Established in 1984, Oglesby and Butler has established themselves as the world leader in manufacturing butane powered smoldering irons, glue guns, and heat tool kits. In 2009, they ventured into the portable vaporizer market with the introduction of the highly anticipated Iolite Vaporizer. Utilizing a bi-metal thermostat, the Iolite Vaporizer is constantly regulated to maintain a temperature that does not exceed 400°F. Compact and lightweight, the Iolite Vaporizer is the definition of portability. It requires absolutely no batteries, flame, cords or wires of any kind.
