A book written by Alfred Professor Val Cushing (1931-2013). The book is a compendium of topics, from technique, to clay and glaze chemistry, as well as containing a collection of formulas.
Famously, the book was never formally published. It is a simple volume that is only available from local stores in Alfred, New York. The Rogue Carrot (formerly Kinfolk) a local grocery, will sell and ship the book to you.
