  • A SEM image of the edge of a leaf shows a calcium oxalate crystal. These crystals are found throughout the plant and are responsible for throat irritation when medical marijuana is smoked. Plants that have too many oxalate crystals are good candidates for modern THC extraction techniques. Calcium oxalate crystals in plants are called raphides. Humans have similar calcium crystals that can appear as kidney stones. These crystals help remove calcium build up in the tissues and make it undesirable for grazing animals to eat the plant. Magnification is x120 on the printed page.

  • The quartz crystal optical wedge is a simple technique to aid in specimen identification by inducing a color gradient in a polarizing microscope. The wedge is made from a crystalline block of quartz cut into a wedge angle so that the optical axis of the quartz is oriented either parallel or perpendicular to the edge of the birefringent crystal. A typical quartz wedge is useful for measurements of petrographic specimens (rock and mineral thin sections) or other birefringent materials. The quartz wedge compensator is also employed for the determining the direction of anisotropy (crystalline fast and slow axes orientation) in birefringent specimens.

  • Gypsum. Polarized light micrograph of a thin section of gypsum. Gypsum is a chemical sedimentary rock, composed mainly of hydrated calcium sulphate. It may grow as a crystal aggregate (as here) or in giant tabular crystals up to 1 meter in length. Gypsum is used in plaster of Paris, in Portland cement and as a flux in pottery. The most compact form of gypsum is known as alabaster. Sample collected in Penfield, New York.  Object size: 40 mm.

  • A Scanning electron microscope (SEM) image of a crystal structure found inside a micrometeorite. The field of view of this image is 80 um wide. Micrometeorites routinely fall all over the surface of earth. This is primarily an iron meteorite with small amounts of other elements. This meteorite melted from atmospheric melting as it was captured in the earths atmosphere. The frictional heating melted the martial and surface tension of the molten metals brought it to a circular shape. Magnetic iron micrometeorites are easy to find with the help of a strong magnet. The crystal structure of the meteorite is visible in this image.
