This is a traditional bowl by Lorriane Williams.  It is a round bowl and has a cloud design around the rim.  Below is a river pattern and near the base is a mountain design.  The bowl 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.   It is signed on the bottom in the clay, “LW”.  Lorraine has won numerous awards for her pottery and been featured in books such as “A Legacy of Generations”.
