I’m planing some quarter-sawn oak with my stanley no.4 and cheap scrub plane and I’ve noticed both of my planes have an odd blue tarnish just behind the mouth of the plane! It definitely wasn’t there before I started this morning.
My first thought was that the metal had somehow been heated up and changed colour but I can’t imagine I was building up that much heat! I’ve been using a tea-light candle to lubricate the bottom of the soles – could this be tarnishing the plane? It would make sense because the portion of the sole just behind the mouth wouldn’t rub against the wood that much and therefore the wax could be on there for longer?
Here’s a picture. (The dark patch in front of the mouth is a reflection of my black camera)
Thanks for any insight,
