uniformity of texture, as well as depth of color, which are generally 

 sought for. The mines owned by C. A. Borst at Clinton, Oneida 

 county, and those of the Furnaceville Iron Co., at Ontario, Wayne 

 county, supply most of the ore for paint. The hematite from the 

 former locality belongs to the oolitic variety and that sold to paint 

 manufacturers carries about 45 per cent iron. The ore in Wayne 

 county is of fossil character carrying about 40 per cent iron. The 

 red hematite from St Lawrence county is also used for metallic 

 paint. 



The manufacturers of metallic paint and mortar colors in New 

 York State include the Clinton Metallic Paint Co., of Clinton, the 

 William Connors Paint Manufacturing Co., of Troy, and the Rossie 

 Iron Ore Paint Co., of Ogdensburg. A large quantity of the 

 Clinton hematite is shipped to points outside of the State for manu- 

 facture. 



Both shale and slate are ground for paint, their color depending 

 largely upon the amount and nature of the iron oxids present. 

 When there is a large proportion of ferric oxid the shale and slate 

 may be sold as metallic paint. At Randolph, Cattaraugus county, 

 beds of green, brown and bluish shale occurring in the Chemung for- 

 mation have been worked for paint purposes. The red shale from 

 the base of the Salina formation has been similarly utilized in years 

 past, having been obtained from a locality in Herkimer county. At 

 Roxbury, Delaware county, a shale in the Catskill series was once 

 employed. The red slate of Washington county, which belongs to 

 the Cambric, is the principal source of pigments of this character at 

 present. The Algonquin Red Slate Co. of Worcester, Mass., and 

 A. J. Hurd's Sons of Eagle Bridge are producers of red slate 

 pigment. 



The ferruginous clay called ocher is of common occurrence, but is 

 not now worked in the State. Sienna, a deep brown variety of 

 ocher, is found near Whitehall. 



The production of mineral paints in 191 1 included 7 '237 short tons 

 of metallic paint and mortar color valued at $68,870 and 1646 short 

 tons of slate pigment valued at $12,864. The totals for 1910 were 

 8063 short tons of metallic paint and mortar color valued at $70,841 

 and 1400 short tons of slate pigment valued at $10,900. These 

 quantities represent only the pigments manufactured within the 

 State from local materials.
