Just to clarify "flame polished" on acrylic was a metafor, meaning
the edge on acrylic that looks like flame polished on glass. Since
acrylic goes limp at about 225F and chars at about 450F (like paper),
unless someone has slid something by me, it can't be flame polished.
It is normally polished with buffing wheels a lot like glass but a lot
faster.

No, it's a literal description of running over the cut edge of a piece
of acrylic with a propane torch. It takes some finesse, but does work,
though not in this case where a very flat surface is required.
