Strombolian - These eruptions are characterized by distinct blasts of basaltic to andesitic magma from the vent. 1  These blasts produce incandescent bombs that fall near the vent, eventually building a small cone of tephra (cinder cone). Sometimes lava flows erupt from vents low on the flanks of the small cones.
Use steel wool for a satin finish. The scratch pattern left by a gray abrasive pad on the top is more aggressive and uneven than that left by 0000 steel wool. you get a better surface by rubbing out the final coat with steel wool than with an abrasive pad.
Sustainability âMineral wool and glass wool are made of recycled materials such as slag, glass, and other industrial byproducts. It is one of the most energy-efficient building materials: the energy saved from its use as a thermal insulator quickly eclipses the cost of its sourcing and manufacture.
