View Full Bio

Bob Leatherbarrow established Leatherbarrow Glass Studio in 1988 and has created original kilnformed glass ever since. Known for his innovative styles, techniques, and designs, Bob has taken an experimental approach to developing unique textures and colour palettes using glass powders. His glass bowls and sculptures explore the subtle hues and delicate beauty of naturally occurring textures and encourage the viewer to ponder their origin. In 2008 Bob moved to Salt Spring Island, British Columbia, where he continues to make glass art and write e-books on his signature techniques. Bob has also been a popular instructor on both the national and international kilnformed glass scenes and has recently shared many of his techniques through the comprehensive AAE video class program.

Pebble, Oriented, and Colour-Filled-Veins Textures

by Bob Leatherbarrow

This technical guide is a follow-up to our popular Introduction to Kilnformed Glass Powders: Basic Crackle Texture, Micro and Backed Wafers (2015). Like the introductory book, it is based on many workshops taught over a number of years. Using the basic crackle technique as a starting point, our new book details the following techniques and topics:

  • pebble textures
  • colour-filled-veins textures
  • tack-fused controlled-orientation textures
  • organic controlled-orientation textures
  • encased textures

If you are interested in working with kilnformed glass powders and expanding your repertoire of textural techniques made with powders, this is your book! 


  • 113 pages of clearly documented step-by-step instructions for the 5 included textures
  • 115 quality images to accompany the instructions
  • thorough explanations of important details related to working with powders, e.g., how variations in the basic crackle technique can control textural outcomes, using powder to enhance design, using chemical reactions to create fine lines
  • firing schedules and the logic behind their development (in both °Celsius and °Fahrenheit)
  • guidelines for finishing and slumping projects into gallery quality pieces
  • a gallery of finished artwork, with accompanying stories, to illustrate a range of applications for the techniques described in this book


  • Knowing how to make the basic crackle texture described in Introduction to Kilnformed Glass Powders (Book 1) is essential for learning the techniques in Intermediate Kilnformed Glass Powders (Book 2). There is no review of basic crackle in Book 2.
