Much delayed starting in the cold greenhouse this year and finally builders have finished and the portaloo across the door has gone.
So I cleared the winter detritus and lit a sulphur candle this eveninf once the vents had closed.
Opened the paint tin holding the "candle" and following instructions unearthed the end of the yellow touchpaper from the "lentils" of sulphur and lit it.
It burnt down to the sulphur and went out.
Tried again, same result.
Any suggestions on getting it to light properly?
