The "pottery place", as it is affectionately referred to by the McGonagills, is an add-on to a horse stable/barn now converted into a wood-working shop and pottery studio (see thumbnail).  

Inside, there are two different wheels and three kilns (with computerized controllers) which are used in a variety of ways.  

The stoneware and porcelain clays are kept in storage bags in an old chest freezer until ready for use.  The shelving is lined with greenware and bisque-fired pieces in various stages of readiness.
