✔ 最佳答案
bunsen burner 一般燒到copper ion 就會有綠色既flame color(而唔係copper metal)呢一個實驗叫做flame test
另外, bunsen burner strike back 既時候都會有綠色既flame
strike back 即係開煤氣喉既時候唔記得將air hole完全關上
令到bunsen burner 產生綠色火焰同埋尖銳的聲音

It maybe due to the substance you burnt.
When copper ions are heated by the flame,
it will turn the flame into green colour.
