What is the largest piece of metal that has ever been cast as a single
part? I would like a reference to the claim that it is the largest in
the world. The largest casting that I am aware of is  312 tons, but
the reference only claims that it is the largest in China.

I would like a credible claim to the largest casting in the world, but
if that proves too difficult, I will accept the reference to largest
casting the is greater that the one above.

"...The image of the Great Buddha (Buddha Vairocana), the world's
largest casting, at the Daibutsuden Temple in Nara, is 16.19 meters in
height. In order to cast this image, 443.7 tons of bronze was used..."


What do you think?

Ooops.  I think I spoke too soon.

The Buddha, large though it is, is not cast as a single piece.  

I'll keep looking, though...
