Hi everyone,

I’m keen to start experimenting with Adox Polywarmtone liquid photographic emulsion but could use some beginner advice. What surfaces work best, and how should I prepare them? Any tips for coating evenly? How does processing compare to regular photo paper?
If you’ve used this or similar emulsions, I’d love to hear about your experiences and tips.

Thanks in advance!

I haven't used the Adox product but I do know quite a bit about emulsions as I make my own.
I believe they recommend using a baryta coated paper; which Adox does sell. Personally I use fixed out older photo paper as I had no success with the adox product.There are a number of watercolor papers that will work quite nicely. Try Fabriano Artistico which will not need any pre-treatment.
So what is it you want to do?
Technically you can potentially coat on anything; you just have to make the emulsion adhere! Adox makes a gelatin for pre coating on different surfaces.
You might need to use a hardener if you find the emulsion is washing off. Use 5ml. 40% Glyoxol
per 120 gms of emulsion.
Please report back here and tell us what results you have gotten. If you have any other questions feel free to send me a PM but there are others on this site that should jump into the conversation.
Good luck!!
Peter

Hi Peter,

Thank you for the helpful reply. Regarding the Fabriano Artistico paper you mentioned, do you use the cold pressed, hot pressed, or rough version? Also, do you apply any gelatin to it before the emulsion, or does it work fine as is? Thanks again! I’ll be sure to share my results after experimenting.

Hi Miha
I use the hot press as i prefer smooth surface
Ive never applied gelatin for emulsion
All watercolor paper is sized so try just applying the emulsion first...i was thinking more like wood or glass applications
You could also try arnheim 1618 paper
I also have used some Japanese papers with success.
Get the book by Denise Ross available through routledge. She gives lots of tips and protocols for making and coating emulsions.
Personally i make printing out paper which prints in the sun..no darkroom needed!
The adox is DOP or developing out hence drveloper and darkroom required
Go and have fun...the world of emulsions puts you in control of your printing and is extremely creative process...!!

Hi Miha - I haven't tried the Adox emulsion yet, but I do feel very qualified to give advice on liquid emulsions. I have been working with liquid emulsion for 15 years or more and have tried Liquid Light, Rollei, FOMA, and also tried making my own. For me, making my own was a little to "fussy" of a process in trying to maintain a constant heated temperature while also stirring it. I didn't have as good results with Liquid Light. Rollei and FOMA both performed the same and I get excellent results from both. I'm assuming that the Adox emulsion will be about the same as Rollei and FOMA. Given the choice between Rollei and FOMA - I use FOMA exclusively now because it is less expensive here in the U.S. Regarding paper - I used Arches Platine for many many years but recently have experienced big problems with a large roll with blotchy white spots appearing in the paper that do affect the final print. I will not use Arches any more and my paper of choice is Hahnamuele Platinum Rag. Bergger Cot 320 works as well. I have heard people using papers like Fabriano Artistico and Bockingford but I have never tried them. In any case, smoother surface paper works best. Neither Hannamuele nor Bergger need any pre-treatment.

Coating the paper - this is the big issue you will have to deal with. Brush coating is the easiest way and the best way when you are starting out. But, there is a long learning curve to eliminate brush strokes and it gets very frustrating. With brush coating, you normally need to coat twice or you may not be able to get your shadows dark enough. If there is a way to keep the paper warm while you are coating will help. You heat the emulsion up to coat with it, but if the temperature in your darkroom is cold when coating, the emulsion will start to set up very quickly and you will have real problems. Coating with a glass rod will give you the best professional looking smooth coating. This is not using a "puddle pusher" like you would with other alternative processes. You need to wrap the ends of your glass rod with mylar tape to build up the surface of the glass rod above the paper and establish the thickness of emulsion when you coat the paper. This sounds confusing and it is more involved than brush coating, but is gives pretty much perfect coatings everytime. You can read more about glass rod coating with liquid emulsion in either Denise Ross's book or (a little self promoting here) my little book on Bromoil called "The New Bromoil Process" that you can get on the internet.

For processing your prints - any normal paper developer works fine and you process it just like normal silver paper.

Hope this helps and feel free to DM me with questions.

Andrew O'Neill seems to get a very acceptable result with hand brushing using a foam-type brush He will hopefully post about his technique

Awagami papers are also worth exploring - their 70gsm inkjet receiver coated Kozo takes liquid emulsion really nicely.
