Bare oven floor
Direct baking on the oven's own floor, only viable in commercial deck ovens or domestic ovens explicitly designed to allow it.
Material and heat transfer
The oven's own stone, brick, or metal deck
Varies entirely by oven construction; commercial deck ovens are purpose-built for this, domestic ovens rarely are
Preheat: Only usable directly in ovens whose floor is a bare, oven-safe deck (most domestic ovens are not, due to heating elements or non-stick coatings)
Crust effect
Where usable, gives the most direct possible heat transfer to the base
Care
Only attempt in ovens explicitly designed for it
- Most domestic ovens are not safe to place dough directly on their floor
- Requires an oven purpose-built with a bare deck
