Episode notes
In this episode of The Trades Show, host Briana Ottoboni sits down with MaryMar Keenan, ceramicist and founder of MMClay, in her storefront and studio in Hayes Valley, San Francisco.
Their conversation explores MaryMar’s 30-year journey in ceramics — from discovering her love for clay to building one of San Francisco’s most recognized handmade tableware brands. She shares her philosophy on functional art (“a piece isn’t really finished until it’s used”), the evolution of MMClay, and why she believes handmade pottery should be special, but not precious.
MaryMar also reflects on her transformative trip to Japan, the humbling lessons of working with clay, and how she continues to push her creative edges while running a small-batch production studio. You’ll hear about her innovative experiential pottery workshops, full-circle moments with Michelin-star chefs, and honest advice for aspiring potters navigating the balance of art and business.
Whether you’re a potter, a creative entrepreneur, or simply someone who loves handmade craftsmanship, this episode offers inspiration, insight, and a deep look into the artistry behind everyday objects.
The Trades Show is a show about modern craftwork — a conversation series with artisans and a return to what makes us human: the ability to create with our hands.
