Feldspar, quartz, pyroxene, mica, magnetite among others.
it is not magnetic because, i have many of them.
Rhyolite is a rock type that is categorized by mineral composition. Scoria is a textural rock type. Like, Rhyolite can be smooth, or it can be scoria (sharper, bumpier, lots of vesicles).Think of it as a rock adjective.
In 1768/69 the Cornish Copper Company reclaimed land using crushed slag (scoria) and recycled its smelter waste to create cast building blocks for the docks it built at Hayle. It was also used extensively for the workers' cottages, shops, pubs and civic buildings.
Scoria is usually reddish in color but may be black.
no, extrusive because it is made by lava not magma.
Scoria typically contains minerals such as plagioclase, pyroxene, olivine, and magnetite. These minerals are commonly found in volcanic rocks and contribute to the characteristic appearance and composition of scoria.
Scoria is red due to the oxidation of iron-containing minerals.

Scoria igneous rocks primarily contain minerals such as basaltic glass, olivine, pyroxene, and plagioclase feldspar. Due to its formation from the rapid cooling of lava with volatile gases, scoria is characterized by its vesicular texture and low density. The composition can vary depending on the specific magma source, but these minerals are typically present in varying proportions.
Mafic, infact it is often refered to as: "the mafic version of pumice"
When Scoria rock comes in contact with vinegar, it may produce a fizzing or bubbling reaction. This is because the vinegar reacts with the calcium carbonate minerals present in the rock, releasing carbon dioxide gas.

No. Scoria is rock. It is inedible.
Not necessarily. Most scoria is basaltic, but some can be andesitic.
When scoria, a volcanic rock, is placed in vinegar (which contains acetic acid), it typically does not react significantly. Unlike limestone, which reacts vigorously with acids due to its calcium carbonate content, scoria is primarily composed of silicate minerals that are not affected by vinegar. As a result, there may be minimal bubbling or fizzing, but the overall reaction is negligible.
Scoria streak refers to the marks left by scoria, a type of volcanic rock that is typically dark-colored and has a porous texture due to trapped gas bubbles. When scoria is scraped across a hard surface, it can leave a streak that may vary in color depending on its mineral content. This streak can be useful for identifying the rock's properties and distinguishing it from other similar materials. In mineralogy, streak tests are often employed to determine the composition and characteristics of various minerals.
The streak of scoria rocks is typically a light-colored powder, often ranging from gray to reddish-brown, depending on the minerals present in the rock. Streak is determined by rubbing the rock against a porcelain plate, which reveals the color of its powdered form. This property can help in identifying scoria, which is a type of volcanic rock characterized by its vesicular texture and low density.
