I'm using two slips these days, one with 6-tile(a N.C. kaolin) as it's base and one with a French kaolin. I like them both, one being thicker and paler, the other a thinner, orangier skin. But I need to use a different clay for each because of problems with fit. I hate wasting tests on tiles that I can't make use of, so for years I've been making these 2' - 3" tiles. I have hundreds (if not thousands) of them and there are several 'installations' scattered around LibertyTown. I also showed you the hearth extension in front of my fireplace which is tiled with them a couple of months ago. They also are installed in Paul and Emily's shower. Jason and Lisa's, too. One day I'll figure out a more serious project. It's the great joy and the great dilemma of being a maker...w-a-a--y too many ideas and projects...not nearly enough time. And sometimes it just takes years to find the right place for an idea to blossom.
