In general, no.
Even at 600 grit, the finish left behind by a silicon carbide belt is too rough to polish from. You generally need to move to a cork belt in order to pre-polish your glass and then to a felt belt or cerium impregnated belt for a final polish.
You can also fire polish from a cork surface. Fire polishing is also an option from the 600 grit belt, but it may or may not fit your final aesthetic.
