“I am listening to your lecture in the car through traffic and it’s a different experience now that I understand what you are talking about and actually experienced it myself.”

“One of the most important step I took in my ceramicist life is to follow 2 workshops from @ceramicmaterialsworkshop and learn about what really a glaze is.
I have been working on it since October 2022 and it has been so amazingly interesting, challenging, beautiful, rewarding and exciting.
I am of course only at the beginning of an endless research, but I feel confident about what we can offer in the studio, to the people who order from us and I can wake up one morning, have an idea of a glaze and make it…
It is the best thing I have invested in and I am thanking a million time @studioluma_ceramics
who introduced me to that course and who sadly and tragically passed away last year in the middle of her own glaze research. She is deeply missed.
Thank you also to Matt and Rose for the life changing opportunity with your wonderful workshops @ceramicmaterialsworkshop
It’s just the beginning 🥰” ~Seline – CMW Student

“Thomas here, in France. I just finished your Glaze 1 and 2 lecture only courses and just wanted to drop you a message to thank you for your amazing work….7 years ago, I stopped working as a software engineer and started my ceramic journey….I was also really surprised by the amount of myths in the ceramic field.
I was always feeling like there was some magic happening in the kiln and my scientific background was not really happy about that. That’s why I decided to take your online lecture only classes. I wanted to have a more scientific approach on all that. I just wanted to tell you how happy I am that I followed these lectures. I feel like I have a really better understanding of what’s going on in the kiln now.
Thanks a lot for sharing all those elements, in a clear and entertaining way. I really liked that.”

“Thank you Matt & Rose for creating such an outstanding resource. It is incredible the passion you show for imparting and sharing your knowledge and I’m so grateful for all your time, energy and knowledge.
I’m excited to continue to experiment and develop my ceramic practice putting into the practice the testing methods. I’ve still so much to learn but I have a foundation that will serve me well.
It really is hard to put into words how much you impact my learning. THANK YOU.
