Thanks so much for your advice. Doesn't have any kind of marks I could find. I first noticed the weight, very heavy. Someone suggested to me that I tap them with a piece of silverware, I did, it gave off a kinda bell sound, don't know if that's reliable, or just some sort of urban legend stuff, lol. Many thanksIf there's any kind of mark on the bottom it'll be easy to ID the maker. If not, I'd start searching patterns on popular mass production glass companies such as Libbey and Anchor Hocking, which generally those markers applied marks, but very often did not. What you have doesn't look like anything in the way of fine cut crystal, such as Waterford, but a set you might find today at a Target or Wal-Mart. Waterford Crystal can be found these at a Costco type outlet, which are not cheaply priced.
...who made this set...assuming it's an ice bucket and highball set...
