Glass in the bottom of a pizza oven may seem like an unusual choice, but there are actually several reasons why it can be beneficial. Here are some reasons why glass can be used in the bottom of a pizza oven:
Insulation: Glass bottles can provide insulation against heat, which can help to maintain a consistent temperature inside the oven. This can be especially important when cooking pizzas, as uneven temperatures can result in undercooked or burnt crusts.
Reuse of materials: By using glass bottles in the oven, it’s possible to reuse materials that might otherwise go to waste. For example, in the case of the oven mentioned in the question, the earth and bottles from the original oven were reused in the new one. This can be a sustainable and eco-friendly way to build an oven.
Cheaper than other materials: Glass bottles can be a cost-effective alternative to other materials that might be used in pizza ovens, such as firebricks. This can be especially appealing for those who want to build an oven on a budget.
Aesthetic appeal: Depending on the design of the oven, glass bottles can add a unique and attractive decorative element. For example, if the oven has an open front, the bottles might create a colourful and eye-catching pattern.
While glass might not be the most conventional choice for a pizza oven, it can offer several benefits when used properly. Whether you’re building your own oven or simply curious about the various materials that can be used, it’s worth exploring the possibilities of this unexpected material.
