Best heating method to remove screen

The screen of my Motorola One Action is broken. I read that a heat plate is the best option to meld the glue and disassemble the back part of the phone, but I don’t own one, and it’s way too expensive for a one time repair. A hair dryer seems to be an option, that can somehow be risky (overheat possible). I was asking myself if putting the phone in a kitchen oven at a temperature of 70 °C for 10-15 min could be a viable option ?
