With electrical vaporisers the herb chamber is heated electronically, not with a flame. There are two methods. Conduction, vaporising through the direct application of heat to the herb chamber and convection, vaporising by the application of heated air (the nicer way).
Electrical vaporisers from Blackleaf.de are available in all shapes and sizes. Pen, pocket, handheld, and table vaporisers.

When the vaporiser is set-up correctly, the herb should not show any brown colouring. Black colouring shows that the material was heated to a too high a temperature. In Academy Article Vaporiser 2 will be explained exactly which active ingredients will be released at exactly which temperature.
