No need to apologise.-
This is a new term for me, but I know this swirled slip effect and have several necklaces of threaded agateware bead elements, such as the outer necklace shown on page 103 in my book "Beads!" :
The glazed swirled coloured slip discs shown there each have 4 holes and were designed to be threaded together in a particular way, with 2 matching "End Spacers" that draw the 2 parallel strands together to one, and a cylindrical bead used as a toggle at one end with a loop for it at the other.

My impression of the lampwork glass beads under discussion here is that the 2-colour swirling is very controlled and gives a rather regular spiral at intervals around the girth of the bead. The "Scroddled" ceramic items are more like randomly scrambled.

Obviously the ceramic material even when rather liquid behaves differently from molten glass, but both give a stirred or swirled look
that can be decorative.

You use the term for glass marbles. Is it generally accepted in the marble-collecting world?
