Kugels

European Art glass balls for holiday decoration are still commonly referred to in Austria and Germany as Kugels. Kugels range in shape and styles, according to the artist that made them and the season they are displayed. It is quite common to display egg shaped kugels at Easter and Heart shapes at Valentines day. Quality kugels are hand blown or mouth blown art glass. Most are blown into an apple wood mold to retain shape and consistency. Some artists free blow their kugel designs, thus ending up in an irregular shape. Air bubbles are common, and expected by the collector.
