Can You Put Glass In A Pizza Oven? Is It Possible?

Who doesn’t like a good pizza, eh? That thin crust, with tangy sauce, delicious cheese, and meat or veggies of your choice? A match made in heaven!

But as much as the dough and other elements matter in a pizza, the oven is also the star here. And any pizza enthusiast will swear by it. Without the perfect oven, you cannot get that crispy crust. And pizza is nothing without a crust. 

The main thing about the pizza oven, brick or metal, is to insulate the heat. And what better insulator than a glass, right? But can you put glass in a pizza oven?

Well, traditional pizza oven users will deny the claim of using glass in a pizza oven. The reasons can go from the glass breaking to not bringing in the earthy flavor in the crust. But whatever the reason is, you should not put regular glass in a pizza oven. Instead, go metal or use ceramic glass.

We are going to talk more about it and you will have an idea why in the end.

Why You Cannot Put Glass In A Pizza Oven

Traditional pizza ovens are built of bricks, stones, and cement and can be powered by wood, gas, or electricity. Wood and gas are more common out of the three. And you can buy stove-top pizza ovens too, which are more modern.

There would be a pizza stone where you place your pizza in the oven. And a metal door in the front. The glass is placed between the outer boundary and the inside of the pizza oven dome. This allows the heat to stay inside more, creating insulation. You will find that people are using old glass bottles, and broken shards of glass on both the dome and also on the bottom of the oven. 

But regular glass has a melting point of 1500 degrees. Which a pizza oven can’t reach, but with constant use and tear, it will develop cracks and will break. 

This is why regular glass is not used in the pizza oven, rather ceramic glass is used instead. The way ceramic glass is manufactured makes it withstands over 1800 degrees. A pizza oven operates around 500-700 degrees. And also, the chemical compound of ceramic glass also works like a pizza stone. With soda ash, sand, and lime, you get the perfect insulation and also, longevity. 

So instead of putting regular glass in your pizza oven, ceramic glass would be a better option. Metals like iron will also work. But the best thing would be going authentic with ceramic glass.
