designer's own words:Kiddush Glasses (Jewish ritual glass). Material: Aluminum. Variable dimensions. Kiddush is a blessing recited over wine to sanctify the Shabbat, Jewish holiday by a special glass- The Kiddush glass. The dissemination of the known formula of the Kiddush glass into a new, unique and traditional - while modern – new cup, occurs in recognizing the potential that lies in the casting process known as- Angus (the leftover of the metal casting used for the top of the glasses is used to shape the its basis). The fact that you cannot completely control this technique implies that every glass comes out different - each one of a kind.
