Here, I have listed several important technical indicators of hookah charcoal for your reference when producing or using hookah charcoal.
Cubic shisha charcoal
Hookah charcoal should be hard enough to prevent cracking when deashing or holding with pliers. You can test its hardness by stepping on it. Place the hookah charcoal under your heel and onto the hard floor, lift one foot, and slowly step on the hookah charcoal. If the shisha charcoal is being crushed easily in this process, it means that the hookah charcoal is not hard enough, which is not a good choice for hookah smokers.
Coconut charcoal generally has a higher density greater than 1.3, which means its specific gravity is greater than water. You can distinguish if the hookah charcoal is made of coconut shell by putting it in a glass of water. Real coconut shell charcoal will sink into the water because of its specific gravity. High-quality hookah charcoal will remain intact in water, and low-quality charcoal will be dissolved.
Time to ignition
The time required to ignite the charcoal with a gas stove or electric coil should be 7-10 minutes. When you find almost all its surfaces are covered with a thin layer of ash, the charcoal is ready to use.
Cubic hookah charcoal
Hookah charcoal can usually burn continuously for more than an hour. For example, a 25 × 25 × 15mm flat-shaped shisha charcoal should be sufficient for burning more than 60 minutes. The 25 × 25 × 25mm cubic shaped charcoal can continue to burn for more than 90 minutes.
Good hookah charcoal has the following characteristics:
1. Temperature and flame stability: 40-45 minutes
2. Hardness: Hookah char is not easily broken when burning
3. Surface temperature: about 320 ° C (608 ° F)
4. Medium temperature: about 350 ° C (662 ° F)
7. No flame
E.P Machinery has a unique charcoal powder density technique, which can ensure the hookah charcoal tablets produced have a certain hardness and burning durability.
