This is a piece of purple sea/beach glass. This piece is likely from the late 1800’s to 1920’s. It was probably white when manufactured. You see the exposure to the sun and salt causes the chemicals used in the production to turn the glass purple. That means this piece will continue to darken over time. This is for the true purple lover.
Glass measures 1-1/2″ x 1″ Total length of piece is 3-1/4″
