NEW55 Monobath Developer? What?

I can't quite figure out whether static on a solarised image should be white, black, or could be either one!

Personally I'd prefer to use Crawley's FX6a monobath which works well and can be fine tuned to match specific films. L F A Mason in Photographic Processing Chemistry lists a typical Monobath formula. Mason was head of Research at Ilford, his editor was G I P Levenson who held a similar position at Kodak Ltd (UK).

Typical Monobath

Sodium Sulphite (anhyd) 50g
Hydroquinone 15g
Phenidone 10g
Potash Alum 18g
Sodium Hydroxide 18g
Sodium Thiosulphate (5H20) 210g
Water to 1 litre

Water must be sftened or deionised/distilled to prevent precipitates.

Use 1+1, 600ml working solution will process 6 rolls of 35mm/120 film, minimum Development time 7½ mins between 15.5ºC/60ºF and 26.5ºC/80ºF

I've not tried this particular monobath but suspect it's similar to Ilford's Monophen which they sold commercially.

Anybody who made blueprints in the "old" days never got a head cold because the Ozalid process was Ammonia based.

I was lucky because the place I worked had a Bruning machine that DIDN'T use an Ammonia process.

I did this as a comparison shot (I was comparing with a paper negative) using FP4+ in Don Quall's monobath:

Saw this today.

How can this work? It develops, stops, and fixes, all in one bath in 6 minutes and can be viewed with safelight after 2?

This can't be archival can it?

How does it work?

I guess if it was any good all film would be developed like this
