After achieving the desired shape, the glassblower cools the molten glass object down.Stage 3: an experienced artisan decorates the glass items using various decorative techniques. Depending on the desired result, the item is sandblasted and/or engraved and a Swarovski crystal element is carefully attached in a designated place to create a unique glassware product.
