Aqua slags or swirls?

Having a hard time understanding the difference in colors and slag/swirl patterns.

Swirls, for the most part, a ribbon that meanders inside.  Concentrate really hard and you can follow it.

Slags were mixed, raw materials or glass swirled while molten in the furnace or a tank. You could simulate it with acrylic paint, like Peter Max does with his brush, blending thick colors. Both of yours are slags frozen in time as blended. .

Interesting. Thanks! What makes the colors green/blue-ish in that second one?

When the white striping glass dips below the surface of the transparent colored base glass it can appear to be colored, which color depends on the base glass and how far beneath the surface the white striping glass is.

The bottom photograph is WOW! It looks like a river flowing uphill (backside of marble), going across the surface and then drops as a waterfall into a blue pool.
