Using the Empirical Method to Identify ALLEY Blue Swirls

[Plutonianfire]

As per the previous thread on using an empirical approach to identify the maker of a blue swirl, it was noted that ALLEY made blue swirls with thick, bright blue swirl lines that tended to end in the middle of nowhere on a white base. The two photos below are known ALLEY marbles from the Joe Marble web site linked to Marble Connection. Each marble shows thick, bright blue swirl lines that tend to end in a sea of white on the marble base.

Using the criterion of blue swirls with thick, bright blue swirl lines that tend to end in a sea of white, the photos below are for two marbles in my collection that meet the ALLEY criterion.

I would agree with Alley on this cobalt blue swirl.

I would agree with later Alley on that. Not because of the blue but because of some tendencies of the glass that I can see Alley in. But that second photo from the Joemarbles site is identical to some that Ravenswood made. In pattern, size, and glass.
