Slow bisque to cone 08 (or less, if a stronger clay body with grog/sand) and then they’re fired in the barrel after being prepped with organics and chemicals. No further firing after that or the heat would burn off the smoke trails and carbon. Thanks for watching! :)
Fortunately, no I don’t lol. I learned my lesson the first time. I can paint a picture for you,though. It kind of looks like slag. It’s almost like charcoal in consistency and it sticks like glue to a pot. I’ve gotten around it by just sanding the “slag” off without too much issue, but it’ll scar the finish.
That was a quicker reply than I expected! I have a picture and a mediocre 3D model of a pot I fired recently, and it sounds like what you describe. I did however, not add any salts but there could be contamination in my firepit from other times. Mine looks like you forgot a potato in the oven for too long so it got a charred crust. Can I send you a photo somehow, maybe you would be able to tell me if it looks like the salt-coagulation?
@MrDoomperson I try to be prompt haha. That’s interesting though. What kind of clay did you use? I have an Instagram by the same name: connorcaproon. Just shoot me a DM and I’ll take a look
@@connorcaproon451I dont have an instagram but I'll make one and send it! I used a red clay, storebought. I have fired several items with this before to ~850celcius and had no discolourations other than a smokecloud. Only variables I can think of is the wood this time (oak) which contains more acids/tannins that the beech and birch I usually use. Perhaps aluminium and the acids both reacted somehow.
Thank you so much! They are bisqued to 08-06 depending on whether or not I apply Terra sig. I believe I used a cone 6 porcelain for these pots, but they are quite prone to thermal shock. Some sort of buff clay works well after burnishing.
Hey Nancy! In short, they’re chemicals that react with heat and release a resilient, colorful stain deep into the pores of pottery. More specifically, I use copper carbonate (for red fumes), copper sulfate (for a range of colors that sometimes don’t even show up), and salt (acts as a catalyst for chemical reactions and sometimes produces hues of orange on its own).
Definitely not. The wax is just to bring out the latent colors and make them more fluid retentive. Unsealed pots would soak liquids up. Thanks for the question!
I understand your not being thrilled with the results when it is not what you were going for - I am quite familiar with the 'ho-hum' and 'oh well' feelings I have about my own arty obsessions and I find it mildly irritating when well meaning friends tell me that I am the only one who sees the flaws (they are still bloody flaws!) So, I hesitate to be like said friends when I say 'Connor, these are gorgeous!' . I really like the earthy color on these vases - even the 'too shiny' finish!
Yessir! I think I bisque fired these guys to 08 or so? Something like that. Just enough so that they’re structurally sound enough to handle without breaking but still porous enough to absorb colors from the smoke and fumes. Thanks for the question, feel free to ask away!
Haha no but I’m pretty sure it would just leave a uniform, brownish hue. I tried paper towels dipped in iron oxide and it just yielded a rectangle of red. Dried, chemical dense organic yield the best results. Dried corn husks that are saturated with salt (NaCl), dried banana peels (potassium), etc.
Super late response but I don’t think the colors would hold up. The colored smoke is superficial. It would likely burn up at higher temperatures as the color is achieved via dyes rather than chemical reactions.
Have you thought about using a dowel? U could stick into the pot and hold it horizontal, I’m sure if need b u could use something the like crayola model clay to create a damn and may help you spin the pot, if you needed to do that
Beautiful results. Thanks for showing the entire firing and sealing process.
No, thank YOU for watching!
That was one of the most entertaining videos I've seen in a long time. Excellent 👌
I’m really glad you enjoyed dude. Thanks for watching❤️
thanks for posting the pots look great. finish hack ,if you put two sticks across the plastic then pour the wax over the piece wont sit in the puddle.
That is a fantastic idea. Thanks for the tip, Dan!
This process is so cool. Love the videos 😁
Thanks bb cakes❤️
absolutely gorgeous results and i am so wanting to start pottery
Interesting procedure and great results!
Glad you liked it!
Looks beautiful ❤ thank you for the tips!!!
Thank you, I’m glad you enjoyed!
Looks really good. Thanks for the video.
Absolutely brotha!
Cool video. So are they going in after being bisque fired or does that constitute the bisque?

The liquid wax highlights the surface beautifully. What is it? Thanks
Thanks! I believe it’s called mop n’ glow or something like that. There’s better sealer out there though.
Do you have any examples of salt coagulation on the ceramics? I would like to see this

Lovely pots, do you fire greenware or is this pottery been in the klin beforehand? And what kind of clay do you use? Really beautiful work..
😊

what are those colored powders you put in it?

@@connorcaproon451 what chemicals are you talking about? Do you have Facebook where I can follow you?
does the wax make them food safe?
Definitely not. The wax is just to bring out the latent colors and make them more fluid retentive. Unsealed pots would soak liquids up. Thanks for the question!
Lol at the pride in catching the vase. We all feel that way when we catch stuff, even if we don't say it.
Gotta love a good ninja move am I right?
Could you dip the pieces in the wax?
You could. I’ve found the pouring method to be a bit more efficient and more conservative of supplies.
I'm going to try pit firing soon. Never did it before, but your video was helpful.

The empathy is immaculate. I’ll gladly accept that compliment lol. Thank you! :)
Were your pots bisque fired before you put them in the pit fire?

They look beautiful ❤️
Those look really neat.
Thank you!
hi but is it possible to glaze fire after this stage instead of wax?
Hey! Unfortunately, not really. The fumes that leaves colorful, smoky imprints would mostly vaporize at temperatures required for glaze firing.
Have you tried a long thin linear piece of beef?
Haha no but I’m pretty sure it would just leave a uniform, brownish hue. I tried paper towels dipped in iron oxide and it just yielded a rectangle of red. Dried, chemical dense organic yield the best results. Dried corn husks that are saturated with salt (NaCl), dried banana peels (potassium), etc.
Well explained
They look beautiful 😍
I wonder if 'magic rocks' or 'magic flames' would work.
Super late response but I don’t think the colors would hold up. The colored smoke is superficial. It would likely burn up at higher temperatures as the color is achieved via dyes rather than chemical reactions.

Honestly not a bad idea. May have to use that. Thanks! Sorry for the super late response haha
This is so fucking cool dude. RIP to lil bug bro hahaha.
Lmao thanks brotha. Nah, lil bug bro is hanging out somewhere. Just lit his molt on fire, that’s all😂
ahhh hah ahh thats hot ahhhh
Thank you will smith
