Ok, it can be done, but to what purpose?

I know, it was a bot post, but still why?

It is an "artsy" thing. Imagine it all polished and installed someplace where you would expect to just see a plain cast iron grate.

The very end shot at 28 seconds, there's a gap between these dissimilar metals, to where I think the grate is in two pieces.

The difference in pouring temperatures and shrink rates would make it very difficult for those two metals to remain physically join at their intersection. In the finished casting (on the left) the top was much cooler when poured than the bottom section.

I am very curious what those two metals are!! When I first saw the pour, I thought is was iron and copper. But that does not fit the colors of the finished casting.

During the pour, (right image) the bright glow of the top right indicates a much hotter temperature (1000˚c , 1800˚f) than the than the dull blackness of the lower left corner. (less than 1200˚f, 650˚c)

Left image was face down down when poured. Right image is as poured

At the beginning to the video, there are pallets that say "Hayes Metals"

So, I decided to look up "Hayes Metals" and lo and behold, it is a foundary operation in NZ:

They do all kinds of alloys. It looks like this might have been some kind of test/experiment/who knows pour to show off what they do... They pride themselves on their quality...
