What Is Hookah Made Of? Materials That Control Performance
Written by: Reza Bavar | Research & Technical Contribution by: Vinny
Hookah performance is defined by materials, not appearance. This guide breaks down how stainless steel, aerospace-grade aluminum, and non-porous polymers control heat stability, airflow behavior, and flavor consistency.

A hookah is made of five main parts: bowl, stem, base, hose and the heat interface on top of the bowl. Modern hookahs build these from stainless steel, aluminum, silicone, non-porous polymers and borosilicate glass. The materials decide how heat is absorbed, stored and released, which decides whether the shisha stays in Kaloud's working range of 130 to 220°C.
What are the parts of a hookah?
- Bowl: holds the shisha, where heat is applied and vaporization starts
- Stem: the main airflow channel from bowl to base
- Base: the water chamber that cools the smoke
- Hose: the draw path to the user
- Heat interface: foil or a heat management device, where charcoal heat passes into the bowl
Traditional hookahs used wood, brass and leather. Wood absorbs moisture and swells. Leather hoses hold on to flavor. Brass tarnishes over time. Modern hookahs use non-porous, heat-stable materials that behave the same way session after session. For how the parts work together, see Everything You Need to Know About Hookah.
Why do materials matter for heat?
Materials control how charcoal heat reaches the shisha. Kaloud works to a 130 to 220°C range in the bowl. Above about 220°C, the glycerol and propylene glycol in shisha start to break down [1]. Four material properties decide how well a hookah holds that range. For the full temperature science, see What Temperature Should Shisha Be Heated To?
Thermal mass
High thermal mass absorbs heat during the charcoal's early peak and releases it as output falls. This smooths out spikes.
Thermal conductivity
High conductivity spreads heat quickly across a surface. Low conductivity slows heat transfer.
Thermal expansion
Materials expand when heated. Stable materials keep their shape through repeated heating, which keeps seals airtight and airflow steady.
Porosity
Non-porous materials do not absorb moisture or flavor compounds, so flavor stays clean and airflow paths stay clear.
How do materials control heat stability?
Charcoal gives its strongest heat right after lighting, then output falls as ash builds. Materials respond in three ways:
- They absorb excess heat at the peak
- They store it in their structure
- They release it as charcoal output declines
Heat moves by conduction, through direct contact with the bowl or device surface, and by convection, as each draw pulls hot air through the shisha. Materials with low thermal mass pass every change in coal heat straight to the shisha.
A study of a foil-covered waterpipe measured tobacco temperatures from 450°C nearest the charcoal down to 50°C furthest from it [2]. That gradient is what materials and heat management have to control. For more on the heat source, see Hookah Coals Explained.
Which materials are used in modern hookahs?
Stainless steel
Resists corrosion and keeps its shape through repeated heating. Its non-porous surface resists residue, so stems and internal parts stay clean.
Aluminum
Light, strong and quick to respond to heat. It machines to tight tolerances for consistent fit and airflow.
Silicone
Flexible, durable and non-porous. Silicone hoses and seals do not hold flavor the way leather and fabric do.
Non-porous polymers
Used for housings and structural parts. They are light, resist moisture and hold up under repeated heat.
Borosilicate glass
Used in Samsaris Vitria bowl inserts as the surface between heat and shisha. Its low thermal expansion lets it take fast temperature changes without cracking. It is non-porous and does not react with shisha.
How do hookah materials compare?
| Material | Key property | Behavior under heat | Where it is used |
|---|---|---|---|
| Stainless steel | Corrosion resistant, non-porous | Stable through repeated heat cycles | Stems, internal parts |
| Aluminum | Light, responsive | Transfers heat quickly | Precision parts, heat devices |
| Silicone | Flexible, non-porous | Does not absorb residue | Hoses, seals |
| Non-porous polymers | Durable, light | Resist deformation under heat | Housings, structure |
| Borosilicate glass | Low thermal expansion | Handles fast temperature changes | Bowl inserts |
How do surfaces affect airflow?
Airflow carries heat across the shisha. Smooth, non-porous surfaces let air move evenly. Rough or porous surfaces add resistance and uneven flow, which creates hot spots where parts of the bowl climb above 220°C. A steady draw through smooth channels keeps heat even.
How do materials affect flavor?
Porous materials absorb moisture, glycerin and residue from past sessions. That residue carries old flavors into new ones, often called flavor ghosting. Stainless steel, silicone and non-porous polymers do not absorb flavor compounds.
Uneven heat also damages flavor. Hot spots push parts of the bowl out of range and break down glycerin and flavor compounds. Materials that spread heat evenly release flavor gradually.
Clean surfaces keep this consistent. See how to clean a hookah properly.
How do Kaloud components work together?
Good components still underperform if they are not designed to work together. Kaloud designs its parts as one system: a Kaloud Lotus heat management device on a Samsaris bowl, on a Kaloud Krysalis hookah.
In three Kaloud test sessions with a Lotus I+3 on a tall black bowl with 30 g of shisha, the hottest reading was 219.2°C [3].
What material mistakes hurt performance?
- Low-quality metals: they corrode under repeated heat, add resistance and taint flavor.
- Porous parts: leather hoses and untreated materials hold moisture and old flavor.
- Poor thermal response: low thermal mass lets heat spike and drop.
- Rough finishing: rough internal surfaces disrupt airflow and create hot spots.
- Mismatched parts: one part holds heat while another loses it, so heat behaves unevenly.
Frequently asked questions
What is a hookah made of?
Modern hookahs use stainless steel, aluminum, silicone, non-porous polymers and borosilicate glass. Traditional hookahs used wood, brass and leather.
Why do materials matter in a hookah?
Materials control how heat is absorbed, stored and released. That decides whether the shisha stays within 130 to 220°C or runs hotter.
Is stainless steel good for a hookah?
Yes. It resists corrosion, keeps its shape under repeated heat and does not absorb flavor.
Why are silicone hoses better than leather hoses?
Silicone is non-porous, so it does not hold moisture or flavor. Leather absorbs both.
Why do some hookahs taste inconsistent?
Uneven heat, porous materials and residue buildup in the airflow path all change flavor from session to session.
