When you drag a piece of calcite across an unglazed porcelain plat it leaves behing a white line?
The white line left behind when dragging calcite across unglazed porcelain is due to the abrasion of the softer calcite mineral against the harder porcelain surface. The powdery residue created is caused by the calcite being scratched off and deposited on the porcelain as a result of the friction between the two materials.
How an unglazed porcelain tile can be used to identify a minerel?
An unglazed porcelain tile can be used to identify a mineral through a process known as a streak test. By rubbing the mineral across the surface of the tile, it leaves a streak of powder. The color of the streak can help identify the mineral based on its unique characteristics.
What happens when you rub gold on unglazed porcelain?
When you rub gold on unglazed porcelain, it leaves a mark or streak that can reveal the purity of the gold. This is because pure gold (24 karats) will leave a distinct yellow streak, while lower karat gold may leave a lighter or different colored streak due to the presence of other metals. This method is often used in assays to test the quality of gold. Additionally, the unglazed porcelain provides a rough surface that helps in making the streak more visible.
