Basaltic lava is a type of lava that is low in silica content and high in iron and magnesium. It is known for its low viscosity, which allows it to flow easily and cover large areas. Basaltic lava typically erupts from shield volcanoes and is responsible for creating expansive lava plateaus and basaltic rock formations. It is one of the most common types of lava on Earth and can be found in regions such as Hawaii and Iceland. **

Basaltic rock wool does have some shielding properties against electromagnetic radiation, particularly in the lower frequency range. However, its effectiveness in shielding higher frequency radiation, such as that from Wi-Fi or cell phones, may be limited. It is important to note that the thickness and density of the rock wool, as well as the specific frequency of the electromagnetic radiation, will all impact its shielding capabilities. Therefore, while basaltic rock wool may provide some level of protection, it may not be sufficient for all types of electromagnetic radiation. **
