I would strongly encourage anyone to avoid doing this. Yes, I see for some people it seems to work, but then, some people have parachutes malfunction and live.
If you have bottle with 2 volumes of CO2 carbonation (reasonable beer levels) and you heat the bottle to 190F, the pressure in the bottle will be 98 PSI. Beer bottles aren't really designed for that level of pressure (I think they may test them at 60 PSI but don't quote me). If you have 3 volumes of CO2 you'll be at 135 PSI. Glass is extremely unpredictable when it comes to shattering and faults and if you reach in to grab 190 F bottle with 100-135 PSI in you are just begging for grief.
I have no problem with pasteurization, but heating carbonated liquid in glass bottles is not a safe practice at home.
