CREAMERY CONSTRUCTION 33 



1. Brick. Brick is perhaps the most satisfactory material 

 from which to construct a creamery wall, but it is also the most 

 expensive. The standard size of brick is 2 inches by 4 inches by 

 8 inches. The brick should be uniform in composition and 

 free from lime spots. A hard-burned brick is most durable; 

 but for a building located in the city, pressed brick is more 

 satisfactory for facing. A brick should be tested for its power 

 to absorb moisture. This may readily be done by the following 

 method : Place a brick in the furnace or in the oven of a kitchen 

 range; leave it there for 24 hours or until the weight of the brick 

 remains constant; then submerge in water for 24 hours; after- 

 ward, wipe it dry with a cloth and weigh. A brick absorbing 

 moisture to exceed 8 per cent of its own weight should be re- 

 jected. Such a brick will disintegrate during the winter season 

 when the moisture in it freezes. 



A one-story or two-story creamery building constructed from 

 brick should have a wall not less than 10 inches thick, allowing 

 2 inches for air space. The bricks should be laid with well- 

 filled, full-bedded joints 3/8 inches wide. The walls should be 

 plumb and straight, using a line on both sides of the wall through- 

 out its entire height. They should be securely bonded with 

 headers, and should be reenforced above all openings. All ex- 

 posed joints in walls should be neatly smoothed with the trowel. 



2. Hollow Tile. Hollow tile has been used quite extensively 

 during recent years in the construction of creameries. The 

 standard sizes of hollow tile are 4 inches by 8 inches by 1 2 inches 

 and 5 inches by 8 inches by 1 2 inches. The former is used more 

 frequently. What has been stated concerning the quality of 

 brick applies also to tile. It is tested in a similar manner, and 

 any tile absorbing moisture to exceed 5 per cent of its own 

 weight should be discarded. 



Hollow tile may be laid in two different ways either on 

 edge or down flat. If on edge and with a tile 4 inches thick, 

 the wall should be constructed 10 inches thick with a 2-inch 

 air space allowed. The principal objection to this wall, unless 

 cemented on both sides, is its unattractive appearance. If the 

 tiles are laid flat, a single layer will make a wall 8 inches thick.
