The hard sedimentary rock that often forms inside limestone is called chert. Chert is composed of microcrystalline quartz and can be found in nodules or layers within limestone deposits. It forms through the replacement of limestone by silica-rich solutions.
The siliceous limestone that is commonly found is known as chert or flint. It is a type of limestone that has a high silica content, giving it a distinctive appearance and often used for various purposes such as construction, decoration, and tool-making.
A hard sedimentary rock that forms inside limestone is called chert. It is composed of microcrystalline quartz and often forms nodules or layers within limestone due to the replacement of calcium carbonate by silica-rich fluids.
That composition is called a glass batch. It typically consists of raw materials such as sand (silica), soda ash, limestone, and other additives that are melted together at high temperatures to produce glass.
Silica is a mineral compound made up of silicon and oxygen atoms. It is commonly found in nature as quartz, and also in various forms like sand, glass, and clay. Silica is widely present in the Earth's crust and is found in rocks, soil, and sand.
