Cyanotype on biscuit fired ceramic tiles created in sunshine

The demonstration version of my cyanotype on ceramic lesson available for Patreons. I’ll chop this up to go with the presentation that looks at the finer points of the process.
It goes out of sync towards the end but stick it out! The last bit is important. This is just meant to be B roll for the cyanotype on ceramic lesson for Patreon. So forgive me offering sub par entertainment! Head to Patreon for the better than par stuff 🤣❤️

Jo, I recently got a kiln and I have been doing Cyanotype for the past year on paper. Is there any safety concerns for firing in a kiln? I have my kiln vented from the bottom to the outdoors. I can't find a lot of info for the firing of the cyanotype but I would love to try it.

Don’t varnish if you are going to fire. I would fire overnight when there’s less people to inhale anything noxious but it should be about the same as iron oxide. Do cone 3 firing first. The cyanotype has a burnout point that’s quite low. Good luck! Find me on instagram and let me see your experiments :)
