There are many convenient and easy-to-access ceramics glossaries on the web, so this post will give you a few. Note: every glossary is directed towards a particular audience--amateur, scholar, scientist, professional ceramist, so it might help to consult more than one. When using a definition from an on-line glossary, be sure to cite the source properly. For more help on citing electronic sources, consult the Writing Centre, or check the following helpful website:

From the drop-down menu, check "Humanities/Documenting Sources/ "MLA List of Work Cited."
