Choosing The Ziola Pizza Stone
WHICH STONE IS RIGHT FOR YOU? CORDIERITE VS. BISCOTTO FOR THE ZIOLA
Choosing the right baking stone matters. It dictates how your pizza cooks, how consistent your results are, and—frankly—how much control you have over the thermal behaviour inside your Ziola. Most customers assume “a stone is a stone.” It isn’t. Cordierite and Biscotto behave like two different tools, and pretending they do the same job is a mistake.
Below is the straight, unromantic breakdown so you can choose properly.
Cordierite Stone — The Workhorse
Cordierite is the default choice for a reason: it’s tough, predictable, and handles a wide temperature range without fuss. At 20 mm thick, it stores enough heat for steady, even cooking across multiple styles—New York, Detroit, pan pizza, focaccia, you name it. It recovers heat quickly, which is why you can cook back-to-back without the floor dropping in performance.
Cordierite excels between 180°C and 450°C. That range covers 95% of home cooking scenarios from slow bakes to fast stone-fired pizzas. Its upper limit is around 450°C; push it beyond that and you begin to overstress the material. It won’t catastrophically fail, but it won’t perform properly either. The balance here is stability over extreme speed—controlled bakes rather than one-shot Neapolitan heat.
In short: Cordierite is your reliable all-rounder. If you want one stone that can do everything, this is it.
Biscotto Clay Stone — The Specialist
If cordierite is the generalist, Biscotto is the specialist. Hand-made in Italy, these stones are designed from the ground up for ultra-high-heat Neapolitan baking. They typically range from 17–20 mm thick, but their composition matters more than the measurement. Biscotto is porous, heat-absorbent, and slower to release energy. That sounds counter-intuitive until you put a 62–65% hydration dough on a 480–500°C floor.
The danger at those temperatures is instant scorch. Biscotto prevents this by moderating the heat transfer: hot enough to puff the cornicione in seconds, gentle enough not to carbonise the base. That’s the trick. No other stone material performs this way at 450°C+.
Ideal range: 320°C to 500°C+. It thrives where cordierite taps out. If your goal is true Neapolitan—60-90 second bakes, blistering leopard spots, soft interior, structured crust—Biscotto is the correct tool.
The downside? It’s more fragile, slower to heat, and absolutely not suitable for greasy foods or pan-style pizzas. It’s purpose-built. Use it incorrectly and you’ll be disappointed; use it correctly and nothing else compares.
| Feature | Cordierite Stone | Biscotto Stone |
|---|---|---|
| Thickness | 20mm | 17-20mm (Handmade in Italy) |
| Best Use Case | Versatile Styles | Neapolitan Pizza |
| Ideal Cooking Range | 180°C to 450°C | 320°C to 500°C |
| Max Temperature | 450°C | 500°C+ |
Which Should You Choose?
With Ziola you don’t need to choose. The Biscotto package includes both stones because most users cook across multiple styles. Cordierite handles the daily workload. Biscotto handles the high-heat, purist sessions. Swapping stones takes seconds and gives you complete control over the cooking profile.
If you primarily cook classic pizza styles, cordierite will outperform. If you’re chasing AVPN-style Neapolitan at 450–500°C, there’s no debate: Biscotto wins.
Both stones extend Ziola’s capability far beyond typical electric ovens. Use each for what it’s built for and you’ll see the difference immediately.
The Biscotto option, you'll receive both Cordierite and Biscotto stones with your Ziola.
