This is john britts copper red recipe i revived from a cone 6 glaze book. its very hard to get reds in an oxidation kiln but with the magic of silicone carbide its made a little easier. in this video we not only test this glaze in my old skut 181 but we also see what we can get from a brown, b mix, and porcelain test tile alone with some of the regular glazes i use .

Silicone carbide digital fire note: digitalfire.co...
soooo... normal electric kilns always produce an oxidized firing and the only way you can get a reduction firing is in a gas kiln? I'm kinda new to working with kilns and I find the redox portions to be the most confusing!
that's not the only way but the reason that copper turns red in a kiln is because of the reduced amount of oxygen which is why they call it reduction firing. It's not as though I've never seen a red come out of an oxidation kiln it's that it's just much harder for the chemical reactions from chemicals that turn red such as copper to happen. Silicon carbide creates little pockets a reduction ( I'll put it that way) and that's what helps the red come out of the copper inside of my oxidation with this recipe
Regan F. Reduction just means reduced oxygen, a living flame either gas or wood can be controlled to reduce the amount of oxygen in the chamber. Also using a sagar can work. There are a number of things to take into account so take a workshop with a potter who uses the process.
You can have a reducing atmosphere in an electric kiln. You need to add something to the kiln when it is firing. Some people add propane to it. Some people add carbon monoxide to an electric kiln, "you need a license to do that" some people put moth balls in an electric kiln and some people drill a hole and mount a Bunsen burner under an electric kiln to reduce the kiln. And then some people put fine mesh silicon carbide in the glaze to reduce the glaze. If you are just starting out spend time making pottery and using what is available. As to reduction and what is reduction. On the molecular level, lets take red Iron Oxide. If we reduce it and take away an oxygen molecule we get iron. Which is a very strong flux. If you reduce Copper oxide or copper carbonate and remove the oxygen from it you get metallic copper. It's science and not voodoo.
Pro tip: watch series at kaldrostream. Been using it for watching a lot of movies these days.
@Jax Amari definitely, I've been watching on kaldrostream for years myself :)
please note for those who keep asking me what combo the inside of the bowl is.... its not a combo.... thats just 1 glaze... that is the glaze recipe
Yo -baby poo looks dope! Ninja turtle snot yellowish lime green is top notch. I'll give you 2 thumbs on both my TH-cam accounts.
Is it bad that sometimes I watch your videos because they make me laugh? So thankful you share your sense of humor.
I made the John britt’s copper red cone ten. In reduction it’s very smooth red with slight blue bits where it’s pooled. I love the variation you’re getting. Maybe I’ll add more copper carb.
I agree with you, Baby Poo. I like the first glalze with the red rock clay and the blue outcome and the porcelin. Thanks for all of your sweat over that hot kiln.
I love ur lumos glaze sooooo much! 😍😍😍
I made this glaze & it came out purple & white instead of red & green. Actually, none of my glazes were coming out correctly. I realized that it was because I'd used tap water from my new studio & it's got a higher mineral content than other places I've worked.
An older fiber artist working off of the same well said that she runs a dehumidifier & uses the water from that to make dyes because it's akin to distilled water you'd buy at a store.
Looks like I'm retesting all of my glaze recipes during the quarantine.
a large portion of what I'm finding out as how to calculate specific gravity and half of my glasses don't come out proper color because they have too much water in them.
@@EarthNationCeramics I did a test of a couple of my glazes with varying levels of water, thinking that was the issue, but the colors were still off.
Beautiful test tiles and pots! Really nice glaze!
Great video! I love the results of the original glaze without the red iron and mason stain. I'd be interested to see it with a thinner layer of glaze because with copper reds at cone 10 reduction you have to hold the piece in the glaze bucket for a long time like 8-10 seconds (or at least the copper red I've used, it doesn't run at all either)
I love this color combo so much 😍
Beautiful glazes Dante!
And i agree with you on your view of yellows and the fact that it looks like baby poo
I think you should test it with a different Mason Stain added. Maybe it would give you non-baby-poop base color - maybe blue or red - but if you use a darker stain you will probably need to decrease the quantity. If that works could you just add the Mason Stain on demand?
Does everyone tell this gal she looks like Mary from Downton Abbey? I can't get over it! Beautiful :)
Lumos! It’s beautiful, Dante. Please post the link to the recipe.
Thank you, this looks great!
Nice video man never a time I thought otherwise
Do you or have you shared the recipe for the lumos? The white and blue cup.
What is FFFF? I have doubly rare Danish lamp circa 1920. Few were made and my non lava was made fewer. In learning the history i read a lot on SiC and a consistant two principles were using varying heat-times and the larger the grit the more the pit. The finest i can purchase from a brick n mortar shop here is 12000 grit
F stands for fine and every f is 200 sieve. This is 800
So the "P.......yellow" mason stain you tested with iron oxide gave you the poo. What would the canary yellow mason stain with iron oxide (as stated in the recipe) given you?
"Read the description for the glaze recipe you unfried chicken nugget!"
Lovely😍
I wonder what a lil rutile in the glaze might make it do hmmm
Would you be willing to share your recipe for Lumos?? It is incredible.
It is in another video but only the recipe, no test tiles nor examples.
Can you tell the tile of the Lumos recipe video? Thank you 🤗
Limos recipe please?
Dante... I agree with you with the baby poo... I don't like red and green, they don't compliment eachother to my standards..
Haha, so funny & Thank you!
You speek about red oxydation cône 5/6 from John Britt but you don't give the recipe... ! Can you help me ?
What specific gravity did you have the batches mixed to?
Why are your test tiles so miniscule?
Have you tried amaco pc 70 copper red? I can’t seem to find any combos for this literally none.
Whenever you say,”baby poo”….I think you mean “meconium” (which is olive greenish fetal feces)😮😮😮😮😮.
And there is the dragon ball scream!
I love you lol
Really, Donte, how much baby poo have you seen for real?
