The American Institute for Conservation has an extensive website that will help you find glass conservators: 

Davison is the basic resource for glass conservation. I have added a list of other books on this subject: 

Davison, Sandra. Conservation and restoration of glass / Sandra Davison. 2nd ed. Oxford ; Boston : Butterworth-Heinemann, 2003. xii, 380 p., [4] p. of plates. 
Previous ed. published as: Conservation of glass / Roy Newton. 1989. 
Includes bibliographical references (p. 349-365) and index. 
NK5104.5 .N56 2003 

If you wish to obtain copies of any of these items, please contact your local library. The Rakow Research Library is a member of the Online Computer Library Center (OCLC); your library can contact us through OCLC or they may mail an Interlibrary Loan form to us. You may request up to five items at a time. We send photocopies of articles and microfiche copies of our books (if they have been microfilmed) through Interlibrary Loan for four weeks use. 

I suggest your contact our conservator, Stephen Koob, for additional advice:
