What are Hex Coals?

Hex coals are hexagon-shaped coconut charcoal — the same natural coconut shell coal you'd find in cubes, just pressed into a six-sided stick instead of a block. Each piece has six flat sides running the length of the coal, plus two flat ends.

They're bigger than cubes. A standard cube runs around 26mm square. A hex is typically 22mm across the six faces but 40 to 51mm long — so while the cross-section is narrower, the total coal is larger and heavier. That extra length means more burn time and a longer session off fewer coals.

The shape does specific work on foil. The flat sides sit flush against the foil without rolling, which is hex's first real advantage — arrange them around a bowl and they stay put. Because the coal's weight is spread along the length rather than concentrated down through a single cube corner, hex coals press less sharply on any one spot of foil — less risk of a localised sag or burn-through. Heat spreads more evenly across the bowl edge.

If you use a Kaloud Lotus or other HMD, skip hex — the stick length doesn't fit HMD baskets, which are built around cube dimensions. Hex is the foil and heat screen specialist.

Also known as: hexagon charcoal, hex charcoal, hexagonal coals, six-sided coals, hex sticks.

About this collection

Hexagonal coconut shisha charcoal built for a steady, controlled session. The six sided shape sits flat on the heat management device and packs tightly in the coal burner, so each coal lights evenly and holds temperature longer than round cubes. Clean burning coconut shell coals mean low ash, minimal odour and a neutral heat that lets the bowl do the talking.

These hex sticks run roughly 20 to 23mm wide and around 40 to 48mm long, so a single stick covers more of the bowl than a standard cube and needs fewer coal changes across a session. Reach for hex over cubes when you want fewer light-ups and a flat, stable coal that will not roll off the foil or the screen. Our range includes hexagonal coconut charcoal from Cocoshisha Titanium, Cerberus Coco, ZEUS, TOM and Naara, in single boxes and bulk lounge packs.

Hexagonal shisha coals: common questions

How long do hexagonal shisha coals burn?

A hexagonal coconut coal typically holds usable heat for around 60 to 90 minutes once fully lit, longer than most cubes because the stick carries more mass. Burn time varies with airflow, coal size and how many you run.

Hex coals or cube coals?

Hex sticks give you a longer burn and a flat base that sits stable on a foil or heat screen, so they are the pick for longer sessions and fewer coal changes. Cubes are quicker to light and easier to space out on a three-coal setup. Many smokers keep both on hand.

Do hexagonal coals fit a heat management device?

Yes. The flat six sided profile sits neatly inside most HMDs and closed heat managers, and it also works on a poked foil setup. See our heat management range to match a device to your bowl.

Common questions · Hexagonal Coals

Are hex coals better than cubes?

Neither - they suit different setups. Hex coals are the better pick for foil and heat screen sessions: they sit flat without rolling and their length lets them spread heat evenly around the bowl edge. Cubes are better for HMDs because the basket shape is built around cube dimensions. Hex coals are larger and heavier per piece - so one hex usually replaces what two cubes would do.

How many hex coals do I need for a session?

Two to three is the usual count for a standard bowl on foil or a heat screen - arranged around the edges, not stacked in the middle. Because hex pieces are bigger than cubes, you use fewer of them. Start with two for a shorter session, three for a longer one. Easier to add a coal than to cool one down.

How long do hex coals burn?

Longer than a standard cube - typically 90 to 120 minutes per piece, because hex coals are physically larger. Exact burn time depends on the brand, airflow, and how you rotate them. Turning the hex every 15 to 20 minutes so a fresh face takes over the heating extends the usable heat across the full session.

Do I need to light hex coals differently than cubes?

Same process but slightly longer. Light on an electric coil burner for 7 to 10 minutes until all six sides are glowing red, flip once to make sure both ends are lit, then place on the bowl. Hex coals take a minute or two longer than cubes because there's more coal to ignite. Never use a gas stove or open flame directly - chemical residue affects flavour.

Can I use hex coals inside a Kaloud Lotus?

Not ideally. The Lotus basket is built around cube dimensions - hex coals are too long to fit and don't contact the heat plate evenly. For HMDs, stick with 26mm cubes or purpose-made HMD-shape coals like quarter-circles (Al Duchan Ypsilon fits that category). Hex belongs on foil or under a heat screen.

Does the brand of hex coal matter?

Somewhat. The shape does most of the work - all hex coals give similar airflow and heat spread. What changes between brands is ash content (less ash = cleaner session), burn time consistency, and how well the coal holds shape as it burns down. Shaman and Cocourth are reliable picks. Stock up on a bundle of the brand you like rather than mixing.
