The deposit is approximately 300 feet deep and is located on a 16 acre site. Our warehouse and production facility includes a 3000 square foot bulk handling area for use in processing our Sheffield Clay. Special properties of this clay are its plasticity, fired color and unique particle size. The raw clay is a pure clay, with no stones, sticks or other contaminants. Our tested formulas blend Sheffield Clay with other more common clays, resulting in a distinct, high quality range of construction clay bodies unequaled in the Northeast.\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-weight: bold; text-decoration: underline;\"\u003eLow Resistance Earth Grounding:\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eOur natural earth has been tested for conductivity and is shown to be suitable for use in low resistance soil for buried electrical grounding cable. The conductivity tested at 4200 Ohm Centimeters and can be furthur enhanced by adding 1 100lb bag of calcium chloride per 10 cubic yards of the Sheffield clay. Spread the calcium chloride about 4\" below the surface and soak thoughly to permit the chloride to disolve into the soil. Deep and shallow earth grounding systems are critical for protection of personnel and sensitive electrical equipment. A suitable electrical grounding system improves resistance to uneven power and limits the amount of noise in commercial electrical systems.
