We do not use chemical additives designed to improve the ignition of coal, increase its strength in the cold state or when burning. Therefore, VUGO does not emit an unpleasant odour during ignition and burning. The high content of pure carbon and the high density of the cube contribute to the long burning of coal in a hookah. When smoking hookah, there are only the taste and smell of tobacco, without any impurities coming from the coal. The purity of our product expects no headaches, which often accompanies when in use with low-quality coals.

The ash content of coal is determined by the amount of non-combustible substances in the coal cube such as calcium, potassium, silicon and others. The calcium content in walnut coal is higher than in coconut coal. That is because, the natural features of walnut trees are to pull calcium from the ground for their needs and then it is transferred to the shell. This leads to the fact that the total ash content in our coal is slightly higher than in coconut. We could use certain chemicals to slow down the release of the ashes, but since we are specifically working without chemicals this is out of the question for us. We are marketing a natural product and so the release of the ash is a natural process, however we are working to find a way to minimize this process.

The amount of heat released by coal depends on the content of pure carbon in it, the density of the cube and its moisture. Depending on intensity of smoking, 2 cubes of VUGO coals in kaloud should be enough heat to enjoy hookah for one hour. To improve the heat of our coals we recommend tapping off the ash every 15 minutes.

VUGO's burning time is not inferior compared to the best samples of coconut coals.
