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.
However, as is clearly illustrated in the photograph, the steel wool conducts electricity. The texture of steel wool is quite peculiar. Depending on the type of steel wool one observes and handles, its texture will be different.
