Basically there are two types of blasting caps. One is electric and the other uses a burning fuse. It is somehow fishy that the stick seems to have been stored with cap and fuse. So it is hard to tell how long the fuse was. On top there are fuses with different burning speeds. A short fuse may burn for several seconds.
Most people should have experience with candles. If it does not feel like a candle it may be a bad idea to set it on fire in the first place.
