Pressed glass - Beautiful 16 oz apothecary in clear seamless with attached flat lids and are manufactured using time-tested machine blowing and I.S. pressing methods. All the glass containers are specially designed to withstand the heat from burning candles.
Please note we are now carrying the Pressed version of this jar - which is heavier than our old Seamless version. We have found this ships better and is a more "substantial" jar.
