay products engineer and scientist cannot solve the technical problems that arise without a good foundation in the crystal structures of the disilicate minerals.

History and Classification,y about 4500 years ago, and the people were, no doubt, located in Mesopotamia along the Euphrates River or its tributaries. This area is now part of Iraq. It is clear that the art of brickmaking had already advanced into the process of firing to make them hard, durable, and esthetically attractive.
