Have you always wanted to know how glazes REALLY work?



Online Glaze Calculation Course!

Understanding our glazes is the most powerful thing we can do to make our work our own.
Yet how many of us really understand how our glazes work?

Ceramic Materials Workshop is here to help.
You can take our world renowned glaze calculation classes online, right now.

Designed for ceramicists of all levels, our Glaze Calculation courses will change your studio FOREVER.

​After years of teaching ceramic materials courses in a traditional classroom lecture, Matt Katz developed and designed the Ceramic Materials Workshop specifically for online educational access. These innovative courses have proved highly successful; student evaluations consistently praised Matt for his knowledge of ceramic materials and their applications and applauded him for his concise and personable presentation of challenging technical content. The online format proved exceptionally conducive to robust group interaction and discussion. I highly recommend these classes.

Ceramic Materials Workshop is a place online to understand and explore how and why our Clay and Glazes work (and don’t work).

Our materials speak for us in the kitchen and gallery, it benefits us to learn about how to speak through our materials. 

Mastering the skills of clay and glaze performance helps every ceramicists, become their best self in the studio. 

Ceramicists at all levels can now learn how Clay and Glazes function, online.
Here at Ceramic Materials Workshop.
About the instructors:  
Rose Katz
Has worked in the tile industry as a clay and glaze engineer for 10 years.
Rose has B.F.A from Alfred in ceramic art and spent many years as an independent artist and production potter.
Rose took her materials expertise to a mid-sized tile company many years ago, where she used her knowledge of ceramic materials and revolutionized the company’s materials and process. Winning awards and developing hundreds of glazes and clays in the process.
Rose’s experiences as a studio potter and tile maker, make her experience and knowledge truly special.
Matt Katz

He is a working ceramic artist with a B.F.A from Alfred and M.F.A. from the University of Colorado-Boulder
He has worked as a Ceramic Engineer and researcher for almost 20 years.
Katz uses his knowledge of Art and Engineering to make ceramic science understandable for people of all experience levels.
Matt is an experienced online educator, who has crafted an online version of material studies, accessible and understandable for everyone.

Online Courses with Matt Katz (a better way to spend your summer!)

The course is
a 5 week, intensive, online class, and it basically the same course that Matt Katz
teaches to Graduate and Undergraduate students at Alfred.
It is

Instructor: Matt Katz is the creator and
instructor for Introduction to Glaze Formulation Online. Matt has taught
ceramic material courses at The School of Art and Design at Alfred
University for over 12 years. He received a BFA from The School of Art
and Design and a MFA from the University of Colorado, Boulder. Matt’s
extensive study at the Inamori School of Engineering and engagement as a
studio artist have enabled him to design a new version of glaze
formulation that combines the intuition of the artist with the science
of the ceramic engineer. Katz strives to make a complex subject
understandable for individuals of all backgrounds and experience levels.

techical tuesday: Glaze Calculation Online from Alfred University.


Have you ever wondered why cone temperatures are seemingly
random? Have you been frustrated by a glaze that you can’t get to stop crazing.
Have you had enough of your clay body slumping?  What is the deal with Cone 6 anyway? Have you ever wanted to
learn about how glazes work? Do you wonder what goes on in our clay bodies when
we fire them? Do you need a refresher in ceramic materials, or just want to
learn some cool things about clays and glazes?
 The New York
State College of Ceramics at Alfred University has a new opportunity for all
ceramicists out there. This December and January we will offer our Glaze
Calculation and Raw Materials course online. The course will be offered during
our Allen Term, which runs the course of our winter break, December 15th
to January 16th. The class is open to everyone around the world who
wants to learn about ceramic materials.  It is a perfect opportunity if you attended a school that
does not offer a materials course, or if you missed the window to take it at
your school.  The course will be
offered for credit for students currently enrolled at other schools. It is also
open to the general public, if you are a lifelong learner. Maybe you are
someone just getting started in ceramics and want to know more about what is
going on when you fire a glaze. It is also perfect for the professional who
wants to develop the glaze they see in their mind, but just can’t seem to get
on their work.
We will explore everything you need to know about ceramic
materials.  The nature of glazes
and clays, the background on raw materials, ceramic chemistry, how colors work,
oxidation and reduction, firing temperatures and schedules, glaze and clay
flaws and failure, special effect glazes, maximizing clay bodies, food safety,
the unity molecular formula. Everything that you need to know to make your
studio the best it can be.
The New York State College of Ceramics at Alfred University
is an internationally renowned school for the study of ceramics. We have a long
history of educators dedicated not just to ceramic art, but the holistic study
of Ceramics. Pioneers such as Daniel Rhodes, Val Cushing and John Gill have
strived to make ceramics a dynamic and exciting art form for over 100 years.
Alfred also has one of the world’s best ceramic engineering programs. Professors
like Dr. Bill Carty, pioneers in the study of ceramic science from the artist’s
Glaze Calculation Online will be taught by Matt Katz,
Alfred’s professor specializing in ceramic materials. Matt has been teaching
Ceramic Materials at Alfred for over 12 years. Originally studying in the
school of art and design, Matt went on to study with Dr. Carty for many years. Matt
has a special perspective of materials from both the artist and engineer’s
point of view.  Matt’s experience
has allowed him to design a new version of glaze calculation that includes the
intrinsic knowledge of the artists with the wisdom of the ceramic scientist.
We hope that you will join us online this winter; it will be
a course you will always appreciate as you continue to strive to make your
studio experience better.
