Excellent Product and a Great Company
First things first great company and very quick to ship. I make primarily pit fired pottery. I've been looking for a food safe sealer for cups, bowls, and vases. I've found clay coat to be very easy use with excellent results. A little goes a long way. I bought the 4 oz. and after testing on 6 different items fired to different temps. I immediately ordered a large bottle. I can't recommend this product or company enough.
