  1. Here's a quick question for an expert... I get a good bit of molten slag or scale in my forge. I've been forging meteorite iron and I'm not sure if the liquid in the forge is molten slag or molten scale or something else. I use to think it was excess borax from welding, however in my new forge I get a good amount of this molten material and I haven't used any borax flux. I typically scrape most of this liquid out while forging. I'm surprised how much there is. I keep the forge really hot because of the nickel content of the iron so I forge at welding temperatures pretty much all of the time. A couple of questions: 1. Is this molten slag or molten scale (or is that the same thing)? When it cools it's brittle with a much lower density than iron. Would meteorite cause more of this material than normal iron? 2. I forge welded some pieces of meteorite without using borax flux. I actually used the molten material to see if it would act as a flux and it squired out just like the borax flux does and it appears that I have a good weld. Have you ever heard of that before? Does this molten material help in anyway with a weld, or does it hurt the weld versus just cleaning the metal with a brush before putting it back into the forge to get it up to welding temperature? Thanks!!! James in Orlando, FL
