A Mitsubishi Materials press release (Japanese) announces that the company has cast the world's largest gold bar. The 250kg bar is pictured above alongside a more typical 1 kilo bar. If beaten out into gold leaf, the gold would cover an area of 70,000 tatami mats (over 2.6 Tokyo Domes). The company's previous record, a 200kg bar, was beaten by a Taiwanese company's 220kg effort last year. Mitsubushi Materials has immediately applied to the Guinness Book of Records for recognition.
