According to the color, the temperature should be higher than 800 °C (see https://en.wikipedia.org/wiki/Incandescence). The melting point of Pu is well below this value (see https://en.wikipedia.org/wiki/Plutonium), so I doubt that this is pure Pu. It should rather be the more stable PuO2 with a melting point well above 2000°C (https://en.wikipedia.org/wiki/Plutonium(IV)_oxide). — Preceding unsigned comment was added by 134.100.111.78 (talk) 19:22, 29 November 2016 (UTC)
