THE MIXING AND QUARRY INDUSTRY I907 5/ 



The glass sand produced in New York comes from the vicinity 

 of Oneida lake. The principal localities where it is found are 

 , in the towns of Rome, Verona and Vienna, Oneida co., and 

 Constantia, Oswego co. At one time this section supported a 

 large industry in the manufacture of window glass, with factories 

 at Durhamville, Constantia and Cleveland, but the cost of fuel 

 became a serious handicap when competition was encountered 

 with centers of manufacture in the natural gas and soft coal 

 regions. Small quantities of the sand are noAV shipped to other 

 parts of the State for making bottles and common w^ares. The 

 shipments in 1907 amounted to 1200 short tons valued at $1380. 



Some of the sandstones of New York have been used in the 

 past for glass making. The Shawangunk grit was once quarried 

 near EUenville, Ulster co., and the output sold to Pennsylvania 

 companies. The Potsdam sandstone has likewise been used for 

 the purpose. 



Molding sand. This material is produced largely along the 

 Hudson river valley, in Albany, Columbia and Dutchess counties. 

 The deposits are a part of the water-washed glacial accumula- 

 tions of the region and are found in the upper section imme- 

 diately underlying the soil. The valuable portion ranges from 

 a few inches up to several feet thick. The sand contains a little 

 clayey matter which contributes to its firmness and plasticity. 

 The finest grades are used for stove and other castings that 

 require a smooth finish and are shipped to Albany, Troy and 

 more distant points. Sand used for making cores in molding 

 is obtained from Oneida lake, from the same deposits that yield 

 glass sand. 



SAND-LIME BRICK 



There have been few changes in this industry during the year. 

 The activity shown in the erection of new plants for the manu- 

 facture of sand-lime brick was less noticeable than in the pre- 

 ceding year, no doubt due in part to the smaller demand that 

 has been experienced for building materials of all kinds. Reports 

 were received from 12 plants, of which nine were operative 

 during the whole or part of the year, and the production 

 amounted to 16.610,000 valued at $109,677. The seven plants 

 that reported as active in 1906 made an output of 17,080.000 

 valued at $122,340. The plant of the Rochester Composite IVick 

 Co. was destroyed by fire but is to be replaced. The following 

 is a list of tlie companies engaged in tjic industry in the State.
