| I just found a big zip lock of red & white bricks. The whites are very white,
and there are a couple of waffle plates in there. Are these CA ?

| The bricks might be CA. If they look shiny, more translucent and perhaps warped
they're probably made of CA
The waffle plates however were made from different materials(s)
From Gary Istok's collector guide: LEGO waffle bottom and early circle bottom
plates did not seem to have the same problem of warping that befell the other
LEGO elements. This appears to be due to the fact that the LEGO plates of 1955-63
were made of a composite plastic that contained other plastic materials besides
Cellulose Acetate. This appears to have stopped these 2x8, 4x8, 4x8 curved and
6x8 plates from warping. What that other additive to the Cellulose Acetate is,
has not been revealed by LEGO.

The bricks are shiny, esp the red ones. The white bricks seem brighter than typical
ABS white bricks. The 1x2 bricks (both colors) are without the pin under the
bottom.
I pulled a random 2x4 brick out of the bag, and put it under a magnifying glass/lamp.
Of the eight studs, one has the logo upside-down. Several are pitched a few degrees
out of true, but one is rotated 180-deg. I wonder if that's clue that they
are Samsonite bricks.

At least that one almost certainly is.

Another 1x2 in white, the LEGO logo is so wide, it almost spills off the studs.
The examples here are rather diverse. I also came across a single 1x1 with the
letter 'W' stamped in blue. Looking that up in the catalog, suggests
late 1950s to mid 1960s.

All of these that I've seen have been CA - and they tend to be brittle when
used

Some older CA bricks contained Cadmium which made the bricks having a deeper
color. Especially good seen with red bricks. Obviously because Cadmium is toxic
they had to quit using it.

You can do the "sound test". Drop the pieces on floor tiles. The CA parts have
a brighter sound than the ABS parts.
