Question
Clay with a high concentration of this mineral is more susceptible to dunting when firing a kiln because it changes from its alpha to its beta form at 573 degrees Celsius. To save cost, PZT is sometimes used to replace this mineral in a system developed by George W. Pierce. This mineral is the most resistant to weathering on the (*) Goldich dissolution series. Because of its low crystallization temperature, this mineral appears at the bottom of Bowen’s reaction series. Microcrystalline forms of this mineral make up different types of chert, like agate and onyx. This mineral’s piezoelectric properties enable its use in digital watches. For 10 points, a value of seven on the Mohs hardness scale corresponds to what mineral made up of silica? ■END■
