Title: Bronzing of CD's.
Post by: Irons on February 28, 2020, 07:44:28 AM
If this subject has been raised previously then I apologise for doing so again. But a genuine concern so here goes.

I would say that most, as much as 90% of my purchases on the CD format are pre-loved i.e not new. Some I have noticed have a bronze hew instead of silver. Should these be avoided? - which makes a mockery of Philips claim of "Perfect sound forever".  Two questions: Is bronzing a sign of ageing and does it have any bearing on replay quality?

Bronzing was a normal thing years ago when PDO pressed CD'S of faulty material. I have a few on the label Albany and Hyperion. Eventually these CD'S will degraded to the point of not playable anymore. After this PDO disaster I have no knowledge it ever happened again. So yes avoid them.

Adding to Harry's comments, the defective CDs were manufactured between 1988 and 1993, and would have become unplayable by now.  Any CD that plays now is probably not defective. Usually the outer edge (the end of the last track) is the first part of a disc to be affected. There are also CDs that were manufactured with a yellow dye in the plastic to make them look golden. These are not a problem.

Hyperion has a useful page with information on "bronzed" discs.

Or copy them to other media on a computer. I’m copying a load of mine as unaltered AIFF files to two hard drives from which I can make further copies in whatever formats I want for my playback devices.

Irons,

Are they still playable?  Fingers crossed for you.

I recently avoided purchasing a set (forget which label it was on....think it was DG?) as it had the old foam inserts--one of which was stuck to the first CD!  :-(

Yes, bronzing on CDs is definitely bad news. If they are important to you then I would start the processing of copying straight away. I had a few in my collection and they eventually became unplayable.

The only label I had problems with was Hyperion. And I had the best experience with them: I wrote to them that the disk(s) was unplayable, and they had me send them some info off the disk itself to verify I actually had it, and then they sent me the entire disk as FLAC files. In all 3 cases (over 2 years) where this occurred, they told me they would have just sent me a new pressing of the disk but they didn't have any remaining. I am very fond of Hyperion, needless to say.

 PD 

I had this same experience, couldn't avoid it as it was already mine.  I count myself fortunate that I was able to rescue that disk, and immediately searched for others that could have the same problem. I wonder what they were thinking?  ???

As someone pointed out "bronzing" in the strict sense was a comparably local problem that mostly affected a bunch of British labels (but also Nuova Era and Tactus from Italy and DG).
Beware of older (used) hyperion but their more recent (;) after 1995 or so) ones or re-issues would not be affected. Note that the special problem with Hyperion is that many of their disc regularly have a golden tinge, so bronzing can be much harder to spot.

Effectively, I have about a handful or so of bronzed CDs. I lost the Mozart c minor mass with Fricsay on DG resonance many years ago to bronzing. Trying to burn a copy was too late or the late 1990s/early 2000s soft/hardware I used was not up to the task. I also once got an already unplayable hyperion from ebay (I think the seller refunded me when I complained; he had not been aware of the problem). Then I have two or three more hyperions (one from the Goodman Haydn, one from King's Purcell series) and one or two more DG Archiv (Pinnock with JC Bach chamber music and the Haydn Stabat Mater) that are discolored but either still play or I made copies in time). All of them were very evenly discolored, never showed the characteristic pattern found in online sources with the outer section much darker. But I got one of the latter, too, it is a Corelli sonatas anthology from Tactus I got sealed! (new old stock, I guess) from Ebay.

The old foam inserts should be removed immediately! They are more than useless (only during shipping/transportation can they help protecting the discs) because them getting stuck can be as bad a problem as any. Although one can usually remove them with warm water and some mild agent without too much damage.
Title: Re: Bronzing of CD's.
Post by: Ratliff on February 28, 2020, 10:43:37 AM
FWIW, I never remember finding a disc I had purchased new had bronzed. I purchased a disc in the last few years that arrived "bronzed" and it was utterly unplayable - wasn't even recognized as a CD by the player. Got refunded by zoverstocks without question. By now any defective disc has deteriorated beyond any remedy, I think.

I did notice at one point that holding up an old CD to a light I could see pinholes. They played fine, nevertheless. I don't know if that was deterioration or just manufacturing quality. In any case, I've got my CDs copied to hard disc (Flac) so it is hard disc corruption, not bronzing, that worries me.

The only one that I have, so far, had a problem with was the Bantock Hebridean/Celtic symphonies on Hyperion, a few years ago. I contacted Hyperion about it. They asked me to send them the CD and they then immediately exchanged it for a silver CD which played properly.

