Heat treating fake log?

I bought a fake wooden log from Pets At Home and i was wondering how to make it safe for my enclosure.

I have a fan oven, i’ve heard you should ‘bake it’ before hand, but the other people in my house aren’t comfortable with that since they think it would just set fire (and i’m not too sure either)

I don’t want to do anything dangerous because i’m a little scaredy cat lol

Please let me know if there’s any other ways, or let me know how to heat it safely

Thank you !
