You want to start firing your oven slowly (as is the case with all brick ovens) and you can be cooking on your oven in as little as 60 minutes. If you need a pizza in 30 minutes or less, you may need to call Dominos.
It is VERY important that you heat your oven slowly. You never want to jam a bunch of firewood in an oven in hopes that it will heat faster. You want to heat your oven slowly to prevent thermal shock which can crack your oven.
This rule applies to all quality wood-fired ovens… not just a BrickWood Oven.
