Plastics In The School And Home Workshop | by Andrew Jules Lockrey



This book aims to introduce to hobbyists and students, a new material which in my humble opinion offers greater rewards in beauty and usefulness for the time and money spent on it than any other crafts material, and second, to eliminate a great deal of the mystery surrounding the methods of working this material by reducing to a school and home workshop basis the actual professional processes and methods used by the big manufacturers.
