Four Vintage Cordial or Saki Glasses Marking which is difficult to decipher seems to indicate ?Pure Silver? meaning likely 925 or 950 Silver We did a scratch acid test using 18K acid and resulted in a nice blue color indicating silver of 925 or better. Engraved design on each but not exactly the same. Perhaps birds and clouds in the sky? 2.75 inches tall (one is slightly taller) and combined weight of 112 grams. No case - found at a recent estate sale.
