Probably should ask the author, but a yellow flame is sooty. It will leave fine black carbon layer on the flask which will make it impossible to see what is going on inside. It wipes off easily enough at the end, of course.

Hi all--We're considering this potassium mirror video for C&EN's #RealTimeChem Week Awards. Any safety concerns we should consider?
