Akro fleshy base colors help me understand

[davesnothere]

Found a few that have a flesh color base cork and a couple patches.

The right is white for comparison. 

The flesh color is translucent and highly reactive.

Was this a color on the older ones , or just the way they came out  on occasion.

Seen one listed as an opal??

The only Akro "Opal" I can think of is a Fire Opal and this isn't one of them. Akro Corkscrews on an off white UV reactive base are not too uncommon. And I think what you have there would be called "lazy corkscrews" as opposed to patches. But more views might alter my thinking on that.

Vintage (and to a large extent, modern) marble making was a relatively crude process.  It was by no means a precision process.  Glass color was affected by a number of factors, including the batch source and mix, what was in the cullet pile , how the furnace was running, how much the pot had cooked, and even the weather.

Awesome thanks guys. Alan that explains some flesh base pelts I have.

I scratched my head when I read  opal in a listing online, some people's kids.
