COMVIEE Half-Moon Cordierite Heat Deflector Plates for Kamado Joe 18" — White 2-Pack, Indirect Cooking Durable Ceramic

These are COMVIEE half-moon cordierite heat deflector plates designed to convert an 18" Kamado Joe into a reliable indirect cooking setup.

Swap in these two white cordierite plates to create a stable, high-heat-resistant barrier between charcoal and food, enabling even roasting, baking and low-and-slow smoking on Classic I, II or III Kamado Joe grills. Sintered at extreme kiln temperatures and formed to fit the Divide & Conquer system, they’re built for repeatable temperature control and long-term durability without imparting odors or contaminants.

How do these plates change how my Kamado Joe cooks?

Installing the COMVIEE half-moon deflectors creates an indirect cooking zone that reduces direct flame contact and evens out heat across the grate. This makes delicate tasks like baking or slow-roasting far more consistent than direct grilling alone.

• Creates a shield between coals and food to prevent hot spots
• Promotes gentle, radiant heat ideal for bread, pizza and roasts
• Works with Divide & Conquer grates to build two-zone setups

What material are the plates made from and why does it matter?

The COMVIEE deflectors are forged from food-grade cordierite and sintered in a 2100°F kiln, producing a dense ceramic that holds heat and resists cracking under temperature swings. That composition helps maintain steady cooking temperatures and prevents flavor contamination because it contains no harmful additives or odors.

• Cordierite ceramic provides strong thermal shock resistance
• Retains and radiates heat for consistent cooking results
• Food-grade, odor-free construction is safe for repeated use

Will these fit my Kamado Joe Classic I, II or III and how do I set them up?

Yes — the pair is sized to fit the 18" Kamado Joe Classic I, II and III and integrates with the Divide & Conquer Flexible Cooking System. Installation is straightforward: place the half-moon plates on the lower ring to form a full circle or configure them to create a two-zone layout for combined direct and indirect cooking.

• Two half-moons form a complete indirect surface when paired
• Compatible with Divide & Conquer grates and multiple rack positions
• Simple placement; remove and soak for easy cleaning after use

How do I care for the deflector plates to keep them performing?

Care is minimal: after the plates cool, soak them in warm water and gently scrub with a sponge or soft brush; soap is usually unnecessary. Avoid sudden extreme temperature shocks and handle them carefully to prevent accidental drops or impacts.

• Allow plates to cool fully before cleaning
• Soak in warm water and scrub gently — no harsh detergents needed
• Store in a dry place to prevent dust buildup between uses

Who this is for: home cooks and outdoor chefs who want to expand their Kamado Joe’s capabilities — especially bakers, pitmasters, and anyone who wants more reliable indirect heat for multi-level cooking. These plates suit owners of the 18" Classic models looking for a durable, food-safe replacement or upgrade for indirect and two-zone cooking setups.
