This lecture and information for understanding glaze chemistry is absolute gold! Thank you so much!

[t.l.c.]

Thanks for this. Been a blacksmith and knife maker for over a decade and am unable to continue so am going to start pottery. These videos make the learning curve so much shorter. Much appreciated.

49:00 There may be a substantial oversight, that description is for Sodium Bentonite, but there is also Calcium Bentonite which is has very different properties. some of those recipes that call for high amounts of bentonite are probably using Ca Bentonite. They have the same base chemical backbone structure but one has Sodium stuffed between the layers which allows very strong water absorption and the other is stuffed with Ca giving it a much more stable physical structure. Sodium bentonite is used for many industrial applications due to its gelling and expansive qualities.

Incredible teaching!! I have been reading and watching videos on making glazes for months now and this was the clearest and most usable instruction I have found.

[parinaztayyebi]

I can't thank you enough for making this great series! It's super clear and helpful!I never thought I could really understand the chemistry behind glazes🙏🏻🙏🏻

[pegviqi]

This was the best video I have watched about glaze chemistry. Thank you so much.

[katiez]

I majored in chemistry and I want to learn about ancient pottery. I’m so glad I found your site. Refreshing.

[shanikayeomans]

Watching glaze chapters second time and picking up more. Great video for understanding glazes.

[franceslandfear]

Gold. These videos are answering so many of my questions. Even some I didn’t know I had. And confirming a few of my suspicions and intuition. Thanks for such thoughtful classes and sharing them!

[safyahmed]

I can't thank you enough; You are a great teacher, thank you.

[baumes]

Wow such knowledge shared for free !!!! Thank you so much

[rafaelm]

Just starting to get into pottery, and I find these lectures very instructive.

[aaronbowden]

Wow, Amazing- I needed this Glaze chemistry information! Thank you, thank you. I'm feeling less fear about starting to make my own glazes.

[matospma]

Amazing lecture! Thank you for publishing

[rondacorkhill]

Now that I have my own glaze ingredients, this was an awesome refresher. I recently saw a recipe for colminite.

[bluebelllg]

Thank you for this video. The explanation is so good.

[imkejassmann]

Wow, this was exactly what I needed in my learning process! It was not also interesting and informative but a real joy and fun to listen to the teacher, even for me as a german ceramist. Thanks so much for these videos! They are highly appreciated!

[NeffTattoo]

This is amazing! I learned more about glaze chemistry than when I earned my Ceramics
