John.. I'm just new to pottery, your book was the 1st book I lusted for and bought, Im learning so much from your videos and am so thankful that you kindly share your knowledge. Thanks for all you do for the ceramic world... now I'm off to continue binge watching your videos 👍
Apart from all the blues you can get with Co, an interesting colour is pink in the presence of Mg. Happened to me once by chance. I did some brushwork with Co on a that had quite some dolomite, and all the outlines of the brushwork turned bubble-gum pink. As always, thank you very much indeed.
Love your book and so happy to find your videos! thank you!! I use your book to make my glazes. the chemicals below the solid line on the ingredient list means what? They are very small amounts - do you liquify them first and add? thank you!!
Thank you for these videos!! So happy I found them!! I love your book and have revisited it frequently since graduating. I was curious - what do you think about colorant and water oxide washes applied to the exteriors of bisque, then wiped, and covered with glaze in regards to food safety? I have had such a hard time finding an answer to this. It seems many people don’t talk about it.
Hard to say. Depends on the amount. And various oxides move differently through glazes, like copper tries to move to the top and that is why it make black in larger amounts. Probably ok but hard to say unless you know specifics. Just send it in to be tested. I use Brandywine labs in Mass. Will ease your mind. No one can say for sure but testing will tell.
Thank you so much for sharing your knowledge John :) Is it possible to make my own Rutile from mixing Titanium Dioxide and Iron Oxide? What percentage of iron oxide should I mix to the Titanium Dioxide?
Hard to say as rutile is variable...try 3.5 titanium and 1 red iron....also go on the Facebook Group...Exploring Midrange Glazes Together with John Britts book...someone on the will know...great group. Also, John Britt High Fire Glaze Hroup, Ceramic Recipes.
Yes, Black Nickel is Ni2O3 and Green Nickel is NiO but this is a general overview. I also didn't include various valences of Co, Cu, Mn, etc. But thank you for writing!
Hi John. I know you are busy teaching. I love this series so much. Would there come a part 7? I am very curious about 'material families' . If I don't have f.e. Gerstley borate, what other materials are similar to be able to calculate a substitution. Continue the great work. You always explain so well.
@@johnbrittpottery What a mess with this virus. Here all schools are closed for a month. I understand it is necessary but still. Looking forward to a new video!
Hey I am from India. I basically own a Gas tunnel Furnace which is oxidation I think. And i can not get gerstley borate easily and other stuff. Can you please help with some materials substitute. And email address if you can give.
Thank you for being non partisan. I've recently been inundated by individuals from a specific political party and this isn't where I expected that to happen.

Do you have instructions on reclaiming settled glaze . Thank you for your service. Just found your Chanel today . Excellent

Love your book and so happy to find your videos! thank you!! I use your book to make my glazes. the chemicals below the solid line on the ingredient list means what? They are very small amounts - do you liquify them first and add? thank you!!
Below the line are colorants, opacifier and suspenders. Just add as usual.

I am wondering this too.

Very Helpfull, i took many notes! What about Cadmium?
I don't use cadmium or selenium, or uranium, etc.
Hi John. Thank you for wonderful series! If I may suggest I tiny correction about nickel - it is NiO or Ni2O3.
Yes, Black Nickel is Ni2O3 and Green Nickel is NiO but this is a general overview. I also didn't include various valences of Co, Cu, Mn, etc. But thank you for writing!

I am not non-partisian but keep it to myself...no one wants to hear it.
