The "type 3" specifically refers to a variation that can have a clear or transparent colored base with a single colored thread.
Type 3 designates a specific pattern within the Veiligglas wirepull series. These marbles have a single, continuous ribbon of opaque glass inside a clear or colorless transparent base.
The single ribbon typically comes in colors like pure white, off-white, yellow, blue, or orange.
Some variations feature a "tapeworm" appearance or a central bubble within the glass.
Key characteristics of a type 4 wirepull
Unconventional Features: They don't conform to the typical single-swirl, double-swirl, or clear-base-with-two-colors patterns of other types.
Hybrid or Blended Glass: The base glass itself can be a combination of different colors or textures.
Multiple Wires: They often have more than one colored wire or other complex wire patterns that don't fit the other categories.
Unique Characteristics: They can have unique features not found in other types, such as special tints or combinations of colors.
Base Glass: All wirepulls share a clear or transparent colored glass base with a single or double wire, though type 4 is a variation on this.
