ii INTRODUCTION Perlite is not a trade name, but generic name for naturally occurring siliceous volcanic rock. The distinguishing feature which sets perlite apart from other volcanic glasses is that when heated to a suitable point in its softening range, the product expands four to twenty times its original volume. Perlite expansion is due to the presence of two to six percent combined water in the crude perlite rock. When the crude ore is quickly heated above 870 0 C (1600 0 F), the product pops in a similar manner to popcorn. The combined water vaporizes in the ore creating lightweight particles with countless internal cells and high surface area. These tiny glass sealed bubbles have many physical properties of perlite include the product’s lightweight feature, absorption ability and insulation values. The wide specification of perlite make the product adaptable to numerous applications in the construction, industrial, chemical, horticultural and petrochemical industries.

1 1.0 HISTORY The Perlite Institute was founded in 1949, a year in which it is estimated only 80,000 tons of perlite ore was mined throughout the world. The unusual properties and advantages of this virtually new material had been known for some time, yet recognition and acceptance was impeded due to a lack of reliable technical data, uniform commercial standards and sufficient public information. What was needed was a coordinated effort, a continuing campaign to secure the future
