I was given a couple of glaze recipes from a potter in England. This person mixes glazes using pounds/ounces. I converted from ounces to grams. Should this make a difference in mixing the glazes? Totaled up, it comes to an odd number like 2501.84. I don't want to mix that large of a batch initially, so for testing purposes, I divided by 10. so I would be working with a batch of 250.18. Am I on the right track with this?? Thanks for your help.
