Try contacting The Society of Glass and Ceramic Decorators (SGCD). It is "a worldwide organization that provides decorating professionals with a competitive edge in business by providing opportunities for networking to learn about new decorating technologies and techniques." http://www.sgcd.org/ 

Their members should have the kind of technical expertise you require. 

Please let me know if I can provide further information.
