Because I am US based and most of the Metal Clay Now Facebook (for which this document was originally created) users are US based, for consistency all the temps are in fahrenheit. Personaly I would very much rather use metric.

All firing temperature and hold times are for reference only. You must always test the clay you are using in your own kiln before firing any finished pieces.

Calculation for enlargement by Margaret Schindel

Here's how to calculate how much to enlarge your design based on the shrinkage of your chosen clay, so that your piece shrinks to the desired finished size after firing.

Step 1: Subtract the shrinkage percentage of your clay from 100%. For example, if you use a clay formula that shrinks 9%, that would be 91% (100%-9%).
Step 2: Divide 100 by by that number to get your enlargement factor. For example, for a clay with 9% shrinkage, you would enlarge your design by 110% in the clay stage (100/91 = 110).

Another example: if your clay shrinks 15%, you would make your piece 118% larger than your desired finished size (100-15=85; 100/85=118).
