Milk Swirls and Jade

Examples of milk swirls and jade,white streaks through the insulator, the result of foreign matter dissolved in the glass or the presence of certain chemicals in the glass mixture, perhaps introduced through cullet; in some cases there is enough to give the insulator an opaque or jade appearance. Small milk swirls are relatively common and milk swirls dispersed throughout a piece are uncommon. However, jade pieces of Lynchburg, in which the milk is relatively evenly dispersed and the color is opaque, are rare and highly valued by collectors.
