how does smelting detect who is smelting? 

is it the person who last placed stuff in it? is it the person who placed the furnace? does it matter who put the fuel in?

It's the person who puts in the ingredient that causes the furnace to start smelting. It then works out the time the fuel should burn from based on that player's level at that point in time.124.182.112.128 07:12, April 4, 2014 (UTC)

Reason it is a child skill and hence gives no mcmmo skill xp to any skills[]

Bukkit can detect what a player puts in a furnace and what it takes out, however it cannot tell whether that was the same item or the same player. For this reason, there is no way to ensure that a player is smelting the items him/herself and whether all that was put in was smelted or not. This is why smelting is a child skill and does not give any mcmmo smelting xp or to any other skill such as parents.124.182.112.128 07:09, April 4, 2014 (UTC)
