This is a large bowl by Lorriane Williams.  It is a wide shape with a sharp shoulder.  The piece is incised with two Yei masks on either side.  There is a connecting rug pattern.  The designs are further highlighted with additional clay slips.  It has been traditionally fired.  After the piece is fired it is covered in pine pitch, which is typical of all traditional Navajo pottery harkening back to when it was utilitarian.  Lorraine has won numerous awards for her pottery and been featured in books such as “A Legacy of Generations”.
