Lava Pickaxe or Smelting Enchantment

A pickaxe that you can craft from blaze rods as sticks and possibly a diamond and magma blocks. The lava pickaxe would be a tool that could not burn in lava as well as being able to smelt ores when you mine them. It would be an item that would mine about as fast as diamond and could even be crafted in the smithing table. If a new pickaxe seems like to much, a new enchantment called burning touch, or something along the lines could be enchanted onto existing pickaxes to give them the same special effects as the lava pickaxe. Thank you for reading my suggestion.
