This is possible because instant coffee is rich in phenolic acids (otherwise known as tannins) which have the potential to support development. It also contains caffeic acid which which behaves much like a conventional developing agent 'Pyrogallol'.

The addition of ascorbic acid (Vitamin C) improves the contrast and development times, whilst the washing soda is used to turn the solution into an alkaline and to activate the developing agents.]]> 2017-03-28 08:15:04 UTC https://padlet.com/kierajohnsonliddle/fcrazgz21uas/wish/163038043 kierajohnsonliddle https://padlet.com/kierajohnsonliddle/fcrazgz21uas/wish/163043741 - 1l of water
- 54g washing soda (sodium carbonate)
- 16g ascorbic acid crystals (vitamin c)
- 40g instant coffee
- developing tank
- fixer

Optional (pick one of the following);
- 1g potassium bromide
- 10g iodized table salt]]> 2017-03-28 08:40:04 UTC https://padlet.com/kierajohnsonliddle/fcrazgz21uas/wish/163043741 kierajohnsonliddle https://padlet.com/kierajohnsonliddle/fcrazgz21uas/wish/163046581 Assemble the ingredients to make up two solutions; Solution A and Solution B
1) Solution A; mix together 54g of washing soda and 300ml of water in a jar.
2) Solution B; mix together 16g of ascorbic acid, 40g of instant coffee and 700ml of water. If you are using the optional ingredients you should add them to this solution.
When mixed together these solutions should equal 1l of developer, yet you will only need 300ml/350ml to develop a roll of 35mm film.

Combine the solutions
3) Mix the two solutions in a beaker, and stir until the crystals have dissolved completely.

Develop
4) Working in darkness, or using a film-changing bag, load the film onto the reel of the developing tank. Slide the reel on to the spindle, insert it into the tank being careful not to touch any of the film, and secure the lid on the tank to make sure that it is light tight.
5) Working in daylight, pour the Caffenol solution into the tank and develop for a minimum of 15 minutes- agitating the tank three times per minute. 
6) Rinse the film with water several times to remove any coffee residue from the film and then continue to fix as normal.
7) Wash the film thoroughly, remove from the tank and then hang it up to dry. You can then print from your negative.]]> 2017-03-28 08:52:22 UTC https://padlet.com/kierajohnsonliddle/fcrazgz21uas/wish/163046581 kierajohnsonliddle https://padlet.com/kierajohnsonliddle/fcrazgz21uas/wish/163064391 'Post Agriculture' by Gerald Figal

This could be down to one of two reasons.
1- The developing time. 15 minutes seems extremely short in comparison to Gerald Figals 70 minute developing time. For future Caffenol experiments it would be wise to increase the developing time.
2- The solution mix. There was a literal 'blowing up' when solution A and solution B were initially mixed together. This could have caused an issue with developing as there was a loss of solution and therefore the measurements were inconsistent and the combined solution was weaker than intended]]> 2017-03-28 10:18:39 UTC https://padlet.com/kierajohnsonliddle/fcrazgz21uas/wish/163065404
