Demonstration: Cyanotype on biscuit fired ceramic tiles

[@MrMikaeljonson]

Wonder if you could use transparent glaze and then glaze fire to seal them instead of using varnish

[@JoHowell]

If you get a low fire glaze or low fire the cyanotype cone 4 then glaze after. It will turn orange :)

@@JoHowell oh that would be interesting to see!

Hi Jo! These cyanotypes are absolutely beautiful! I’ve tried this technique before, but I didn’t pay enough attention to my porcelains, and they eventually faded to a greyish hue. I think I didn’t put in enough effort with the cold washes, which allowed them to continue developing. Do you have any tips for stopping the development process on porcelain? Also, what varnish do you use at the end? Is it UV resistant? I really want to try again but this time I want to make sure my cyanotypes survive

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.

[@JoHowell]

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 :)

Hi Are these bisque fired porcelain tiles?

[@JoHowell]

Yeah :)
