Cliché verre "photographic" process?

jsmoove · Apr 6, 2021

Before I leave the soot train....what temperature does soot turn into carbon dioxide?
Carbon trap glazes: https://digitalfire.com/glossary/carbon+trap+glazes Says that carbon burns away over 1500F.
Also that soot article I linked above says that a candle gets to 700C (1300F), so it would have to be above that since the soot is being created and not disappearing into a gas.
I've seen in a wood fireplace soot covered glass, and that soot doesn't go anywhere. In fact its quite hard to get off.
I imagine the soot is not bonded to the glass though, but stuck on. Can it be made permanent and one with the glass? (enlightenment)

@jsmoove That CNC based candle video. When I saw this thread I thought I would make also CNC based Clicé verre but so that I scratch the soot with CNC. I wrote a test software for it with processing.org which converts image to curves but then I thought maybe it is too "computer".. Maybe I should try it I just bought 8x10" glass plates (for contact printing) .. Hmm ..

@vedostuu That is a great idea....and makes way more sense, to etch it out instead of just burning the candle like in the video. Ive always wanted a plotter... They look like so much fun.

Same idea?
Not sure what the highest resolution you could get with a cnc is, I suppose the higher you go, the longer it'd take to make?

It's true, it would be a photomechanical process. I'm not sure how easy it is to use soot for a photographic process as I'm learning here, though @Vaughn stated some great carbon based ideas.

A bit same idea but yours is better. That TSP would look pretty interesting!

@vedostuu I think anything more photographic looking made of soot would be super cool, I would love to see a CNC'd soot image.. I'm not sure if TSP is the best way, but it's the only thing I could think of for a possible higher resolution...or pointillism?
@Vaughn I'm reading: https://enamellers.net/enamel-photography/
And the paragraph about the dusting on process with pine soot sounds like you expose ferric citrate , then the soot would stick to the tacky non-exposed parts, then apparently coated with rubber
Im not sure why pine soot (or what they mean) but could candle soot work too?

Pine soot probably contains resins.

One of my favorite teas is dried over pine wood fires -- the resins gives a pine taste.

You can probably use laser ablation to create the image on soot.

@nmp That would definitely create a higher resolution.
After watching: (8:30)
It's now obvious as you said, the carbon would be gone at high temperatures.
However, there is carbon trapping in ceramics, not sure if soot can be trapped or not. I'd think just putting a clear glaze over the soot would do the trick....im no potter though

What about a candle made of turmeric?
Lol...
Candles do not emit UV, would the turmeric be deposited along with the carbon? Then expose after coated?
(yes, why not just coat turmeric on glass, I know)
In this case I am more curious about the strength of deposited soot on the glass.
Maybe any emulsion could be put into candle form, I figured turmeric since it wouldn't hurt your lungs if you accidently breathed it in.
