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.
I used to use all of the pads but find that the purple wool pad used with polishes does the trick at every polishing stage. It is easier and faster to use the purple wool pad saving time and money. I usually follow with a white pad and SF 4000 or SF 4500 to finish the surface with.he Lake Country Purple Foamed Wool Pad is a break through product that gives you outstanding cutting power with greatly improved ease of use. This pad will give you more cutting power than a yellow foam cutting pad, without the harmful downsides of traditional wool pads.
