As a Museum devoted to ceramics, at the Gardiner we believe nothing is more wonderful, natural, or beautiful than clay. Saying “Clay is (so) gay”, is a statement of support for the gay community. Clay is wonderful, so is gay.
We’re also making a statement about the phrase “so gay” with the parenthetical addition of the word “(so)”. Some people feel this phrase has a negative connotation, and we’re certainly aware some use it that way. That’s why the Gardiner is taking just the opposite approach – we are proud to say clay is gay and, for that matter, so gay.
