Glass Bead

Glass gets worked hot around a core and cooled slowly, which separates these from every plated or enameled piece in the family. Color lives inside the material rather than on top of it, so a glass bead cannot wear through, fade at the edges or need replating after ten years of daily wear.

Running down the middle sits a core, a tube usually of sterling silver, which provides the wide bore and keeps glass off the chain. Two failures live in that tube. A merely plated core shows brass at both ends within a couple of years. A core bonded badly to the glass eventually turns inside it. A bead that spins on its own core has a join already coming apart.

Handmade and pressed versions look different once you know where to look. Wound glass shows faint spiral lines and small trapped bubbles, both normal and both evidence of hand work. Pressed glass carries a seam where the mold halves met, which is neither better nor worse and should cost less. Silver and gold foil layers inside are common, adding depth without adding a coating that can rub off.

Weight lands higher than the size suggests, around 3 to 5 grams for a standard bead, so six of them move a bracelet noticeably. Against a cast metal charm, glass is quieter, warmer on skin and far less forgiving of a drop onto tile. Enamel work delivers similar color on a metal body and chips at raised edges instead. Spacers either side of a glass bead are close to essential, since metal on glass is what starts a chip.

Treat these as the fragile pieces in a collection. Take the bracelet off over a bed or a carpet rather than a hard floor. Keep glass out of an ultrasonic tank entirely, because vibration finds the join between glass and core and works it loose. Warm water and a soft cloth handle cleaning. Once a year the ends of the core deserve a look for the yellow tinge that means plating has gone.