Post by: Irons on February 28, 2020, 02:34:25 PM
Thanks gents, and PD. I must be unlucky as coming across quite a few lately which prompted the query. I thought it likely not be good so not purchased, but yesterday forgetting to check I paid £5 for a Nimbus CD (manufactured by themselves) of William Boughton conducting English music for strings. The bronzing is quite bad, being a regular  customer I’m sure they will take it back. If they argue I will show them your posts!
In future I will note the labels suffering from this problem.

Very true. Many of my old opera boxes (the Solti Ring especially comes to mind) experienced severe degradation/rotting of the foam inserts, which were adhering to the back of the discs. It was alarming; I gingerly removed all such inserts and fortunately the CDs continued to play as before.

Oh, dear, I may be the reason you had to send in the CD first, because originally I believe they'd just replace a CD immediately on request.  I did not send in my bronzed CD after receiving the replacement.  I am bad man.

Does CD bronzing make it so the discs can't be ripped? I have some old CDs with pinholes and those can't be ripped.


(It was Svetlanov's Antar on Hyperion.)

Ran to pull this one out of storage, completely bronzed!  ??? Damn, I ripped this one decades ago when I was still listening to MP3.

To my knowledge, it still plays fine with no issues.

Post by: aukhawk on February 29, 2020, 01:29:36 AM
Usually the outer edge (the end of the last track) is the first part of a disc to be affected.

In that case only very full CDs (long playing duration) would be affected - anything up to about 65 mins is nowhere near the outer edge.  In any case that is my experience with over-stuffed CDs in general, if the duration is well over 70 minutes the last couple of minutes are the most problematic.  With any luck the last track is a filler that doesn't interest me anyway!

Does CD bronzing make it so the discs can't be ripped? I have some old CDs with pinholes and those can't be ripped.

Audio CD players are designed to play audio CDs in a fault-tolerant way - computer CD drives are not.  So in general if there is an audible fault on a CD player that problem will almost certainly be present when ripping.  On the other hand, good ripping software can be set to scan problem areas several times (a very slow process) with varying degrees of success.

Post by: Jo498 on February 29, 2020, 02:03:48 AM
That's a good picture of the "typical" bronzing. However, there are also very even and slight discolorations that are almost impossible to distinguish from the slight golden tinge some discs do have originally; of my 5-7 (possibly) bronzed discs, only one or two had the "typical" appearance, I believe.
Title: Re: Bronzing of CD's.
Post by: Que on February 29, 2020, 04:38:31 AM
I all my collecting years, I’ve only come across bronzed CDs three times: on Pearl, Hyperion and Tactus.

The Tactus was only recently, I guess the disc had been lingering in storage for decades.
I replaced the disc with that of a cheap reissue, and kept the case with the original, elaborate booklet.

I have purchased a few CD's in the past that were described as new and were heavely bronzed and unplayable (EMI) I have still a few that are lightly bronzed and they are stable now for some years. Those foam inserts were also horrible.

It did rip fine in EAC secure test & copy, but still makes me a bit nervous for probably dozens of others still lurking in boxes that might not.

A big thumbs up to eBay. I purchased a used CD on the site of a Chandos CD of the Bax Piano Quintet/2nd String Quartet. The Quintet played perfectly, and very good it is too. However, halfway through the quartet the music started to brake up badly. I nervously placed another CD in the tray which played faultlessly.

At £7, keep - the quintet was reason of purchase - or return. I decided on the latter. It could not have been easier. A short message to seller then on "My eBay" a pre-paid tracked postage with the return address popped up to print off and tape over the original packing.

I have had three or four defective CDs in a hundred or so. Is this normal? (I purchase mostly 2nd hand) I have not read any comments on GMG on this subject.

Was it bronzing, scratches or a factory (pressing) flaw?

I only encountered bronzed CDs three times, but it depends on which labels you buy. It's a thing of the past, but can be encountered when buying used
Factory flaws only a couple of times (say five).

With 2nd hand things get trickier... 
Sometimes it's just dust or finger prints, and a piece of paper kitchen towel with a alcohol based spray is a good fix.

I hate scratches... How on earth do people scratch their CDs?
Unless the disc is not always either in the case or in the player?  ::)
This why I never buy "good condition", but new or like new.
If it is something I really want, I'll take a chance with "very good"...

Used or new old stock. It's probably about 8 years ago now but I once got a sealed disc (Tactus) that was bronzed. It had probably remained sealed for about 20 years in some warehouse or so...

CDs are quite robust, so I also wonder how some people manage to scratch them so badly. But there are some cases and apparently also some player (older car players?) that can produce scratches, I believe.

