1 00:00:00,000 --> 00:00:18,000 We are going to talk about calcite. Calcite is a very common mineral found in most places of the earth. Calcite comes in over 300 different shapes. This is more than any other mineral. 2 00:00:18,000 --> 00:00:31,000 Pure calcite is colorless or white, but due to impurities it can be red, yellow, green, honey pink, black, brown or blue. 3 00:00:31,000 --> 00:00:50,000 An interesting way of identifying calcite is the acid test. When you place drops of a weak acid such as vinegar on calcite, it will bubble. 4 00:00:51,000 --> 00:00:55,000 We can use calcite for making medicines, buildings. 5 00:00:56,000 --> 00:00:59,000 We use concrete and asphalt. 6 00:00:59,000 --> 00:01:02,000 Thanks for your attention.
