The plus side, and the minus

Strengths

  • Publishes both dimensions — 15 × 11.8 in (38 × 30 cm)
  • Rectangular rather than round: more usable area on a rectangular shelf
  • Stated heat-resistant to 1,652 °F (900 °C), so a charcoal grill is within range
  • Natural cordierite, stated to spread heat evenly

Compromises

  • No thickness published — the figure that decides thermal mass
  • Hand cleaning only
  • Not sold on Amazon.com: the button runs a search instead
  • 15 in (38 cm) will not fit most mini ovens

15 × 11.8 inches (38 × 30 cm)

Published, and rectangular. Both matter: a rectangular stone uses a rectangular oven shelf better than a round one, and a published dimension is the only way to know it fits before it arrives.

Leave air at the sides. An oven circulates around its shelf, and a stone cut to the exact internal width blocks the path it was meant to help.

1,652 °F (900 °C)

Blumtal states the natural cordierite is heat-resistant to 1,652 °F (900 °C) and distributes heat evenly. That ceiling puts a charcoal grill within range, not just a domestic oven — which is what the stone is for as much as pizza.

What is not published

Thickness. A stone is bought for thermal mass, and thickness is how it is measured: a thin stone gives its heat to the first pizza and has none for the second. On this shelf the Unicook cordierite stone publishes 0.6 inches; this one publishes nothing.

Cleaning

By hand, per Blumtal, which states the surface is robust enough for it. Stones are not washed with detergent — that is the general rule for the material and the manufacturer’s instructions govern yours.

Buying it in the United States

Blumtal sells this stone on the German, French, Italian and Spanish Amazon stores, and not on Amazon.com, so the button on this page runs a search instead. The closest American equivalents on this shelf are the Unicook, a cordierite stone of 15 × 12 inches that also publishes its thickness, and the Ritual Life 15-inch rectangular cordierite stone.

What readers want to know

Will it fit my oven?

It measures 15 × 11.8 in (38 × 30 cm), and that is the figure to hold against your shelf — leaving room for air at the sides. A stone cut to the exact internal width blocks the circulation it was meant to help. Most mini ovens on this site are too small for it: the Rommelsbacher BG 1805, the only one that publishes what fits inside, takes tins up to 12.4 in (31.5 cm) across.

How thick is it?

Blumtal does not publish a thickness, and it is the specification that decides thermal mass — how much heat the stone stores, and therefore whether the second pizza is as good as the first. On this shelf the Unicook cordierite stone publishes 0.6 in; this one publishes nothing.
