Adox Polywarmtone (Pic: Adox)
Adox says the emuslion can be used on a range of materials (Pic: Adox)

Adox has announced a new warmtone emulsion for darkroom photographers.

The new Polywarmtone emulsion is a retro-looking gelatin-based emulsion which can be applied to a range of materials, including prints and glass plates.

“Originally a legendary paper from Forte, its recipe would have been lost in the digital revolution, if not for Adox saving the production technology,” the German film producer said in a statement. “It took the company 10 years to recreate this naturally warm, beige-green, high-definition, extremely vintage-looking emulsion – and now it is available for artistic work on a variety of surfaces. And it has a superb toning response too!”

The 300ml bottle coats between 2.5 and 3 sq metres (26.9 to 32.3 sq ft) but can only be used under safelight conditions. Adox said he jelly-like emulsion has to be treated in the following way to become useable.

  • Be heated to about 42-45°C to liquify.
  • Adhere well to the support while drying (in total darkness). The emulsion may only be exposed to red light for two to three minutes, or about 10-15 minutes under the Adox Supersafe darkroom light.
  • Harden during the processing (become less soft, more resistant to touch).

“Adox is also releasing an emulsion hardener EMH-1, which can be used as a standalone bath or preferably added to the stop bath,” the film producer added. “Adox Colloida C is a special coating gelatin, which is used for better adherence and emulsion spread over alternative surfaces.”
