As I recall this is a spell you click on to learn, like a book.
Once learned it shows up as an AA skill under the class section. Make a hotkey and put it in a hotbar.
Have 10 bars of Dwerium in your inventory. Click the hotkey and wait for 10 enchanted bars to pop into your cursor.
You can do this again after you wait 8 hours. You can click on the AA description in the AA windows and see how much time is left on your timer.
