A pipe dream:
A perfectly clear clay tobacco-shisha bowl? Not yet invented (except for the semi clear acrylic bowls which cost a big $ bundle and break easily too).
So, how to tell if you smoked all the shisha in the bowl?
I guess its up to experience.
1) how much did you pack?
What is usually for you a half-hours smoke? 40 minutes went buy and your tongue is feeling fuzzy-you are long ago finished and if you have a good burning coal, you are getting plain heat and ashes taste.
2)did you pack loosly or too tight?
If tight it will burn for sure, mostly at the bottom.
3)type of shisha being smoked.
Al-Fakher, Al-Ouns ,Al-Qemah,Roman,Fumari,Afzal are loooong ongoing good smokes.
15 grams lightly packed of Al Fakher,Al-Ouns,Al-Qemah,Roman will approximately smoke 45-60 minutes.
The same ammount of Al-Waha, Al-Sultan, El-Nakhla,El-Basha
(same company) will smoke 20-30 minutes lightly packed.
If you have been going on longer, its a burn!
These are just a few hints.
4) when you’ve finished smoking EACH time look at what is left over.
If its ash, then next time don’t smoke that gram ammount too long. Or get a bigger bowl.
The gigantic “party bowl” which I mainly use is big enough for 30-35 grams, and since its bad to add shisha up to the top where it touches the foil and will burn, I still have room left over.
I always check the remains of any bowl to see if its over burnt. There should be left a bit of lightly cooked shisha at the bottom remaining.Throw it out!
With so many shisha brands out there herbal and regular, each company brand has its own burning time.
It depends mainly on how much glycerine is in the mixture.
You’ll find Nakhal is a dryer brand. The premium brands are dripping and smell so good even before you put them in the bowl!
