| Moh's hardness scale | A scale used to measure the relative hardness of a mineral by its resistance to scratching. |
| fracture | the cracking or breaking of a hard object or material |
| streak | a long, thin line or mark of a different substance or color from its surroundings. |
| clevage | a sharp division; a split. |
| hardness | the quality or condition of being hard. |
| crystalization | Image result for crystallizationen.wikipedia.org Crystallization is also a chemical solid–liquid separation technique, in which mass transfer of a solute from the liquid solution to a pure solid crystalline phase occurs |
| solution | In chemistry, a solution is a homogeneous mixture composed of two or more substances. In such a mixture, a solute is a substance dissolved in another substance, known as a solvent. |
