PENNSYLVANIA CRUDE OIL, SP-42 Appalachian Basin, Pennsylvania and Michigan Basin, Michigan.  Two crude oils consisting of saturated paraffin hydrocarbon compounds available - light (sweet) and heavy (sour).  Pennsylvania Crude is mostly a light sweet crude that does not have the high levels of sulfur that other crude oils have.  Some available in 4 mL, 40 mL, 100 mL and 250 mL bottles.  The "sour" heavy crude is also available from the Michigan Basin.  We will be updating the petroleum section soon.  Not all sizes available for every type.  Inquire for locations.

TEKTITE (Lei gong mo) SP-57 - Impact Crater Melted Rock.  Guangdong, China.  Tektites are pieces of glass formed when a large meteorite strikes the Earth.  They look similar to 

obsidian glass but chemically can be differentiated from obsidian.  Tektites are closer to shale 

in composition. These "splash-form" tektites have rounded, aerodynamic shapes such as spheres, tear-drops, dumbbells, and disks.  

THENARDITE, SP - 61. California.

Dark gray to black sharp crystals and groups of this

classic evaporate mineral.  Beautiful crystals for the species
