The earliest records uncovered that detail the ancient pate de cristal technique of Buy Ketamine Online vases date all the way back to the Mesopotamians of second millennium B.C. Their decorating and jewelry-inlay techniques inform a style still admired to this day.
1. At the start of the process, each potential masterpiece begins as clay or wax model sculpture in the desired shape the vase will take in its final form. (In the days of the Mesopotamians, this was instead a bag of sand or dung.)
2. Then the wax is covered with a mold of plaster or rubber in order to create a replica of the original sculpture. (For the less technologically advanced Mesopotamians, this meant covering the filled bag with threads of glass in its liquid form.)
3. After the plaster dries, the wax is steam until it melts out of the plaster, leaving an empty mold. (For the Mesopotamians, this meant scraping out the bag once the glass dried.)
4. The remaining plaster is then fill with colorful powder glass as paint. Then heated inside a kiln and allowed to cool until it reaches room temperature. (For the Mesopotamians, this meant filling the mold with impure sands in order to bring color to their creations – iron for light greens, magnesium for pinks or violets, sulfur for yellows and dark greens, and silver-free sand or antimony for colorless glass.)
5. At room temperature, the vase is remove from the mold, relieved of any stray glass on its surface. Smoothed of any rough edges, the either polished with abrasive materials for the highest possible sparkle. Or sandblasted for a more frosted or etched decor, and finally ready to showcase.
The Romans, however, introduced a less tediously challenging, and more modern technique. Called glassblowing, more frequently employed by makers of today’s vases. Their technique emerged as a way of developing more sophisticated and ornate crystal. And glass vases ranging from clear glass to colored crystal, decorated by enameling, gliding, or staining techniques. Vases of pure crystal first emerged late in the 15th century, created by Italian glassblowers in Murano who had perfected and protected the technique adopted from the Romans.
