Very informative ty 😊!!!!

Thanks, John. This was helpful.

Thank you so much for this! I was given 2 quarts of human cremains and asked to use them all (!) and make ceramic sculptures, small bowls, stones, etc. for the cemetary. I found and tried this recipe and the clay was very short and crumbly. I added Bentonite, some ball clay, and more water and wedged it for a long time until I finally had a ball that I was able to pinch into a small bowl. It is still drying. Should I bisque per usual with this? I am trying to make bone ash glaze to help me use up the bone ash but I haven;t found a suitable recipe. Do you have one? I need one that uses 15% or more bone ash. I tried a wood ash glaze recipe but it fired rough and bubbly. Any thouhgts and pointers are much appreciated.

I bought your book, but it never came.

Is the plate food safe?

Another awesome video ty 💯!!!!

OMG this is amazing, this is such a great resumé. I'm amazed that I do understand it at one glance. This is frantastic and sooooo good to review to better undertand everything in glazes. Thank you very much for your generosity. I'm a new potter (three years only) and I'll definitely have a look at this video every now and then to remind me the main points. Hello from Belgium.

Ty so much for this video!!!!!!!!!

Your so inspirational I thank you sir:)!!! This is awesome 👍😎

This video is awesome 👍😎 Please make us some more,your very knowledgeable and very helpful!

Wowww

Merci Beaucoup John je vous suis depuis longtemps et j espère pouvoir acheter votre nouveau livre sur les gouttes d huile tous vos résultats sont magnifiques

We're not worthy

Thanks John your so awesome 👍😎👍

I don't cut plates of shiny bats ,they just pop of at the right time for turning

Wow this video was super interesting and helpful! Been reading your book about mid fire glazes and am learning so much!! Thank you for sharing all your experience with us it really is so helpful Lucia

Basically he's throwing in a European style...lighting and composition is ok...throwing is exceptional!

I can’t find the video of the results

Which book does of his does he refer to here? Where to read more about these oxides?

Pottery is a great art but all the calculations makes my head swim,

Oh John, Thank you so much for this incredible gift. Your generosity with sharing your knowledge is so appreciated. Heading over to purchase myself your PDF. Much obliged.

John how to make mold thermoforming pleas

So cool! I love you dishes! Thank you for sharing, I have you book and love it!

Excellent video. I always learn when I watch your channel. Thanks for posting!

John, hope you are doing well and did not suffer damage from hurricane Helene.

Is neph sye also feldspar please?

Hello John! Just thought to let you know that you're raising a great ceramist here virtually in Nigeria. I look forward to seeing you someday very soon🎉🎉❤❤

So clever!

Looks like someone was doing a spitting contest all that foam.

It would be interesting to measure the melting point temperature for each but I don't know how to do the on something that hot. For organics, we did it using a glass capillary tube attached to a mercury thermometer then heated it with a torch until it melted the measured the temperature. I imaging the capillary tube would work and a MAPP gas torch would get hot enough but a mercury thermometer won't go that high. Maybe you could do the same thing but use a Pyrometer rather then a thermometer. It would also be cool if you could measure the melt viscosity for each. I am very much a numbers guy.

Thanks John. Founds like a fun science experiment. Unfortunately I am a full time engineer, part time professor, and a "when I can find the time" potter. 😉

Hi John , newbie here… I’m on Glazy and the recipes don’t mentioned the amount of h20 to use …. I’m assuming it’s 100 g ? To make a test batch .. and distilled water ?.. just bought your book COMPLETE GUIDE TO MID-RANGE, fantastic !

Thank you so much. I really appreciate you for posting these videos. They are very helpful 🙏

Hi John , As a beginner what glaze with you recommend for a cone 6

excelente para los que estamos aprendiendo , muchas gracias!!!

I am always amazed and grateful that you share your knowledge! your online classes are amazing. Greetings from Guayaquil, Ecuador!

Wow. What an encyclopedia of knowledge. I now have a more full appreciation for the spectrums of glazes that are available for different pieces. Than you John for synthesizing the eons of experience into this logical format.

Hi John, I'm the glaze maker at a community studio and I've worked with GB in our glazes for years, until we switched to Laguna's gb blend, which worked fine, then to Gillespie (carnage) and back to GB blend (which was different the second time we bought it-acted more similar to Gillespie than before- my hypothesis is that Laguna is cutting the last of their GB with Gillespie in larger percentages of the latter until GB is gone.) Our glazes crawled with Gillespie ESPECIALLY when a Gillespie containing glaze was the first layer. Hypothesis: the ulexite is doing a crazy thing (reference digitalfire for photo) around 1400+ and knocking off the glaze layer above. Very slow firing (slower than kiln presets) fixed the crawling issues for glazes applied singularly, but NOT when layered. Not great in a community studio where people love to overlap, so I've had to replace many glazes to avoid gb (difficult). The only glaze that seems to behave, even with overlapping glaze, is, oddly PV base. Despite the large amount of gb. Must have to do with the large amount of clay in there too/the melt. This has been a summary of my twilight zone for the past several months, hope it helps. Julie Harbers

Thanks John! I’m wondering if the GB substitutes last longer in the glaze bucket. It’s probably too soon to know. Great video!

What cone do you fire to for bisque?

Thanks for sharing John !

This is still one of the best showcases of how(and why) to make a glaze. This is much easier to understand than looking at all the umf/stull charts, limit formulas etc. After watching this lesson those charts and formulas will actually become useful, this is like the missing knowledge piece for newbies in glaze-making. Thank you John!

Legendary. Thank you. But I wonder, if quartz acts as a flux in glazes, why is it a Filler in Clay recipes? With a locally dug low fire terracotta clay that melts at about cone 06, if I add quite a bit of beach sand (containing silica and some calcium) it extends out to around Cone 4 or 5. Making it more refractory. But if I add it to a Cone 10 body the melting temp comes down to a Cone 5 or 6. I find that curious. I am rolling with it but find it odd. SiO2 itself melts at 1670˚C so I would think it would drive the vitrification temp upward in every case.

Did you announce this somewhere that I need to sign up to follow?

Thank you

Great video! Many thanks. I'm looking forward to watch a video with information about soda ash wash over shino in an electric kiln.
