Kaline Bats/flame burned

[earlywynnfan]

OK, I should know this by now, but how do you differentiate between a Flame burned bat, like Kaline used, and a regular finish? And what's a wax finish?

While I'm on Kaline, are there any specific hallmarks for his bats that I need to look out for, like the Snider or Mize tape jobs?

Thanks,
Ken
