My math skills seem to be suffering today. Make that ten years.

Agnes hasn't been back on here for 20 years.

Silicon carbide measures 9.5 on the Mohs hardness scale. This would be one way of verifying it's authenticity. Do you have some hardness picks or access to some? Otherwise, if you calculate the density that could also determine what it is.

Half of a wing nut could make for ears. Half each side, of course.

I don't see anything but the text.

The OP is in Hawaii, friend is coming from Maine.

Are you taking a lot of Iron supplements?

The heating of those steels to quench will actually cause some decarburization. So, the quench in oil to add carbon would be a net loss to begin with. And really no carbon from the oil would go into solution with the metals. Processes that can add carbon to the metal's microstructure would be one like pack carburization. There are also carburizing compounds like cherry red, which uses a torch, I think to make the carbon transfer to the SURFACE. All these methods result in only surface hardening, known as case hardening.

What is the forge lining made from?

Hefty. The entire forge kit, burner and all. Hefty. The entire forge kit, burner and all. I checked again today, still 18 dollar coupon. Curious thing I noticed is that there is a review from Australia.

I just looked on Amazon and it shows it is still available...and with an $18 dollar off coupon today!

I think that it is hilarious that the skeletons' condition is listed as "used".

Gas forge or solid fuel?

Make sure that the power supply, or outlet which will power your proposed welder is adequate. I was really close to buying a flux core welder when I read on the box that it requires a dedicated 20 Amp outlet. Power to my shop is supplied from an extension cord, so no welder for me yet.

The forge that you made looks well made. With the burner being top dead center it may be that there is heated air (Oxygen) impinging upon your steel, resulting in the scaling you mentioned. Some of the folks here recommend a 'D' shape or oval with the flame pointed at the sidewall or far floor, from the top or side mount, like 10 or two o'clock. If you made another, 2" of the insulating blanket will help. Too bad about the lack of Mr. Volcano being on your version of Amazon. The whole kit is only $88 US. The burner, wool, refractory, hoses, you name it. I bought a second one, single burner forge. Personally, I am wary of Vevor stuff. It seems to me that they sell anything and everything. That makes me think that they will slap their brand name on stuff from many other manufacturers and sell it as their own. Just my personal opinion on that.
