The composition is a 40-60% aqueous slurry of pigment containing ferrosoferric oxide and a silicate/clay mixture which is suitable for coating the surface of the mineral granules. The invention also pertains to a process for the manufacture of the coated granules, to the dry coated mineral granule product containing ferrosoferric oxide bonded in a silicate/clay matrix which is suitable for surfacing asphaltic shingles, to the dried composition containing from about 5 to about 50 wt. % total pigment in a silicate/clay matrix in which the pigment contains Fe3O4 in a concentration of between about 2 and about 100% and to a Fe3O4 pigment mixture per se.Type: GrantFiled: June 4, 1999Date of Patent: May 22, 2001Assignee: ISP Investments Inc.Inventor: Ingo B. Joedicke

Patent number: 6190754Abstract: The variegated shingle comprises a shingle layer having front and rear surfaces the front surface including a butt portion and a headlap portion. The shingle layer contains granules on the front surface forming a plurality of horizontal striations providing gradations having color values ranging from light to dark extending between a leading edge of the butt portion and an upper portion thereof. The striations include an upper striation along the upper portion, a lower striation closer to the leading edge, and an intermediate striation between the upper and lower striations. The upper striation is darker in color value than the lower striation, whereas the intermediate striation is no darker in color value than the upper striation and no lighter in color value than the lower striation. The color values of at least one of the upper, lower, and intermediate striations vary across the granule layer.Type: GrantFiled: December 24, 1997Date of Patent: February 20, 2001Assignee: Building Materials Corporation of AmericaInventors: Alfredo A. Bondoc, Frederick W. Sieling, William R. Carroll

Patent number: 6156289Abstract: Method of preparing colored roofing granules (18) from granulated mineral-containing matter having an elemental iron content of about 15% to about 70% is disclosed. The method comprises heating the granules (18) to a temperature of from about 450.degree. C. to about 1,000.degree. C. and maintaining the temperature for a period of time sufficient to effect a color change in the granules. The resulting oxidized granules are permanently colored and will not fade in use.Type: GrantFiled: November 10, 1993Date of Patent: December 5, 2000Assignee: Minerals Research & Recovery, Inc.Inventors: Manjit S. Chopra, Michael D. Vick
