Hi Folks,
 Amongst my large collection of paperweights i have 2 Vasart/Ysart Bros weights with ground bases, both weights have a crescent shape left behind after grinding, (sorry i can't add pics as i no longer have my own pc) embedded in the crescents is a red dust, i assumed this was polishing compound. is this a possibility?

Not sure with your weights but in mine the red ring is still 2-3mm embedded in the base clear glass, so I think the red glass being on the end of the pontil rod is the most likely.

Early in the century final polishing was done with rouge rather than cerium as it is now.  You red powder may well be from the polishing process.

But it wouldn't polish into the glass; you are removing a thin layer of glass with the cerium. The powder might stay in a "crack" but then you could remove it by poking or washing it out.