Not bronzing, this seemed a convenient place to post query. The Bax CD appeared fine without scratches so assume a manufacturing fault but admit not attempting cleaning with alcohol, maybe I should have tried that. I understand all players are equipped with error correction but I wonder with error correction working at full tilt the quality of sound suffers? My knowledge of digital recording technology is minuscule.
A guess-estimate of CDs on my shelves was conservative, at least double that, so buying used roughly 2% purchased are unplayable due to faults. I would double that at least buying vinyl.

Flac and (if possible) offsite copies.
Some photographers are pretty serious about so copying/taking inspiration from their backup system a good idea.

Post by: Pohjolas Daughter on June 08, 2020, 03:43:11 AM
Irons,

I ran into problems with one eBay seller (a big small company if that makes sense) which would auction off CDs claiming that they were 'as new' (or other such words); I received one 2-CD set from them and realized that they were re-surfacing them (basically taking a thin layer off of the shiny side).  The way that I discovered this:  the first CD was pristine looking and the second was badly scratched in a number of areas!  Some CDs that have had this 'polishing method' done to them will play fine, but it can also vary depending upon how sensitive your CD player is.

Note:  depending upon how deep the scratch is, even this method may not work.

PD

I overall had very few bad used CDs among the many hundreds or even thousands I have bought over the years. Sure, I got around 3-5 bronzed ones (but with the very even kind of bronzing one could hardly blame the seller as there are some discs that look like that without being bronzed) and a few scratched or dirty ones (that would play anyway most of the time). I was probably more frequently angry about broken cases (if non-standard cases that are not easily to replace) or booklets in a bad state. And with many sellers the "like new, very good, good" is not very helpful. I have received "good" ones that were like new and supposedly "very good" ones that showed marks or had pages of booklets missing etc. The professional resellers buy them in bulk and cheap part time labor puts them online; they are not going to spend a lot of time writing descriptions...

I must be unlucky. Compared with most if not all forum members my CD collection is miniscule and yet here we go again! Seriously miffed to receive yesterday a full priced Dutton CD (new but not purchased from Dutton) still in shrink rap in a bronzed condition. I will get my money back but I am unable to listen to a piece I was looking forward to when I wanted to.

Post by: Jo498 on September 10, 2020, 11:56:15 PM
Maybe you are, but you are also in the UK which was the main "basis" of bronzed discs and labels like ASV and Hyperion were among the most afflicted. I also once got an old stock still sealed disc from Tactus (Italy) that was already bronzed. And I once or twice forgot to never buy old used Hyperion or ASV discs and got 2-3 bronzed ones.
There are other ways discs can be faulty but if someone acquired a huge collection in the last 10 years mostly on the basis of these huge cheap boxes with dozens or >100 discs that are all fairly recent, he will not have any bronzed discs because this particular fault only concerns discs that are ca. 30 years old.

Title: Re: Bronzing of CD's.
Post by: Jo498 on September 11, 2020, 02:42:47 AM
No idea. The additional problem is that some hyperion discs do regularly (i.e. without being "bronzed") the bronze-ish color. That's why it is often very difficult to see. Of the handful of bronzed discs I have seen only one or two had the typical discoloration pattern with much darker zones, all the others were so evenly and slightly discolored that it might as well have been the real proper color.
Usually the playback problems start on the last track(s). My first bronzed disc was Mozart's c minor mass with Fricsay on DG resonance. For a long time, I could still play all but the last one or two tracks.
I'd rip/copy the disc ASAP and then you will probably be fine. Or maybe ripping/copying will already exhibit some reading problems.

That is good advice because, in my experience, the deterioration is gradual. So, it may be fine today but in say a year's time it may be unplayable. I would certainly rip it now to be on the safe side.

You have hit nail on head, aligreto. I have since discovered the vendor is in fact Dutton trading under another name on eBay. After emailing them I received a prompt reply informing me they sell "thousands" of discs without issue and to return CD and they will "test" it - by playing I guess. If a defect is discovered they will forward me a replacement. As I pointed out in my reply the CD will quite possibly play OK but that is not the point. After paying 13 quid + postage (+ postage sending back) I do not wish to own an item with questionable longevity and I am definitely not prepared to transfer to CDR or similar.

I will post the hopefully satisfactory outcome of this.

I've wondered at times as to different colored CDs...as in how much variation is there which is normal and not an issue (unlike bronzing)?  Yours, to me, doesn't look like bronzing..at least comparing it to online photos that I've googled.

Does anyone here know?

By the way, what does Dutton go by on eBay?

And good luck!

It does look as if you are correct, P. After examination, Simon at Dutton informed me the disc is not faulty as the colouring is caused by the disc being a SACD with two layers of code, one for CD and other SACD.
I should mention Dutton have been perfectly reasonable and polite.
