Thread: Scale rot example

I agree, it has to be assessed in-hand.

With mottled celluloid it is true that the steel under clear areas is more affected than under dark, opaque areas. This is usually because dark/opaque areas come from a different mix, usually containing a large amount of filler (usually powdered asbestos) to take the colouring and make a solid colour. That means this type has less acid releasing celluloid, so the marking on the steel is not as severe.

In this example the darker areas seem to contain just dye, so something else is happening. Either the razor has been kept in the light and the light celluloid has transmitted light, drying the vapour and concentrating it. However, it might just be water already on the blade in conjunction with a phenomenom akin to 'pattern staining' that you sometimes see on the walls of plastered/rendered buildings.

In this case the staining is caused by heat differentials. Warm areas encourage airfow wile cool areas allow the air to move slowly. Warm air can hold more moisture than cold air, so cooler areas get water deposited on them, and stain.

Or it could be a combination of both. If it is celluloid, then part of the breakdown process is the liberation of water vapour along with corrosive gas.

Yes, just like Brad Maggard's example.

Don't get confused, I have not said that your example is not cell rot, and I don't take too well to sarcasm, either...

Take a good look at Undream's example: the rust pattern is distinctive, unlike the first example you posted, which incidentallly got a mixed reception on the UK forum you posted it on too.

An all-round good reception for you on the other US forum, though. Pity us 'so-called experts' got rubbished in the process, though. We only try to help, and offering alternatives is part of that process.

For my part I am quite happy to ignore any further postings of yours, because I hate cross-posting, especially if ridicule is the object, and I don't enjoy seeing knowledgable people disrespected.

My good friends Jimmy and Shooter have vast experience - they don't deserve the kind of disrespect a comparative newbie has shown them.

Dang! Rot and rubbish, disrespect and righteous indignation. My faves!! Wifey is sick and I am running washer and drier...
Missed the party!

I think if members are going to get all riled up over something cel rot is about the last thing worth any vitriol.

Maybe we need a virtual arena where folks can go and settle their differences.and after that they can go to the virtual pub and

Yea, two things never to discuss in the forums, cell rot and shiny blades!!!

I've never been able to get a blade to pass HHT if it has cell rot ....... not yet anyway ....... maybe if I honed it on a coticule ........

Think I'll pass on the arena and go straight to the pub ... virtual hangovers are so much easier to deal with, dont'cha know...
