I can also track my live woodfirings, expenses, sales, and tasks. Goodbye excel, apple notes, notion! This app does it all. Actually one of my favorite tools is the batch calculator for glaze making.. you can actually set the volume of glaze you want, e.g. 4 gallons, perfect for a 5 gallon bucket and it gives you the amount of material and water you need based on your application type :D. Amazing and it’s free to download and well worth the unlimited upgrade. ## Frequently asked questions about Glaze Lab ### What is Glaze Lab's learning methodology?
