The hookah is a study in thermal dynamics, tracing from its 16th-century origins in the Mughal Empire to the precision-engineered systems of today. Discover how the interplay of 304 stainless steel, borosilicate glass, and laminar airflow transforms a traditional ritual into a calibrated vaporization experience.

A hookah is a water pipe that heats flavored shisha with charcoal and draws the resulting smoke through water before it reaches the hose. It is widely traced to 16th-century India. Modern hookahs use controlled heat, steady airflow and heat-stable materials to keep the shisha in Kaloud's target range of 130 to 220°C.
How does a hookah session work?
- Flavored shisha is packed in the bowl.
- Charcoal, usually on a heat management device, heats it from above.
- As the shisha heats, glycerol, water and flavor compounds form an aerosol.
- The aerosol travels down the stem into the water base.
- The water cools it.
- The hose delivers it on each draw.
Each draw creates negative pressure that pulls air through the charcoal and the bowl. That airflow also feeds the coals oxygen, which raises their heat.
Where did hookah originate?
The hookah is widely traced to 16th-century India under the Mughal Empire. The court physician Hakim Abul Fateh Gilani is often credited with passing tobacco smoke through water. Early versions used coconut shells as bases and hollow stalks as stems.
The design traveled through Safavid Persia, where glass bases and engraved metal stems appeared, and into the Ottoman Empire, where the hookah became a fixture of coffeehouse social life. Those developments set the basic form of the modern hookah.
What are the parts of a hookah?
- Bowl: holds the shisha and spreads heat through it.
- Heat source: charcoal, usually on a heat management device, or foil.
- Stem: the main airflow channel from bowl to base.
- Water base: cools the smoke.
- Hose: the draw path to the user.
- Tray: catches ash.
- Purge valve: lets stale smoke out of the base.

What does the bowl do?
The bowl is where heating happens. It absorbs heat and spreads it across the shisha. Clay has high thermal mass, so it takes heat slowly and releases it evenly. Glazed ceramic resists moisture. Stone and engineered composites hold heat for longer sessions. The bowl and heat management device work as one thermal unit.
How do traditional and modern materials compare?
| Traditional | Modern | |
|---|---|---|
| Examples | Clay bowl, wood stem, leather hose | Stainless steel stem, borosilicate glass base, silicone hose |
| Heat stability | Natural materials change with repeated heating | Hold their shape through repeated heat cycles |
| Flavor | Leather absorbs flavor | Silicone and steel are non-porous |
| Durability | Wood and leather wear out | Steel and borosilicate glass resist corrosion and heat stress |
How does water filtration work?
Smoke travels down a submerged downstem and bubbles up through the water. Three things happen at once: the water absorbs heat, some heavier particles condense, and bubbling increases contact with the water. The smoke that reaches the hose is cooler. Water cools the smoke. It does not chemically filter it.
Why does heat control matter?
Charcoal gives its strongest heat right after lighting, then its output falls as ash builds. Without control, the top of the bowl swings too hot, then too cool. Kaloud targets 130 to 220°C at the shisha. Controlled studies of heated glycerol and propylene glycol have detected breakdown products from about 215°C [1]. For the full science, see What Temperature Should Shisha Be Heated To?
A heat management device holds the coals above the shisha and spreads their heat through metal. In three Kaloud in-house test sessions with a Lotus I+3, the hottest reading was 219.2°C [2].
Which three variables control a session?
- Heat input: charcoal output changes across the session and needs managing.
- Airflow: a steady draw keeps heat even. Hard draws spike coal temperature.
- Material response: materials with more thermal mass buffer heat swings.
For how coals behave, see Hookah Coals Explained.
What mistakes ruin a hookah session?
- Too many coals: pushes the top of the bowl too hot.
- Tight packing: restricts airflow and traps heat.
- Loose connections: let outside air in and thin the smoke.
- Low water: reduces cooling.

Frequently asked questions
What is a hookah made of?
Modern hookahs use stainless steel stems, borosilicate glass bases, clay or stone bowls and silicone hoses. Traditional hookahs used wood, brass and leather.
Where did hookah originate?
Hookah is widely traced to 16th-century India under the Mughal Empire. It spread to Persia and the Ottoman Empire, where glass bases and metal stems became common.
How does a hookah work?
Charcoal heats flavored shisha in the bowl. The aerosol travels down the stem, cools as it bubbles through water in the base, and reaches the user through the hose.
Does the water filter hookah smoke?
Water cools the smoke and some heavier particles condense in it. It does not chemically filter the smoke.
Why does my hookah taste burnt?
The top of the bowl is running too hot, usually from too many coals, coals in one spot or hard draws.
How long does a hookah session last?
It depends on bowl size, shisha load and heat control. In Kaloud's Lotus I+3 tests with 30 g of shisha, sessions ran 81 to 91 minutes [2].
