U/M and Assembly Items Question

I make an item, slip, from raw ingredients we buy in 50, 10 and 5 lb bags or gallon containers. These ingredients are used in 1/2 oz, 1 oz or 50 lb qty to make a batch. Each batch is 160 cups. Cups is how we use the slip to make greenware. Can anyone help with a detailed step by step for the U/M for raw ingredients and how to use those to make a batch of slip which gets used by the cup, please? It will help me keep the rest of my hair. LOL  Thank you in advance!
