So, so good.

I am not a potter and I don’t know anything about clay and/or glaze…until now. Love the show! It’s educational, informative, and for all levels.

Best Co-worker’s EVER!

Kathy, Matt & Rose have become my long distance co-workers. As a studio ceramicist, I work alone with the exception of my fur-child/dust mop little terrier. Don’t worry- I DO mop. It is peaceful to have my studio solitude but SOMETIMES it’s just plain lonely. I have binge watched seasons of shows during production stages where I don’t really have to look at what I’m doing (pinching pots is something I do by feel, for example). I absolutely love the wisdom and enthusiasm that this trio bring to the production stages where I HAVE to look at my task. Even on days when the topic doesn’t SEEM like something pertinent to MY practice, I always learn something new or find a new ceramist to follow or resource to google.
For clay geeks, this show can be as riveting as a murder mystery podcast as they discuss mysterious studio happenings in a “who done it” investigative style. Mysteries like “Why did my glaze do that thing that I HATE” or “how do I get away with NOT following the golden rules of studio ceramics?” These guys will always show up on time and they never fail to remind me of how much I DO know and of things I didn’t know that I needed to.
Obviously, I love this show and I’m grateful to have these people as my on-call co-workers for those days when working alone feels restless and my home studio seems like a hermitage. Thanks you guys for your commitment to research and levity, particularly when discussing technical topics that tend to make a creative’s eyes glaze over (pun intended). This show is my FAV!

The Best!

I love this podcast from my favorite teachers Matt & Rose Katz. Fun and informative.
