This is because glass packaging is soda lime glass. That means it is made from sand, soda ash and limestone. Other kinds of glass can contain a variety of other ingredients, which could cause problems in a glass container melting furnace. Laboratory glass can be particularly risky, as it may be either borasilica or soda lime. Any chemicals remaining in the lab glass may also be a concern.
Some brokers do handle different types of glass, though often only in bulk quantities.
Bulk quantities are unlikely to be found in a household setting. If you have a substantial amount of non-container glass, your best bet is to consult local recyclers. Segregated by brand b. Copyright 1990-2001 Louisiana Department of Environmental Quality. All Rights Reserved.
