Usage Variations & FAQs
Q: Mayco Stoneware Dry-Mix Glazes don't have to be sieved - why?
A: Our manufacturing process includes ball milling to very precise particles sizes. All you need to do to use our dry-mix glazes is add water, slake, stir and DIP. You'll love the sheeting action when dipping and be pleased to find that our dry-mix glazes will not settle out in your storage bucket.
Q: Can Mayco Stoneware Glazes be fired to cone 10?
A: Yes the can. Some will change significantly, some not much. Best we can do is provide this visual gallery and let you see what each glaze can do at cone 10 reduction: Cone 10 reduction results.
