Very Rare Large Cobalt Blue MFC Slag out of the famous Weisenbarger MFC portfolio. It displays a fantastic swirly “9” pattern and tail that disappears towards the deep blue glass with the classic “cut line.” Reportedly, this is about the largest Blue Slags MFC recorded making. Each color type had a different largest known size. These huge MFC slags seldom come up in top condition, and especially in the largest sizes for it’s color class!
