Manufacture of roofing compounds and ‘roofing 
papers”. 
For coating of wooden and steel pipes and masonry 
aqueducts”*. 
The U. S. Geological Survey gives the following uses 
of gilsonite?’: 
For preventing electrolytic action on iron plates of 
ship bottoms, coating barb wire fencing, coating sea walls 
of brick and masonry, covering paving brick, and proof 
lining for chemical tanks, roofing pitch, insulating electrical 
wires, smokestack paint, lubricants for heavy machinery, 
preserving iron pipes from corrosion and acids, coating 
poles, posts, and ties, toredo-proof pile coating, covering 
wood-block paving, a substitute for rubber in the manufact- 
ure of garden hose, and as a binder pitch for culm in mak- 
ing briquetes and eggette coal. 
OZOKERITE : 
Electrical insulator?* :—this is the most important use. 
A residual product obtained in purifying ozokerite which has 
a hard waxy nature is combined with India-rubber to give 
an insulating covering for ocean cables. Ozokerite has a 
resistance of 450,000,000 megohms per square centimeter 
as compared with 110,000,000 for paraffin. 
Manufacture of candles?°—Almost all altar candles are 
made from ozokerite. They will not drip or bend over and 
they have great illuminating power. 
As a substitute for beeswax:—Refined ozokerite has 
about the same properties as beeswax. It can be bleached 
perfectly white with chlorine, in which case it can not be 
distinguished from beeswax except by the taste*®. In this 
form it is used as an adulterant of, or a substitute for, 
beeswax. The manufacturers of ointments, pomades, 
salves, and plasters”? use some ozokerite. 
As a water proofing material it has considerable use. 
Paper waxed with it is employed in wrapping soaps, steels, 
and all kinds of articles requiring moisture-proof wrappings.
