| Hello,
So I am well aware of the "sun burnt" effect on white, blues, yellows, the old
light grays and among other colors, however I am sorting through quite a bit
of used Lego with the old light grays and I pulled quite a bit of them out believing
they were discolored by the sun. Upon closer inspection, they appear to be quite
uniform in their color, including underneath, just definitely a different shade
than the others and not quite like the "sun burnt" ones. Does anyone else out
there recall issues with Lego having off color batches on old light grays in
the past like they have trouble with now on the new light bluish grays and yellows?
Thanks in advance for everyone's time.
Sincerely,
Ken

| Not aware of any problems or lack thereof but have noticed similar shades myself.

| So what do you do with them? Do you list them separately and describe them accordingly
with color variation? They are definitely more "yellow" than the typical old
light gray but they are not the sun burnt yellow and as mentioned, they are uniform
all over, including underneath. These are good clean pieces with little to no
wear and I hate the idea of discarding them thinking they are "bad".
Now I wonder how much of my old personal collection may have this with the old
light grays? That will take time to go through.

| Only just started to list my light grey items so I've still to decide what
to do with variations other than those I consider yellowed which will have that
note attached.
I have several thousand parts in light grey to sort and list so I will have to
think about this carefully.
Takes an absolute age, good light and examples of lbg parts to sort them, going
to be a mammoth task.

the responses. Take care.

| I'm not sure that it's only the sun light in itself that causes discoloration.
In my old store inventory, I've found a small number of parts that were
fully discolored, yet they were not exposed to direct sun light.
On the other hand, I had the little Filmore VW bus (from Cars) in which certain
colors on one side became discolored.

| Fully discolored as in uniform all around including underneath? I wondered if
pieces become discolored from other reasons other than direct sunlight. Any ideas
what causes this? From your scenario, it almost sounds like "batch" issues as
some in storage discolored while others did not.

There’s one reason for discolaration: degradation.
(And plastics degrade differently depending on their compositions, as we all
know because we all heard about the pre-2004 fire retardants that are often incriminated.)
But there are several reasons for degradation: UV, humidity, temperature, and
undoubtedly others.
The UV to which LEGO pieces are exposed generally come from the sunlight. And
as they are light, by definition they don’t hit in the shadow. So their effects,
besides being strong on some plastics, are easily noticed.
As for your parts, they may be from different batches. But their difference
in colour might not have been noticeable when they were brand new. They might
also have aged differently because of their composition. Or they may be like
other bricks in composition but still have aged differently because they weren’t
stored like others.

We have wondered about the opacity and density of the different batch productions
over the years as we have put together multiple sets from 80's through 2000.
There seems to be an altogether different feel from 5 years to the next (due
to composition changes?) in a lot of the bricks in reclaimed set batches we have
handled recently. Ours were stored in 70 to 78 degree F in a Lego case and Lego
trunk for years- thus, no UV effects.
Separately, I have acquired two new building sets and just "feel" a different
lightness and lack of opaque color...
Separately- Really wanting these variations in the old light gray to not be "donated"
but exposed for whatever variant in color or production made these happen at
whatever time sets had these colour variants!!!

| Something thing I've read about is oxidation of the plastic over time. There
was a guy out there with a tutorial on how to un-yellow white bricks with baking
soda. If I find a link I'll post it later. That's a possible explanation.
Nicotine is also notorious for discoloring plastic. It gives a slightly greener
hue than sun damage, typically. The uniformity here is the curious thing, and
it's driven me nuts a few times as I move a lot of old parts. One thing that
has occurred to me is that it might have to do with the production run or
facility like we see with Pearl Gold. In that case its gotten to the point where
a category for Dark Pearl Gold had to be added even though it was never officially
a Lego color. If we could pin down the cause perhaps it would be worth adding
such a subcategory for "yellowish light gray"?
When I find so discolored bricks that I cannot reconcile them with the rest of
the Light gray, as such, I tend to put them in the reject pile to be reconsidered
at a later date. That is, unless it is so rare of a part that I just don't
feel right taking it out of circulation. In that case I just make a note and
bargain-price it. I find, when you're talking about old parts, the typical
customer is of the sort who'd understand that 30+ year old parts just won't
be perfect and will still buy so long as you're honest and fair.

| That is what I am in the long process of doing right now with the sorting. Sounds
like I either "donate" them or list them accordingly when I get to that point.
My other idea is to simply put all these "rejects" into a giant tub for any little
ones to come over so they can mess around with them instead of wanting to mess
around in my new inventory.
I tried to "un-yellow" some whites with moderate success using the Oxi-clean/hydrogen
peroxide mix in the sun. I am afraid over time though they seem to simply revert
back to being discolored. A small batch of whites I tried it on and the some
white pieces from one of my old sets were nice again afterward but now seeing
after a couple years again, they don't look so good as I recall.

Another option for you may be to just list it as a custom item in your store,
a bulk lot of light gray bricks.
I'd actually be interested in some photos to see what you're talking
about, since I am having a hard time understanding the differences from the description.

I have seen 2 different shades of Light Gray and not all of it is yellowing or
age but could be. Occasionally if I have a lot of the off color I will list
with a note but unless it is a piece I want I usually put them in the donate
pile.

I'm having the same problem. I most often see this issue with part ,
technic pins and gears. Example image attached (about 50% of all parts 3651 are
"yellowish").
