Teachers MINERAL HARDNESS TEST KIT - Mohs mineral hardness scale 1-9 (talc, selenite, calcite, fluorite, apatite, feldspar, quartz, topaz, corundum) in a resealable bag with a key identifying the hardness of each mineral. The teachers version - large pieces and identified by affixed number. Teachers includes streak plate, glass plate and nail, and instructional booklet. Extra charge for diamond crystal.

We are now offering a new student hardness test set based on teacher requests. It you want larger pieces but still in an affordable price range, this new sized hardness test set is for you. Because you asked for it! MHK-SL - $10. (Add $1.50 per set if you would like samples numbered) Not included are streak plate, glass plate and nail.
PROPERTIES OF MINERALS - ES-500 - 18 compartment boxed set that explores not only Mohs 1-9 but other Properties of Minerals. Minerals included are the 9 Mohs scale minerals mentioned above plus galena (heft, s.g.), magnetite (magnetism), "optical calcite" (birefringence), muscovite mica (cleavage), sulfur (color, smell), massive barite, crystalline barite, pyrite crystal, halite (salt). Booklet with information on each item and photo ID. Streak plates, glass plate, magnet. $40 (plus s&h) This has become our one of our top-selling boxed kits in the signature blue-linen box.
Earth Science Kit ES 200 and ES250 are both designed for the teacher in mind. Each kit contains 18 specimens in a compartmented box with photo identification, instructional booklet with detailed specimen and geology descriptions and explanations. How do the two kits differ? Basically, ES200 is your "traditional" mineral and rock kit that contains samples of common rock-forming minerals and the rocks that they form. ES250 is a little "less traditional". It also contains samples that talk about basic geology. But it also uses other minerals to talk about economic uses of minerals, or interesting properties and processes. For example, galena demonstrates luster and cleavage; malachite demonstrates streak; magnetite represents magnetism; the rock cycle of quartz to sandstone to quartzite, etc. Prices below.
Earth Science Kit ES-200. MINERALS ROCK! Common minerals and the rocks they form. 18 specimens. 6 minerals: quartz, calcite, muscovite mica, hornblende, microcline feldspar, biotite mica. 4 sedimentary: conglomerate, fossil limestone, sandstone, shale. 4 igneous: granite, diorite (intrusive); obsidian, pumice (extrusive or volcanic). 4 metamorphic: quartzite, slate, mica schist, gneiss. $35 (plus s&h)
