Helenite is made by heating rock dust and particles from the Mount St. Helens area in a furnace to a temperature of approximately 2,700 °F (1,480 °C). Although helenite and obsidian are both forms of glass , helenite differs from obsidian in that it is man-made.
Alternative natural materials, specifically their applications, have only recently made their way into more common use. The modern problems of global warming and climate change shifted more of a focus onto the materials and methods used to build our cityscape and homes. As environmentally conscious decisions became commonplace, the use of ...
A natural material is any product or physical matter that comes from plants, animals, or the ground which is not man-made.

For most man-made materials there is a high degree of control in the processing methods of the final product leading to normalized properties. In the case of these mycelium based materials there is less control, because of these materials properties vary significantly and depend not only on the processing of the material but also the growth ...
