I'll just copy paste Habib's post: 1
Mar 7, 2025 #cyanotype #CHIBA #dichromate #cyanotype #CHIBA #dichromate Part 2 of a new process, inspired by CHIBA, that doesn't use animal products nor acids. It requires Ferric Ammonium citrate and two polymers: Gum Arabic and a cellulose derivative namely Methylcellulose or Carboxymethylcellulose (CMC).
Formula for a 100ml sensitizer solution:
10gr Gum Arabic (powder)
5gr Ferric Ammonium Citrate (powder)
1gr CMC or 1gr Methylcellulose (powder)
100ml of distilled water.
Directions: a) Expose in warm temperature environment 20°C or better b) Develop in 0.3% Hydrogen Peroxide at around 35°C c) Rinse in warm water at around 35°C

Have a great week and see you in the next video.
On the first post he had:
2g CMC in 100ml of water
200g gum in 400ml of water
25g FAC in 100ml of water
developer 0.3% hydrogen peroxide -> buy 3% and dilute 1 part in 9 parts of water.
then he made a 2-1-1 mix:
2g/100ml CMC
100g/200ml Gum
12.5g/100ml FAC
resulting in 400ml solution
to make the new mix:
1gr CMC or 1gr Methylcellulose (powder)
10gr Gum Arabic (powder)
5gr Ferric Ammonium Citrate (powder)
100ml of distilled water.
The already prepared stuff:
1g/50ml CMC
10g/20ml Gum
5g/20ml FAC
resulting in 90ml solution or a 10-1-4 mix
