Product Description

Indirect Barbeque, Two-Zone Grilling & Pizza Baking

The CGS 16" ceramic deflectors are available as a pair of half-moon heat deflectors or as a full-round pizza stone, giving you options for indirect barbeque, two-zone grilling and pizza baking.

Use a pair of half-moon deflectors with compatible CGS and grill-manufacturer rack systems to create full indirect coverage for smoking ribs, brisket, pork butt, chicken or sausage.

Use a single half-moon to create direct and indirect cooking zones. This creates a lower-temperature area for holding or staging food while grilling.

The full-round stone is best used as a pizza stone but can also provide indirect coverage in specific rack setups. For pizza, the 16" stone is recommended for grills with a 20" or larger diameter cooking grid.

Before Ordering: Fitment and positioning depend on the grill and rack system being used. Check the manufacturer details or applicable CGS grill or rack-system product page for the recommended deflector size, support position and setup details.

Why Choose Half-Moon Heat Deflectors?

Half-moons give you more flexibility than a single full-round deflector.

  • Two-zone grilling: Use one half-moon to create direct and indirect cooking zones
  • Full indirect barbeque: Combine two halves for complete indirect coverage
  • Compatibility: Pair half-moons with other accessories on the same rack level
  • Easier handling: Two smaller pieces are easier to handle and store
  • Lower replacement cost: If one half breaks, you only need to replace that piece
  • Easier fire access: Remove or reposition one half to reach the charcoal during a cook
Setting Up the Full-Round Pizza Stone

For pizza cooks, position the full-round pizza stone above a separate heat deflector with an air gap between the two ceramic surfaces. The lower deflector blocks direct heat from the charcoal, while the elevated stone provides the baking surface.

For even heating, use a lower blocking stone that is at least as large as the baking stone. Position the baking stone high in the dome, while staying clear of the thermometer stem.

Use cornmeal or parchment paper between the dough and stone to help prevent sticking. Check the applicable CGS grill or rack-system page for the recommended deflector size, spacing and stone height.

Using a Drip Pan

For barbeque cooks, we strongly recommend placing a stainless steel drip pan above the ceramic heat deflector.

Ceramic is porous and can absorb grease and moisture. Reheating trapped moisture can create steam inside the ceramic and place additional stress on the stone.

Double-wrap the drip pan with foil in a '+' pattern. This makes cleanup much easier.

Benefits of Ceramic Spacers

CGS Ceramic Spacers create an air gap above the heat deflector and can improve your setup in several ways:

  • Under a drip pan: Helps reduce scorching and burnt drippings
  • Between deflectors: Creates separation in double-indirect setups
  • Under a pizza stone: Adds lift and creates thermal separation between the deflector and baking stone

Care & Maintenance
  • Do not use soap, detergents or chemical cleaners on the porous ceramic.
  • Do not clean the ceramic in a dishwasher or submerge it in water.
  • Scrape away food debris and gently burn off remaining residue at moderate temperatures as needed.
  • Avoid extreme high-heat cleaning burns, which can damage the kamado.
  • Expect the natural ceramic surface to darken with normal use.
Frequently Asked Questions

Will these 16" deflectors fit my grill?

Fitment depends on both the grill and the rack system. Check the applicable CGS grill or rack-system product page to confirm size and positioning.

Do the deflectors require a rack?

Yes. When used as heat deflectors, the ceramic pieces require a compatible Woo, Spider, rack or other support that positions them securely inside the grill. Check the applicable grill or rack-system page for the recommended setup.

Can the half-moons be used as both a deflector and pizza stone?

Yes. A pair of 16" half-moons can be used as a pizza stone, as long as your rack system can properly position and support them.

Will the ceramic darken with use?

Yes. Ceramic deflectors and pizza stones naturally darken as they are exposed to smoke and cooking residue. This change is normal and does not affect cooking performance.

Can I clean the ceramic with a high-heat burn?

We do not recommend aggressive high-heat cleaning burns. Scrape away loose debris and gently burn off residue at moderate temperatures. Using a drip pan helps prevent heavy grease buildup.
