Finally had a chance to give this a try earlier this afternoon. I'm amazed that it worked so well! Thanks for sharing your method in the article.

Thanks. I was genuinely flabbergasted that it worked so well on the first go - your directions were spot on. The drama of seeing it emerge in front of one's eyes is terrific. It certainly makes the 10x8 back really tempting now.

Yes, it really shines in 10x8. What did you use for bleach? I know sulphuric acid is getting hard to find now

Dilute sulphuric acid and potassium permanganate. I'm fortunate that the Science Dept at the school where I teach let me use some chemicals.

Yes I've seen it. The120ist on YouTube has been trying it out. Looks very contrasty and quite expensive, but has some good features. I do like Bellini products generally.

Hi,

That looks good I think... The only typo I noticed was that acid stop is usually 1:19 and I haven't checked your concentrations for the bleach or clearing baths. The recipe for the bleach is from the Ilford paper (and they offer alternative clearing baths too).

If I'm honest, the rinses could be a bit quicker if you're in a hurry. RC paper doesn't hold a lot of chemistry. You can also do without the first rinse before the bleach and it doesn't seem to matter.

Cheers,

Dave
