Explain why color was not a good identifier with the Quartz Necklace.
3 answers
The color was not a good identifier with the Quartz Necklace because quartz can be found in a wide range of colors, including clear, white, pink, purple, yellow, brown, and even black. Therefore, relying solely on the color of the necklace would not have been a reliable way to identify it. Additionally, quartz can also be dyed or heat-treated to achieve different colors, meaning that the color of the necklace could have been artificially altered.
Explain how glass is used to help ID minerals.
Glass is commonly used as a tool to help identify minerals due to its distinctive properties. When a mineral is scratched against glass, it leaves behind a specific streak, which is the powder or residue left on the glass surface. This streak can provide valuable information about the mineral's hardness and composition.
Additionally, glass can also be used as a tool for determining a mineral's cleavage. Cleavage refers to the way a mineral breaks along planes of weakness. By comparing the way a mineral breaks with the way glass breaks, geologists can determine the cleavage of a mineral.
Furthermore, glass can be transparent, translucent, or opaque, which can help differentiate between minerals with different levels of transparency. This property becomes especially relevant when identifying minerals such as quartz, which can have a glass-like appearance.
Overall, glass serves as a useful tool in mineral identification by allowing for the assessment of streak, cleavage, and transparency, all of which are crucial characteristics to consider during the identification process.
