TF-2 Alkaline black and white fixer
Since I tried the formula #134 from classic “The Darkroom Cookbook” by Steve Anchell, the TF-2 Alkaline Fixer, didn’t need to buy ready made commercial fixer again.
Here is the Formula I use (by Bill Troop):
|Distilled water (~40˚C)||750,00 ml|
|Sodium thiosulfate (pentahydrate)||250,0 g|
|Sodium sulfite||15,0 g|
|Sodium Metaborate*||10,0 g|
|Water to make||1.0 l|
*Sodium Metaborate can be hard to find depending on where you live, but you can substitute it with 7g of Borax + 1,5g of Sodium Hydroxide (Caustic soda)
The process is extremely easy:
- Start by adding the sodium thiosulfate to the water and stir until dissolved.
- Add the sodium sulfite and the metaborate and stir well until everything is dissolved.
- Add distilled water to make 1 liter and the fixer is ready to use.
Keep in mind is not ideal for new tabular grain films as Ilford Delta or Kodak T-MAX, it takes a long time to fix, but for classic films as FP4 or HP5 works as a charm.
With one liter you can fix around 20 rolls of film, it’s odorless, and lasts for about 2 months. Highly recommended!
