belgianbrewer... There are a myriad of videos out there, some on youtube, showing simple spark testing with a hand-held grinder to differentiate various metals. I recall one by a fellow posting welding videos, "chucke2009". Check out this video where he compares mild steel with cast irons. I think he may also have others showing testing of other steels.

I am a newbie to blacksmithing, and often overwhelmed with what seems to be an unending variety of ways to forge things, tools, etc. I was aware that there are many, many forms of hammers being used by smiths and since it probably is the most important tool aside from our anvils I need to learn the various uses of those hammers. After watching Brian's video, I have a much, much better understanding of the importance of the rounding hammer, it's many "surfaces" and the ways to utilize them. The video clearly explains the versatility of the rounding hammer and that it's not just a "neat looking hammer". Brian's video really made an impression on me and gave me a new insight into forging things. Great video and instructions, Brian!!!
