I have no idea what the schedule is in Celsius... I'll try to sort that out for you...
For soft glass punties, it's similar to boro, but you don't need the tip of the piece you're attaching to be super hot... just soft and tacky... the heart or other off mandrel piece should be warm, but hard... the best way to practice is with two rods... not a piece you're working on... once you get it sorted out, then you can start using the tech to make pendants with out ruining them.
