What effect do different slash patterns have on bread oven spring?
Slashes in bread loaves are designed to promote oven spring but there are many different patterns. Some running the length of a loaf, some in a checkered pattern. I've been told this is to promote oven spring in different directions.
What patterns lend themselves to spring in what directions? For example, I know a checkered pattern, promotes expansion upward.
Best Answer
Slashing the skin of a loaf creates a weak area. When the oven spring occurs the dough will expand through that weak spot. Expansion will be limited in the stronger, unslashed areas.
Conceptually this is fairly simple. Leave the skin unslashed in the direction you don't want the bread to expand. In the case of a checker slash on the surface of a boule- the edge stays stronger than the entire center so the expansion is forced upwards.
In practice, with different loaves, it may be difficult to predict exactly how the physics will occur. You can start with traditional slash patterns that you see on professionally produced bread.
For example, on long loaves, such as baguettes, the slashes are short, at a slight angle to the length, and overlapping to promote lengthening of the loaf. Whereas on wider, football-shaped loaves the slash may run parallel to the loaf to widen it a little.
As a demonstration I baked two loaves this weekend. They were identically formed as small football-shaped loaves (batards). One I slashed at an angle, the other parallel with the length.

Quick Answer about "What effect do different slash patterns have on bread oven spring?"
The different slashing patterns restrain or encourage the oven spring upward.What factors affect oven spring?
There are many factors that influence the degree and quality of the oven spring when baking bread: overall dough quality, the amount of yeast in the dough, the degree of fermentation (it should not be under fermented or over fermented), and oven temperature.Does scoring affect oven spring?
The way you score your bread will have an affect on which way the loaf will 'spring'. The purpose of scoring, is to produce weak areas on the surface of the loaf, which directs where the bread expands during its oven spring.Why are slashes cut in the tops of bread?
Scoring is slashing the dough with a blade or a sharp knife to allow it to expand during baking. The purpose is primarily to control the direction in which the bread will expand during \u201coven spring.\u201d Easier said then done!What is the purpose of slashing in baking?
Scoring is the technique term for slashing bread dough before baking with a sharp knife or lame. Slashing creates weak spots in the bread's crust, allowing for expansion instead of burst seams.5 WAYS TO GET A BETTER OVEN SPRING | SOURDOUGH BREAD TIPS

Answer 2
Slashes allow the carbon dioxide released from the yeast to escape at specific points in the bread, yielding an even shaped loaf. They are used to stop the spring from tearing the bread randomly, which could create burned areas on the surface where it split or cracked. There is no specific pattern that works better than others, and they all tend to promote expansion upward and outward.
