 2 Sgraffito Workshops scheduled

This folk art embodies a passion for life with its birds, hearts, tulips and the sense of innocence.
Perspective, proportion and perfection were not a requirement to the Pennsylvania German makers but the joy was!

My Work

I craft one-of-a-kind pottery, inspired by the traditions and techniques of Pennsylvania German potters from the late 1600's to the mid 1800's. My collection includes plates, bowls and ornaments with original designs, some inspired by antique redware and custom pottery made just for you.

The decorating technique for many of my pieces uses the ancient art of Sgraffito, utilized by the Pennsylvania German potters - scratching through a layer of white earthenware slip to the red clay beneath to create original and traditional Pennsylvania German designs.   I make my pieces entirely by hand from red earthenware clay flattened with a rolling pin, then shaped using wood or clay molds. These pieces, which I decorate one at a time, are known as Redware.

I am a Master Artisan of the Pennsylvania Guild of Craftsmen, and the President of its Lehigh Valley Chapter.  I have been included in the 2016 Directory of Traditional American Crafts presented by Early American Life magazine.  My artwork is found at shows and shops located near Allentown, Pennsylvania.

 Sgraffito ware (also spelled sgrafitto) - Slip (liquid clay) of a different color is applied to the red earthenware clay, then the slip is scratched away to reveal the clay beneath to create the design.
