This is my favorite steel ingot mold! I have been using it for many years and it does the job beautifully. It hold 4 ounces, which is plenty for my needs. Most ingot molds are way too big and too heavy to heat properly to get a good pour. For a person with only one torch, you need a small one like this for successful pouring. Besides, who are we kidding, when are we pouring something crazy like 10 ounces at once?! Good luck milling that!
