Cerium oxide, combined with some water and heat, chemically bonds to the glass to fill the ultrafine scratches left behind by the previous abrasive (typically pumice). That heat – which is a result of friction – may be what you are remembering. That little bit of warmth (just warm to the touch – too much and you can thermal shock the glass) is a far cry from fire polish temps.
