[Clay Recipe in Parts? Weight or Volume?]

That makes sense, thank you.

[Clay Recipe in Parts? Weight or Volume?]

Thank you Diesel...I have found several different recipes with various formulations.  Some by weight, parts, percentage, and one that was listed as proportions.  As a newbie it was a little confusing, but the one listed on The Claybucket site seemed reasonable, especially if a college is using the recipe as their primary clay and all components were readily available at my local ceramics shop.  I just did not want to mess it up and figured I would ask some folks who have been doing it for a while.

Thank both of you for responding - looking to make highfire claybody.  I full understand the accuracy of weight over volume, but with the recipe as listed it would be a wildly different formula on weight versus volume, that is why I questioned it.  I was just not sure when I see recipes listed as "parts" if it was weight or volume in general unless otherwise specified.  Again - thanks for the responses.  New to the art and trying to learn.

[Clay Recipe in Parts? Weight or Volume?]

New to pottery and currently exploring clay recipes.  I found a stoneware recipe "IUS Shop Stoneware"  and the recipe is in parts.  Probably a silly question, but I am new and do not understand if these parts are by volume or weight.  Can anyone explain how clay recipes in "Parts" are actually measured out?
