How to identify good quality incense
Always go to a reputed store in your locality to buy incense stick
Ask for a good brand.Just take one of incense stick out and light it at the tip and smell it from a distance.Never inhale incense smell from a close distance.fragrance of good quality incense will reach long distances.Another way to identify is to leave incense burning.A good quality incense will last around one hour.
incense is mixture of armoatic substance and oil.Aromatic substance have significantly lower boiling point than oil.When heated together in form of incense,aromatic substance evaporates instead of burning.So a good incense lasts around one hour and gives you nice fragrance as it is evaporating not burning.
If petroleum byproduct is used instead of natural oil than it has very near boiling point to armomatic subtance.It will lead in burning of aromatic substance instead of evaporation.So it will burn quicly and produce CO2.
