Armor that is currently worn by the player cannot be detected by the recipe book. This includes gold, iron, and chainmail armor (all of which can be smelted into their respective material nuggets).

Steps to Reproduce:

1. Equip either gold, iron, or chainmail armor
2. Give the player all recipes:

   /recipe give @p *
   

3. Open the recipe book inside a furnace, or blast furnace
4. Turn to the 'ores' tab

Observed & Expected Results:

- All recipes will be impossible to complete, despite having the required items to complete them.
- As the player currently has one of the applicable items inside their inventory, it would be expected that the recipe would be possible to auto-complete.
