Marble King "Tune-up" Swirl
Marble King · Early 1950s (St. Marys Era)
Identification summary
The 'Tune-up' swirl is a transitional glass marble produced by Marble King during the early 1950s. Unlike the structured patch-and-ribbon patterns the company is known for, these marbles feature erratic, swirling ribbons of color. They were typically produced during machine setup or 'tune-up' phases when the glass flow was not yet stabilized to form distinct ribbons. They are highly prized by specialized Marble King collectors for their unique, non-standard appearance.
