Thank you very much for your question. Henry Halem's book, "Glass Notes a Reference for the Glass Artist" states, "The mold is composed of plaster and silica in a 1:1 ratio by volume or by weight".
Attached is a bibliography regarding mold making and casting. 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. Unfortunately, we do not lend videos at this time.
