Get burn time on vanilla items

[Bridging_Noob]

Hi.

I'm trying to make a custom mod that shows how long all kinds of fuel can burn in a furnace

and it works perfectly with custom items, but when I try and use vanilla items like coal

it only gives the value -1

Is there any other way to get the burn time on vanilla items?
