When you have made a Disc, Iron Disc, or Alumim Ingot, right-click the Anvil while holding the item in your hand to place it on the anvil. Then, by HOLDING the left-click while using a hammer, hit the disc. (Note, they tend to take very long.) If you place Pokéballs under you will create faster. Also if you use a diamond hammer it will last twice as long as other hammers.Each item that you put onto the Anvil has three stages of completion. They are visually represented by discs getting rounder and Aluminum Ingots getting flatter. Once they have been affected three times you right-click on the anvil and the finished product will pop off.
