Ceramic Theory

Advanced Ceramic Systems and Glass Design

Company Leadership


Joseph Fellows - President

"Ceramics have long been a significant and creative part of my world.  I have benefited greatly by many years of work in advanced ceramic research and development, it having provided a wealth of understanding and experience in ceramic processing.  I believe that for ceramics, if something appears to be impossible, then with effort a solution can be found.  Ceramic Theory, and the work done here, is my way to provide a unique and positive contribution to the world of ceramic development and glass design."

My work today has been greatly benefited through many years of association in the engineering world with so many people who love ceramics and share the vision of how advanced ceramics can help improve our condition, and make the world an even better place.  I do wish to acknowledge a few individuals especially from previous work who should be noted:

Merrill Wilson - Mechanical Engineer Extraordinaire


Thanks for all those good years.

Dr. Charles Lewinsohn - Dr. of the Prestigious and sometimes Infamous Ceramic Heat Exchanger
