Weird effects on developing MG paper

[digiconvert]

For the first time in a while I have been at home when it is comfortable to work in the darkroom. The first test print came out with a 'golden sheen' which I presume is metallic silver over the paper, very effective but not a great deal of use in this instance. I am puzzled as to it's cause.

Ilford MGiV paper developed in Ilford MG at 1+9 (20C) for 90 seconds followed by stop (1 min) and fix ( 2.5 min). Dveloped in a Unicolor drum, hand agitation. In short my usual procedure (unless the heat has fried my brain). The Dev has been opened about 6-8 weeks and been used twice I think, again not an inordinate time , but seems to be rather yellower than I would expect and on inspection has a suspension of some kind widely dispersed in it. Last time I used the drum I had to clean a black residue from it.
Is it possible that thr heat has caused the dev to oxidise quicker than normal or is it the paper or both ? And how come the silver has deposited all over the paper ? (it scratches off before wash/dry)

I've ordered more dev/paper anyway -given me the chance to try Ilford cooltone- but am curious.

Cheers Chris

I tried to develop some Ilford MG paperin MG developer last week. Unfortunately, my concentrated developer came out of the bottle almost black. A bit like flat Coke!

I tried it anyway but it was no good, very flat looking print with very low contrast.

Mine has been in my darkroom which is in the roof of my house and it would have got quite hot during the last few weeks. I did not see a silver coating on the print though.
