I doubt the Grangemouth bricks were made from floor sweepings as they would probably
resemble the marbled slotted bricks more if it was the case. Leftovers is much
more probable.

They are said to have used leftover or floor sweeping materials but that may
not have been strictly true, who knows.

I'm trying to sell 3001/2x4 bricks on another site, and I would like to affirm
some information I have provided them with in relation to test bricks.

Please disregard my ignorance, I just need accurate information. I would dislike
providing misleading details to any potential buyer.

Howdy. I've been collecting for a few years now. Love 'em all! Do you
know of Bricklink - it takes a while to become familiar, but if you'd like
to invest some time there, they would happily answer any of your questions.

Mursten, Bayer, BASF, Grangemouth, Wrexham, and other manufacturers were all
contracted by LEGO to produce plastics for their bricks. LEGO provided them with
2x4 molds as test examples.
I'm not sure as to how they all aquired the molds they did, but the Mursten
ABCD bricks are in relation to a clutch test - how firmly they grip to another
piece.' A' being the tightest clutch and 'D' being the loosest.
Due to those test examples LEGO now use the 'C' as the brick of choice.
Modulex is an Architectural scale brick - being an ignorant Aussie, I'm not
familiar with it exactly. They're ultra-cute, that's all I know about
that.
The milky, marbled, and semi-transparent bricks were all produced by the aforementioned
companies because they were pumping coloured plastics into the molds they were
provided with without cleaning the injection pipes before adding another coloured
plastic - in the case of the milky/semi-transparent, they were not adding enough
colour to the mold?
I will do a quick research on prices for you regarding the bricks I've offered
you.

I can tell you that I have never seen a double A, B, C, or D brick being offered
for sale, let alone a complete set. Having said that, does not mean they do not
exist.

If you're not in a rush, I'm happy to get you more information!

The 7xg 1x# is likely a Bayer too although I believe they were made in Italy.
They range in numbers 1-6 and are the only ones with the cross support. They
are effectively a modern 3001.

I've seen Garbanzos 8F transparent neon green brick for sale.
I'm more interested in selling these than buying any.
What about the 7g 3/4 bricks - what's their story?

In Colors, brick.bewdy writes:

Right now, I'm specifically interested in LEGO branded bricks exclusively,
with the exception of unusually sized bricks - Duplo and Modulex sized bricks.
Modulex is so cute though!

Have to agree with Nathan here, post a few pics and just watch who appears.

There are a number of bricks associated with Wrexham too, many of which aren't
that well known and not particularly collected, maybe only one or two of us.

These look like many other standard bricks, nothing unusual, the only one I would
pick out other than the waxy looking bricks are those UK sideways logo bricks.

Samsonite of North America produced these sideways logo bricks too but the mould
markings, studs, logo style, spruce position are different as are the colours
available.

They come in CA and ABS.

I aquired some and listed then for sale on another site.
If you have a link to something that will inform me of exactly what I'm selling,
I really would appreciate that - more than you know.

As for the abcd ones they are more common than the 2xabcd ones and come in all
sorts of colors...there are supposed to be over a thousand shades that bayer
made. The set is very nice. The milky bricks are a bit uncommon and look good.
It is just a mix of color and uncolored plastic and as more coloring is added
it would appear more and more "solid".

Those are nice, 2xabcd large Bayer bricks. There is another set of 2xabcd bricks
with small letters. I am not too familiar with them and only have a handful.

Bayer made the ABCD bricks. They also helped Lego in many other tests and there
are plenty of test bricks from Bayer spanning over about 40 years.

That's old school. Who made the ABCD bricks?

In Colors, Nathan123 writes:

Lego Mursten is referring to the slotted bricks that came after the automatic
binding bricks stage. Early/mid 1950s i think. Mursten translates to "brick".
There were companies that made the slotted bricks under Lego license...GEAS in
Sweden comes to mind.
