[@Compastian]

Thank you so much for this video. I'm better understanding your book by seeing this chart!!

[@SunAngelD]

Wow, I value ALL THESE LESSONS you provide....FREE!

[@tyrondaniels9293]

John, thank you for schooling us on the tube. basics are always the most vital.

[@claymazingartworks5682]

I received a D grade in High School Chemistry 😱 As a MERRY CHRISTMAS to ME. I bought your book 👍. These Courses couldn't have come at a better time. I am not only chemistry deficient, I can't do a hair braid, Despite the fact I've been a stylist for 50 years 🤣..Thank you so much.. I'm so thrilled you're back in the saddle and healing 🥰

[@rondacorkhill1654]

Thankful I have your book. Also thankful you have created these videos. Sometimes it's just easier to have a verbal walk through. Hope you are weathering the pandemic well.

[@homs.1765]

You are a wonderful teacher! Thank you so much for your generosity!

Thanks John!! Giving us these videos help so much. I can read the same line (in your book) over and over and still not be able to fully understand what is being said, adding these videos help fill the gap or block that seems to form in my head while reading. It's amazing how you can describe the same this in the videos and I can actually understand what you are saying. Thanks again and keep u the good work. My builder finally broke ground on my new home in SC. Once I get settled I am sure I will be able to sign up for your classes. I could spend days going over test tiles alone. Thanks

Hi David how can I get this book?

[@yesimsengil921]

Many thanks for explaning the R20:RO ratio. I was wondering about it. I searched some books and open sources but couldn't find it till now. Now I start to understand what is happening little by little.

[@chardee1694]

I laughed out loud at " I'm by myself as usual - no friends" lol.. funny stuff

[@rondacorkhill1654]

I did as well.

[@Neldidellavittoria]

[@theferalhousewife-knitting5145]

Thank you for doing these.

[@deepashtray5605]

Digitalfire rocks! I've gotten so much good information from it.

[@liatbenadiva5971]

Thank you, thats great order in materiels❤

[@SunAngelD]

✌ THANKS SOOOO MUCH. I appreciate your lesson and time.

[@drelfenbein]

Awesome explainer, thanks for putting all this content out for free! I am currently assembling plenty of your recipes from the high fire book, yet i fire in oxidation. I thought to fire to 1274 in my electric kiln and hold for 20 mins with a 84°C/h climb before. Would that be too low for many basic cone 10 recipes ?

[@johnbrittpottery]

That should work fine. Just put in cones so you know. I often work at that temperature...kaki, oil spots, yellow, oribe, etc.

[@drelfenbein]

@@johnbrittpottery cool! thank you :) I decided to try out about 10 glaze tests first and see how the firing went. I can check the usb record afterwards and then put int the remaining 19 testers! Can't wait to see the results.

[@Musiklovergurl]

Great John! Thank you!

[@____Ann____]

Thank you for explaining so well.

[@sumananindo]

Sir john, hello from India. I have just started to learn about glazes. I am using cone 6 firing and looking for a better understanding of the mid fire range. Which book are you referring to in the videos? Is it the mid range glazes guide book written by you!

[@johnbrittpottery]

Yes in both books. Page 21-29 or so.

[@armorlebihan9340]

Thankk you so much, very very very usefull.

[@shyamarvadia2542]

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

[@johnbrittpottery]

@shyamarvadia2542 t Both..The Complete Guide to Mid-Range Glazes...and The Complete Guide to High Fire Glazes.

[@shanikayeomans2488]

Thank you very much indeed 😊

[@hojoinhisarcher]

[@AnkurKumar-kk3tc]

[@johnbrittpottery]

Is it a book title or just something on line?

[@mattmurray778]

This is great thank you so much

[@rulasalsa]

thanks a lot, a lot to learn

[@renugupta3017]

Vry nice info.. i have ur book also

[@michaeldausmann6066]

Thanks John, heaps of good info.. tomato red is somewhat toxic!

[@johnbrittpottery]

Didn't think I said that....complicated because of silica and alumina...etc.

[@johnbrittpottery]

Guess I am saying individual oxides can be listed as toxic but the glaze can be fine.

[@omanihooper]

Which book of yours

[@johnbrittpottery]

Midrange

[@omanihooper]

Thanks

[@thomasleoncomedy]

Hey John-- been going through these tutorials past couple days and they are fascinating. I'm exploring crackle glazes and you've brought up previously that crackle isn't good for functional ware. I'm seeing some potters (www.floriangadsby.com/gallery/) using crackle glazes in their functional ware-- bowls, plates, mugs, etc. Is there any instance in which crazing could be considered food safe/functional, or is this an error on their part for selling these pieces as functional?

[@edelgyn2699]

Shame you didn't get an response to your questions. I hope by now your experience had guided you towards why there appears to be a conflict in what you were told as a beginner and what you see established potters practice.
