Thanks to JHolland's extra information, I have turned up more about the production, including the tricky annealing process. This comes as no surprise since the two rock types are very closely related, but they are two distinct rock types that should be treated as such. It is also sometimes found near the upper crust of basaltic lava flows. The word scoria comes from the Greek , skria, rust. With the proper type of shale, the material will have the properties, appearance, and vesicles of scoria. While all scorias are highly vesicular, it is also possible (and even common) to describe their texture in other ways. Scoria can be obtained by smelting Soul Sand in a Furnace or by Bulk Blasting. Xystozukalia Theiss. Only particular shale types will produce results similar to scoria. Rhyolitic magmas contain more gas than basaltic magmas. It is also very popular for use in concrete for its light weight and insulating properties. Some pumice is so full of vesicles that the density of the rock drops low enough that it will float. 4 What kind of minerals are found in scoria?
