Science Education Supplies By Eisco

• CHALCOPYRITE | From the same family as fool's gold, Chalcopyrite is a yellow crystalline mineral consisting of a sulfide of copper and iron. It is the principal ore of copper formed in hydrothermal veins
• GREAT FOR GEOLOGY CLASSROOMS | Chalcopyrite's formation exhibits fracture and has a brassy luster which make it an excellent tool for studying economic geology, and is great for us in comparative identification exercises
• GEOLOGIST SELECTED | Each specimen is selected and hand processed by an actual geologist, ensuring each sample exhibits defining features
• LOCALLY PROCESSED | Our rock and mineral samples are sourced from a variety of locations around the world and are processed in Victor, NY
• INDIVIDUALLY PACKAGED & LABELED | Each specimen sample is packaged in a transparent bag, and is labeled & barcoded for easy identification

• Half circle is made of acrylic with an indicator line half way across the arc
• Dimensions are 3 inches long, 1.5 inches wide, 0.75 inches tall
• Typical uses for a device such as this are reflection, refraction, wave demonstrations, Snell's law, observational study

• BRECCIA | The large, angular clasts in breccia make it possible to confidently ascertain the depositional history of the rock
• GREAT FOR GEOLOGY CLASSROOMS | Ideal for identification & classification exercises. This contrasts well with conglomerate, a very similar rock with clasts that have traveled a long ways from their provenance
• GEOLOGIST SELECTED | Each specimen is selected and hand processed by an actual geologist, ensuring each sample exhibits defining features
• LOCALLY PROCESSED | Our rock and mineral samples are sourced from a variety of locations around the world and are processed in Victor, NY
• INDIVIDUALLY PACKAGED & LABELED | Each specimen sample is packaged in a transparent bag, and is labeled & barcoded for easy identification

• This rectangular plano glass mirror - pack of 10 is designed for physics and educational uses.
• It is approximately 3\" x 1\" and 2mm thick. Note, thickness varies as they are not designed to be consistent in that respect.
• Because of their educational use design, there may be minor imperfections that do not affect physical function.
