Description: | Gypsum is a very soft mineral. So soft, that it can be scratched with a finger nail. This is a useful test for distinguishing gypsum from other minerals, most of which are harder. This specimen is typical of gypsum from the Kirkby Thore area, and is known as'daisy bed' gypsum, because the star shapes formed by the crystals look a bit like daisy flowers. Gypsum is a common mineral, and is found in many countries. | License: | http://www.imagine.org.uk/about/copyright/ | Rights holder: | Tyne & Wear Museums | Subjects: | rocks and minerals natural world | Source: | Tyne and Wear Imagine | Identifier: | http://www.imagine.org.uk/details/index.... | Go to resource |
