Talk:Jet black candle

blue flames
Pottermore states that the presence of a ghost can turn flames blue. Given this, I don´t think that this candles generally have blue flames.

Furthermore, in the muggle world, the colour of a flame has to do with its temparature, indicating that the presence of a ghost makes flames hotter.--Rodolphus (talk) 04:29, September 24, 2014 (UTC)
