12-Piece Introduction to Metamorphic Rocks Kit with 1 inch Specimens

This 12-piece Introduction to Metamorphic Rocks Kit includes 12 different metamorphic rock specimens: anthracite coal, biotite gneiss, coarse marble, fine marble, phyllite, white quartzite, pink quartzite, mica schist, red slate, green slate, gray slate, and soapstone. Each specimen measures approximately 1 inch and varies slightly in shape, size, and color. Metamorphic rocks form when other rock types are transformed through high heat and pressure. The kit allows students to test hardness, streak color, magnetic properties, appearance, and effervescence to identify specimens. Includes an identification card with images and a foam-padded storage box. Each specimen is hand-selected and processed by a geologist in Victor, NY. Suitable for geology classrooms and homeschool science.
