The fired linear shrinkage is illustrated by the image below. Two essential parameters are needed to calculate fired linear shrinkage: dried length (DL) and fired length (FL).
The formula for calculating fired linear shrinkage:
FLS = 100(DLÂ – FL/DL)
Where:
FLS = Fired Linear Shrinkage
DLÂ = Dried Length
FLÂ = Fired Length
Given an example;
Find the fired linear shrinkage when the dried length is 32 and the fired length is 12.
This implies that;
DL = Dried Length = 32
FL = Fired Length = 12
FLS = 100(DLÂ – FL/DL)
FLS = 100((32 – 12)/32)
So, FLS = 100(20/32)
FLS = 100(0.625)
FLS = 62.5
Therefore, the fired linear shrinkage is 62.5%.
