Derurizy Half-Moon Ceramic Heat Plates for Kamado Joe — 2×15" Cordierite Deflectors for Even, Multi-Zone Cooking

Derurizy half‑moon ceramic heat plates are two 15" cordierite deflectors that create reliable indirect and multi‑zone heat for Kamado Joe Classic I, II, III and compatible grills.

These two half‑circle ceramic plates replace worn or missing heat deflectors and let you set up flexible cooking zones on your kamado or compatible BBQ. Built from food‑grade cordierite, the plates store and radiate heat evenly for low‑and‑slow smoking, even roasting, and high‑temperature baking like pizzas. They are designed to pair with Divide & Conquer style cooking grids and fit most 15‑inch kamado domes and ovens that accept half‑moon inserts.

How do these plates change the way I cook on a kamado?

The half‑moon design lets you run direct and indirect heat at the same time, so you can sear foods over open flame while slow‑roasting on the deflected side. Ceramic holds and reflects heat, smoothing temperature swings and improving fuel efficiency.

• Create dual cooking zones for searing and low‑and‑slow on one grill.
• Even heat distribution reduces hot spots for consistent results.
• High heat retention keeps stable temperatures for long cooks.

Will these fit my Kamado Joe Classic I, II, or III?

Yes — each plate is sized to work with 15‑inch kamado systems that accept half‑moon deflectors, including Classic I, II and III. They also suit many grills and ovens that use 15" ceramic inserts or flexible cooking systems.

• Two 15" half‑moon plates per pack to rebuild a full circular deflector.
• Compatible with Divide & Conquer and similar flexible racks.
• Check dome diameter and grate layout for confirmed fit.

What materials and care do these ceramic plates require?

Manufactured from food‑grade cordierite, the plates resist thermal shock and tolerate high temperatures without releasing odors or harmful compounds. They become naturally seasoned with use; avoid oiling or pre‑seasoning and clean gently to preserve the surface.

• Made from high‑temp, food‑grade cordierite for durability.
• Hand wash with warm water only; avoid soaps and harsh scrubbers.
• Staining and darkening are normal and help build a nonstick surface.

Can I use these for pizza and other baking on my grill?

Yes — the heat plates act like pizza stones when configured to create a hot, radiant cooking surface. They help crisp crusts and deliver even bake results when you convert your kamado or oven into a high‑heat baking environment.

• Use as a pizza surface or to convert grill into a pizza oven alternative.
• Handles high temperatures needed for crisp, evenly cooked pizzas.
• Works equally well for breads, roasts, and slow‑smoked dishes.

Who is this for: These Derurizy half‑moon ceramic deflector plates are made for kamado owners and grill enthusiasts who need a reliable way to set up indirect heat zones, replace old or damaged deflectors, or expand their grill’s baking capability. If you own a Kamado Joe Classic I, II, or III (or another 15" compatible system), and you want improved heat retention, better temperature stability for long smokes, or a way to bake pizzas and breads on the grill, this two‑pack is a practical, durable solution. They suit backyard pitmasters, weekend grillers, and anyone converting their barbecue into a more versatile cooking appliance.
