For further shapes please take a look at the Brown #700 range on this page: EVEFLEX TECHNIK Mounted Rubber Polishing Burrs
Using these Brown Rubber bullet polishers in glass engraving will provide the perfect subtle shading tool. Use after the Mini Rubber Silicone Bullet polishers in black (MSPBB). The brown will give a slightly more subtle shading effect than the black. Alternatively, use after the grey rubber silicone polishers (GRSPB)
They will also help to smooth out White Arkansas stone burr (ASB1), or Green Silicon Carbide Stone Burr (SCB) marks leaving a texture of its own.
Helpful Tip: Sometimes you will find that you want to polish the top of an area without going into the cut you made with diamond burrs so that the top is dark but the cut is still white.
This is done by using a hard polisher such as the brown rubber polishers to smooth out the top surface ("mountains") without going down into the cuts ("valleys").
If you want to do the reverse and just polish the valleys without touching the mountain tops then you can use a Mini Rubber Silicone polisher (MSPM) in knife edge or wheel shape to follow the path of the "valleys" without touching the surrounding "mountain tops".
