Quantfire Ceramic Plate Setter for 18" Kamado — Heat Deflector & Pizza Stone, Thick Heat-Retaining Ceramic

The Quantfire Plate Setter is a ceramic heat deflector designed to convert your 18" kamado into an indirect-heat oven and pizza-friendly stone for more even cooking and crisper crusts.

Built to replace or upgrade the standard convEGGtor, this Quantfire Plate Setter serves as a versatile heat shield and ceramic baking surface for large Big Green Egg-style grills. It creates a stable radiant heat zone between flames and food, letting you roast, smoke, bake pizza, and finish delicate items without flare-ups or hot spots. The plate’s thick ceramic construction holds and disperses heat evenly, while its dimensions are tailored for 18" kamado grills to fit securely and maintain efficient airflow.

How does this plate setter help when I want to smoke or roast?

By separating the fire from the food, the Quantfire plate setter provides indirect heat that mimics an oven environment. That prevents direct flame contact and reduces the risk of burning, while allowing low-and-slow temperature stability for smoking and roasting.

• Creates a reliable radiant heat barrier for consistent long cooks
• Reduces flare-ups and direct-hot-spot contact with food
• Maintains steady temperatures ideal for smoking ribs and whole chickens
• Fits 18" kamado grills without gaps that disrupt airflow

Can I use it to bake pizza and get a crisp crust?

Yes — the Quantfire plate setter doubles as a ceramic pizza stone that stores heat and transfers it to the dough for a crisp, evenly browned bottom. Its dense ceramic surface absorbs and radiates heat quickly when preheated, producing the high floor temperature needed for artisan-style pizzas.

• Thick ceramic surface for strong heat retention and crisping
• Large diameter fits 18" kamado fireboxes for full pizza clearance
• Preheats to deliver uniform base browning without burning toppings
• Works with pizza peels and other kamado pizza accessories

Will it replace the factory convEGGtor and how do I install it?

The Quantfire Plate Setter is designed as a drop-in replacement or upgrade for most 18" kamado convEGGtors. Installation is straightforward: lift the old heat deflector, set the ceramic plate in the firebox or on the manufacturer’s supporting rings, and check that vents and grate positions allow proper airflow.

• Dimensioned to match 18" kamado mounting and support rings
• Simple drop-in installation with no tools required
• Compatible with standard grilling grates and second-level racks
• Removeable for direct grilling when desired

How should I care for and maintain this ceramic plate setter?

Ceramic components benefit from gentle handling and gradual temperature changes. Allow the plate to cool before cleaning, avoid thermal shock from rapid temperature swings, and clean with a soft brush or scraper; heavy detergents are unnecessary for routine barbecue residues.

• Cool completely before cleaning to avoid cracking
• Use a grill brush or scraper to remove stuck-on food
• Avoid drastic cold-water cooling after high-heat use
• Store inside or under cover to reduce exposure when not in use

Who is this for: The Quantfire Plate Setter is aimed at kamado owners who want more versatility from their 18" grill — home chefs who bake pizza, pitmasters who smoke low-and-slow, and anyone seeking a durable upgrade to their factory heat deflector. If you regularly roast whole poultry, bake artisan crusts, or need steadier indirect heat, this ceramic plate setter delivers stable temperatures, even heat distribution, and straightforward installation for everyday backyard cooking.
