Dongftai 15-inch Ceramic Heat Deflector Plate Setter — Pizza & Smoking Stone for 15" Kamado

The Dongftai 15-inch Heat Deflector is a solid ceramic plate setter that converts 15" kamado grills into efficient indirect smokers and pizza ovens for even, controllable cooking.

Designed for medium kamado-style cookers including 15" Big Green Egg and similar grills, this dual-purpose ceramic disc stabilizes internal temperatures while also serving as a pizza or baking stone. Its 15.5" overall diameter and robust ceramic construction provide steady heat distribution, making it a practical replacement or upgrade for worn or missing plate setters. Compact, durable, and universally compatible with most 15" kamado grates, the Dongftai plate setter helps you expand what your grill can do—from low-and-slow smoking to high-heat stone-baked pizzas.

How does this heat deflector control temperature for low-and-slow cooking?

The Dongftai deflector creates a barrier between coals and food so heat moves around the cooking chamber rather than blasting directly upward. This lowers the effective cooking temperature and smooths out hot spots for more consistent results over longer cooks.

• Ceramic thickness absorbs and re-radiates heat for gradual temperature change.
• 15.5" diameter matches standard 15" grates to reduce gaps and uneven flow.
• Stable structural design resists cracking under typical grilling and smoking cycles.

Can I use it to bake pizzas or bread on my 15" kamado?

Yes — the flat, high-density ceramic surface works as a pizza stone, producing a crisp bottom and even bake when preheated. Its heat-retaining qualities mimic a traditional stone oven, enabling quick browning and steady crust development when the grill reaches higher temperatures.

• Preheat thoroughly to reach consistent stone temperature before baking.
• Use a peel and a light dusting of flour or cornmeal for easy food transfer.
• Suitable for artisan pizzas, flatbreads, and rustic loaves on a kamado setup.

Is this Dongftai plate setter compatible with my medium-sized kamado?

It’s built to fit most 15" diameter cooking grills, including medium Big Green Egg models and comparable kamado brands. The standardized sizing and round profile minimize installation gaps so the plate setter integrates with existing grill hardware.

• 15.5" overall diameter tailored for 15" cooking grates and rings.
• Works as a drop-in replacement for worn factory plate setters or stones.
• Versatile for grills used as smokers, ovens, or conventional indirect cookers.

How do I care for and maintain this ceramic cooking stone?

Cleaning and maintenance are simple: brush off food residue and heat to burn off oils, then cool before rinsing if needed. Avoid sudden temperature shocks—let the stone preheat with the grill or cool slowly to prevent thermal stress.

• Brush or scrape after use, and perform periodic high-heat burns to clean oils.
• Never plunge a hot stone into cold water; allow gradual cooling.
• Store in a dry place when not mounted in the grill to prevent moisture absorption.

Who this is for: Outdoor cooks who want to expand a 15" kamado grill’s capabilities will benefit most from the Dongftai 15-inch Heat Deflector. It’s ideal for backyard smokers aiming for steady indirect heat, home pizzaiolos seeking a reliable stone surface, and anyone replacing a damaged plate setter on a medium kamado. If you own a 15" cooking grill and want a durable, multi-use ceramic accessory that improves temperature control and baking performance, this model is a practical, cost-effective choice.
