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.
The âscratchinessâ of wool all depends on its âmicronâ count â how fine the wool fibre is. The lower the number the finer the wool. Superfine Merino wool is the softest and should be between 16-18.5 micron. Anything about 19 micron some people will find that it will itch, depending on the personâs skin sensitivity.
