The fired linear shrinkage is illustrated by the image below.

To compute for fired linear shrinkage, two essential parameters are needed and these parameters are **Dried Length (D _{L})** and

**Fired Length (F**

_{L}).The formula for calculating fired linear shrinkage:

FLS = 100(^{DL – FL}/_{DL})

Where:

FLS = Fired Linear Shrinkage

D_{L} = Dried Length

F_{L} = 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;

D_{L} = Dried Length = 32

F_{L} = Fired Length = 12

FLS = 100(^{DL – FL}/_{DL})

FLS = 100(^{(32 – 12)}/_{32})

FLS = 100(^{20}/_{32})

FLS = 100(0.625)

FLS = 62.5

Therefore, the **fired linear shrinkage **is **62.5%.**
