THE POTTERY INDUSTRY. 293 



THE DEPARTMENT OE CEAY WORKING AND CERAMICS AT THE 

 STATE COEEEGE, NEW BRUNSWICK, N. J. 



This school of clay working - and ceramics was established by 

 Legislative enactment in 1902 for the benefit of the clay-working 

 industry of New Jersey, and it is maintained by an annual ap- 

 propriation. Similar schools are numerous in Germany, and their 

 usefulness has repeatedly been demonstrated. In the work of 

 the department provision has been made for a careful study of the 

 clays of the State and the methods of manufacture employed. 



The equipment is housed in a commodious laboratory especially 

 adapted and arranged for the purpose. This building is located 

 on College property adjacent to the campus. The front of the 

 main portion is of the Colonial style, plainly but well executed in 

 buff brick. 



The workshop contains nearly 1,700 square feet of floor space, 

 which provides an admirable place for the machinery installed. 

 Here is located the 30 horsepower electric motor. The power is 

 distributed by two lines of shafting furnished with split steel 

 pulleys. The brickmaking outfit (PI. XXXVI) consists of an 

 auger brick machine of a capacity of 20,000 brick a day, a hori- 

 zontal pug mill and a down-cut board delivery table. Appliances 

 for the potter and the tile maker also ; find place in this shop. The 

 machinery for that purpose consists in part of the following arti- 

 cles : A dry pan or grog mill arranged for wet and dry grinding, 

 a clay-mixing and preparing machine or a combined blunger, agi- 

 tator, lawn screen, filter press and slip pump with a capacity of 

 500 to 1,000 pounds a day, a four-jar glaze mill, a large size 

 ball mill, a combination pull-down and jigger combined, a pot- 

 ter's pug mill, a wad machine, a hand jigger, sieving machinery, 

 a tile press and other necessary appliances, all of the latest design 

 and representative of the chief types used in the manufacture of 

 a wide range of wares. 



In an adjacent room is a wet closet built of porous brick with 

 a terra-cotta lumber ceiling. The outside is covered with a coat 

 of cement. In this room; may be stored unfinished clay wares 

 which may be kept damp for a long period.
