That makes sense, thank you.

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.

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?
