Natural hookah coals are the preferred hookah coals of experienced smokers. Hookah Wholesalers offers coals made from lemon wood, olive wood, and even coconut shell. Natural coals do not use an accelerant to ignite the coals, so there is no residual flavor from fast lighting chemicals. Traditional coals need a heat source such as a stove or open flame to ignite. After a few minutes they will begin to glow red all over, signifying they are ready for use. Natural coals tend to last longer and are generally less expensive by volume.
