Rock and Mineral Specimens and Collections
Eisco™ Microcline Feldspar Mineral Specimen
Microcline Feldspar Mineral Specimen for use in study of physical properties like hardness, cleavage, and crystallization temperature.
Eisco™ Sulfur Mineral Specimen
Sulfur Mineral Specimen ideal for mineral identification exercises, due to its instantly recognizable physical properties.
Eisco™ Muscovite Mica Mineral Specimen
Muscovite Mica Mineral Specimen forms in thin sheets that are individually weak, but comprehensively strong.
Eisco™ Porphyritic Granite Specimen
Porphyritic Granite Specimen is a must-have sample when discussing rock types, rock cycle, formation, classification, and identification of igneous rocks.
Eisco™ Siltstone Specimen
Siltstone Specimen is a clastic rock made up of small, nearly microscopic grains of silt.
Eisco™ Labradorite Sedimentary Rock Specimen
Labradorite is a variety of plagioclase feldspar, intermediate between anorthite and albite. Notable about this species of feldspar is its potential for iridescence.
Eisco™ Pyrite Mineral Specimen
Pyrite Mineral Specimen has a shiny metallic luster and bright brassy color, making it an ideal addition to mineral collections or classroom exercises.
Eisco™ Black Hematite Mineral Specimen
Hematite specimen that is ideal for demonstrations in mineral physical properties.
Eisco™ Red Sandstone Specimen
Red Sandstone Specimen is made up of well-sorted and well-rounded grains of quartz.
Eisco™ White Quartzite Metamorphic Rock Specimen
Quartzite is formed from sandstone that has been tightly compressed to the point where the clasts have recrystallized to form a new rock. This formation mechanism, coupled the inherent strength of quartz, makes quartzite a very durable rock.
Eisco™ Oligoclase Mineral Specimen
Oligoclase is a feldspar with high levels of sodium.
Eisco™ Corundum Mineral Specimen
For study of mineral hardness and crystal habit - EISCO Corundum Mineral Specimen is used in classroom identification labs and exercises, correlates well to Next Generation Science Standards Evidence Statements.
Eisco™ Limestone Specimen
Limestone Specimen is made up of mostly calcium carbonate and organic material.
Eisco™ Biotite Gneiss Specimen
Biotite Gneiss is high-grade metamorphic rock formed from other rocks undergoing alteration from intense heat and pressure.
Eisco™ Raw Chlorite, Metamorphic Mineral Specimen - Approx. 3 Inch
Chlorite is a metamorphic mineral that has undergone light alteration. During metasomatism, phyllosilicate minerals may become hydrated and form chlorite.
