Color Swirls

Examples of color swirls, streaks or swirls of color different than the primary color of the insulator, usually the result of inadequate mixing of cullet (recycled glass) added to the glass batch or dissolved foreign material in the glass mixture. The most common are green or amber swirls in aqua. Small amber swirls are often caused by iron oxide (rust) from ladles or other tools used to handle the glass. Color swirls often occur in bi-color pieces. These are not rare in Lynchburgs, although pieces with large or pronounced swirls are highly valued by collectors.
