Removing broken glass from modern pachinko frame

[Blastronaut]

The glass repair company is currently trying to remove the broken glass from my 2008 Back to the Future pachinko frame (Sammy), but they are having real trouble removing the broken glass. Whatever is being used to hold the glass in place seems to be very difficult to remove. Does anyone know what that compound is and how to remove it without applying heat which could melt the plastic frame around it?

Not sure. Its certainly tougher than generic window sealant
