When quartz sits at room temperature, it is known as alpha-quartz, or lower quartz. This is usually the label given to trigonal quartz. During a process called inversion, however, it is heated to 573 degrees Celsius (1063 degrees Fahrenheit) and transforms into hexagonal quartz, which is also called beta-quartz or upper quartz. At this point ...
