A few years ago Bob stopped teaching workshops focussing instead on sharing his knowledge of working with kilnformed glass powders and his signature techniques in a series of e-Books (downloadable PDFs). We have published four e-Books - an introductory book, an intermediate book, a workbook, and a book on firing schedules.
The intermediate book and workbook build on techniques taught in the introductory book - they are not stand-alone. Thus, a person must first purchase and learn the techniques in the introductory book before moving on to the other two books.
The e-Books are available for purchase on this website, through AAE Glass, and through Warm Glass UK.
