while it is in the drier and is used for small steel cores, glazing 

 tile, and plaster. The product of this plant is used principally 

 for steel castings and furnace bottoms. Minor uses are on 

 traction lines, in brick making, and to a smaller extent in the 

 manufacture of glass. Pittsburgh is the principal market. 



The plant produces 200 tons of sand per day on the average. 

 It is said to have been in operation about 30 years as a sand 

 plant and prior to that time the quarry was worked for dimension 

 stone. 



The composition of the sand from this and adjacent plants 

 in Sugar Creek Valley is shown by the following analyses: 



Silica, Si02 



Alumina, AI2O3 



Ferric oxide 



Calcium oxide, CaO. . . . 

 Magnesium oxide, MgO 

 Titanium oxide, Ti02. . ,

Microscopical examination of a run-of-quarry sample of 

 sand from the plant of the Massillon Stone Company at Barrs 

 Mills showed the presence of the following minerals which are 

 listed in order of their abundance: 



1. Quartz. 



2. Microcline. 



3. Feldspars. 



4. Limonite. 



5. Kaolinite. 



6. Tourmaline. 



7. Chlorite. 



8. Zircon. 



9. Titanite. 

 10. Serpentine. 



Dundee, which is situated about 3 miles north of Barrs Mills, 

 has long been an important sand producer. Here are located 

 the plant of the National Malleable Castings Company and 

 that of the American Sand Company. Both work the Dundee 

 sandstone, the rock being broken in gyratory crushers and 

 then passed through rolls and over screens. Steel castings and 

 furnace bottoms are the principal uses of the product.
