This Workbook is a collection of spreadsheets pertaining to metal clay. There are sheets for each brand of clay, carbons, firing vessels and kilns.

The workbook is a living document and is meant to be updated and improved upon. Please feel free to add information that is missing and correct information that is incorrect.

There are columns for notes. Any tips on using the material should go there.

The doc is open for all to access and edit. For now it is only open to people who have the link, it is not searchable through the internet, but feel free to share with fellow metal clay artists who may not be using this Facebook page. It is meant for all the metal clay community.

Calculation for enlargement by Margaret Schindel
19
Subtract the shrinkage percentage from 100% (in the case of 20% shrinkage, that would be 80%), then divide 100 by that number to get your enlargement factor (in this case, 100 / 80 = 125).
