A few days ago I coated some paper with turmeric extract in anticipation of the next sunny day. Yesterday was that day!
I set up eight printing frames for exposures (four on 5×7 paper and four on 8×10 paper) and had them out in the sun by 10 AM. A little after 4 PM (i.e. a six hour exposure), I removed the paper from the frame and sprayed with a solution of washing soda (sodium carbonate). This changes the bright neon yellow of the turmeric to the nice red-brown you see here and (hopefully) stabilizes the print against further changes upon exposure to more light. Borax is more commonly used for this and gives a fairly neutral brown. I like the red-brown seen here better!
I think these four might just get matted!

Great effect!
I think they should be framed as well.
Here’s hoping any future exposure to the light will NOT impact the prints.
