Thanks for adding these videos Linda ... you make it so clear and easy to follow. My dream is to actually get to one of your glazing courses in the future but for now, this is great xx
Hi Linda! I've looked you up on youtube as I'm considering buying all three of your books. Respectfully, I find your books somewhat intimidating. :-) Finding your youtube videos has helped me get past some of my intimidations. After watching I recognized your books are not so intimidating but, rather that they will take me beyond my level of effort, I'm a lazy hobby potter. :-) Taking my comment full circle, I'm definitely purchasing all your books. LOL I recognized from your videos, just how interesting and valuable your information can be to me. I recognize by watching just how much I'd benefit by understanding more about the commercially purchased glazes I use. So, THANK YOU you for the books and videos!!! I hope you will continue sharing information!
Thank you RH, I’m very happy to hear the videos have made the books more accessible. I only recently found time during lockdown to make the videos but have now made a longer online course explaining more of the glaze chemistry from the books. You can find the online course on my website. lindabloomfield.co.uk/membership-account/membership-levels/
Thank you for this video. I have some questions. Why do you mix the glaze with your finger 2:10 while you are wearing goggles and mask being so afraid of dust? What is the difference between colored glaze and oxides?
The glaze ingredients are not soluble in water. Fur this reason they will not be absorbed into you skin. A coloured glaze is one that contains colouring oxides or ceramics stains made from colouring oxides. These colouring oxides are the concentrated form of the coloured pigment.
Great demonstration. This has helped me so much. How much glaze is in your container or does this not matter as long as the oxide additions are incremental? I've done my line blends the opposite way.
Can I ask what the difference between oxide and carbonate is? Sorry if that's a silly question. And can carbonate be used in a glaze for dinnerware or should it only be for non-functional pieces? Thank you for the video
Carbonates change into oxides during the firing, when carbon dioxide is given off. So the end result is the same but you need 50% more carbonate to get the same colour intensity as an oxide. Both are fine to use in functional ware as long as you don’t add so much that it turns black with a metallic sheen.
The glaze recipe I gave in my ‘How to make a glaze’ video is really for cone 8-9. You would need to add around 15% borax frit to make it melt at cone 6. The colouring oxides can then be added in the same way.
I m looking for information on oxides mixing with glaze that make crazy colors like iridescent I don't know what to buy where to look and if they work with low fire pottery
@@lindabloomfield9773 I m talking about layering glazes and some recipes look almost that way. Not like lusters I only do earthenware but I was looking for mid fire look with it

Hi Linda!!! I just wanted to say how awesome your video is! It's super helpful and exactly what I was asking for. Greetings from North Carolina ❤

Thank you Suzi. I have now made an online glaze course which you can find on my website.

@@lindabloomfield9773 Thasnks for the information, I will look into it ASAP...Be safe and thanks again!
@@lindabloomfield9773 BTW the books are on the way to me now...LOL see ya!
Hi Linda, great video. What temperature would did fire cobalt oxide brushed onto earthenware bisque with a clear glaze on top? thank you! Sasha
The firing temperature depends on the melting temperature of the clear glaze you are using. For earthenware it would be 1060-1100°C
How this ingredients glaze making
See my video on How to make a glaze

I’m adding to 100g dry weight or roughly 200g wet.

Hi, what is the recipe for the transparent glaze you mix into ?
This is a cone 9-10 transparent glaze,
Potash feldspar 27
Quartz 32
Whiting 21
China clay 20
Would this glaze recipe work on stoneware fired to cone 6?

Try lustres. They need a third firing to 800°C.

@@damlasminiatures2526 try searching for metallic glazes on glazy.org
@@lindabloomfield9773 no I mean talking about pastel colors n some other colors. Not metallic
@@damlasminiatures2526 you could try using bismuth but it’s easier to buy ready made lustres fro iridescence

For,me,it's a bad idee to write the name on the lid because a mistake is rapidely made with de lids .... I always write the name on the pot !
