Bronzing effect with Ilford Multigrade RC Gloss

[NHW]

I posted a while ago on this subject and got some helpful replies but none really solved the problem which is this:
I use fresh Ilford chemicals, adhere to recommended procedures etc. I have a good safelight. The prints look great when viewed straight on. However when angled towards a light source, the blacks show a blueish, metallic effect very similar to that seen with inkjet prints. I do not see this on glossy fb prints.
Has anyone else seen this? Does anyone have any idea what's causing it. These are new, not old prints.

I had to go look at the prints, but see no issues w/ mine that were printed on that paper w/ several different types of developers and fixers. I wonder if you got a bad batch of papers? The only time I experienced bronzing was w/ inkjets years and years ago.

While we're on this subject, I'm not happy w/ the reflections that come off the MG RC GL papers. They're all over the place, and there's no issues w/ FB GL papers. The FB GL Foma papers don't do it so much.

This is what I see in the blacks when the print is angled in the light.

Your best bet is to contact Ilford itself. There is a link on the web site that is aimed to help with problems.

mcfitz, thanks I did that. They didnt know what's causing it. I sent a couple of images for them to view. Waiting for a further response.

Rockland Halochrome uses a version of Tollen's reagent to produce a silver mirror look. You don't have formaldehyde laying around???

I think I've seen this effect before, maybe not as pronounced. Like you say it's not uncommon in older prints.
