GT-N5100 lcd/screen separation

Iam looking for the best way to separate the lcd from the glass and digitizer. My problem is, that the lcd is broken but the glass is intact. I want to reuse the glass and digitizer but with a new lcd.

I do not have a professional hotplate separator machine and wont get one in the near future so please leave that option out!

Many videos work with prying tools and cards but I fear that will break the glass. I was thinking of using wire and hot air?
