Excited to share this week's podcast release from The Maker's Playbook. During Episode 205: Succeeding by Specializing with Matt Katz, Matt and Rebecca discuss CMW's origin story and how lucky we are to have our community!
We celebrated our 5th Anniversary on November 1st! We had a great time showing everyone around our new studio and answering questions! If you missed it, you can view our Facebook Live Event below!
We are Americans, that is true; but let's be honest. Fahrenheit is some made up nonsense. Celsius is the temperature of the world and science, which is why we use it. But we do know that a lot of you out there still use F. So we put this together so you can compare and contrast temperature. For more on cones, of course you can go to the source Orton. Or check out our video on cones.
CMW student Shay Cohen's work is highlighted in a recent issue of Bonsai Focus https://www.bonsaifocus.com .
One of our students, Brenna Dee McBroom has an article in the Sept/Oct 2021 issue of Pottery Making Illustrated called: Developing a Microcrystalline Glaze Palette. Read it here!
Our new podcast just launched and we are so tickled with the name and the podcast network. So join us over on the Brickyard Network and have a listen. The podcast is listener submitted questions that we answer with our dear friend and host Kathy King! So send us a voice memo at firstname.lastname@example.org. We will also be posting supplemental info on this page so be sure to come back often.
Bisque Temperature and Glaze Absorption
This is a test showing how different bisque temperature with water content can affect glaze application.
Listen to our next podcast on the Brickyard Network.
When we talk about converting a glaze from Cone 10 to cone 6, we need to have a precise understanding of our chemistry.
First we need to understand what materials we are using to get the temperature down. The majority of the time, the best option is Boron. We find this material in frits, but also in naturally occurring materials such as Gerstley Borate, and Colemanite.
How much Boron is also important. In this image we see 0.03 increases in Boron, via UMF. In our research (See NCECA Journal 2012) we have found that roughly 0.15 Boron is an ideal level for a ^6 Glaze. We have to be careful though as too much boron in this case kills the color. The color peaks at 0.19 and then as the glaze becomes increasingly overfired, the color begins to fade and turn brown.
If you want to learn more about how your glazes really work, join us for our next Session or Understanding Glazes, begging July 1st! Our in-depth study of how and why glazes work and how to make the most of them. It is the same course we teach as schools such at Alfred University, The Rhode Island School of Design and Harvard University! Open to makers all over the world, of all experience levels! All you need is an internet connection!
Also, We're having a follower drive and we need your help! We need to get to 10,000 Instagram followers so we're having a contest to help us get there.
To enter our contest, we need you to tag a friend in CMW posts made between now and July 1st. Then, make sure your friend follows us too.
If you just got tagged, you can also join again, by tagging new friends!
I've had a few conversions recently about glaze durability. Here is my article that I published in the 2016 NCECA journal on that subject.
I looked into the the question of why glazes are durable or not and found that we are able to correlate the overall durability of a glaze to its underlying chemistry.
We are also able to put to rest the "Lemon Test" which we found was a test of little value.
