DESCRIPTION
Halite is rock salt, that is sodium chloride, as found in mineral deposits. It was used in experiments involving radiant heat since infrared rays propagate better in halite than in glass. Exhibit 264 consists of two halite prisms contained in two glass cylinders, held steady in bases of cork. The triangular bases of the prisms are inscribed exactly in the bases of the respective cylinders which are sealed with wax.BIBLIOGRAPHY
