May I suggest simplifying the equations presented midway? Let's use a definition like this: shrinkage = finalSize/initialSize. Here, shrinkage = 0.92. To make into an 'enlargement factor' just take the reciprocal: 1/0.92 = 1.0870. In summary: designSize/shrinkage = buildSize.
Does the shrinkage rate change within the same clay body depending on the batch? For example, I bought a clay body from Laguna clay and it has a shrinkate rate of 10% +/- 2%. After using the clay, I discovered it has a shrinkage rate of 12%. If I buy a new bag of this same clay body from Laguna, will it always have a 12% shrinkage rate or could the next bag have a 8% shrinkage rate? Thank you so much for all your lovely videos.
Thanks ! I'm a visual person, and the shrink rule works for my brain. Your Mileage May Vary !

The presented formula confused me too. It clearly shrunk by 8%.
yes! our brains work in different ways. It's always good to see a variety of ways, to find what works for you!
Very helpful. Thank you.
glad the information was useful for you, Joanne!
