made on Vistalite was lost on Tivoli. There were also problems with the shells cracking under the pressure of overtightened lugs and exposure to freezing temperatures. The original Vistalite line was phased out due to declining sale and the rising cost of oil-based plastics. Re-issued Vistalite Ludwig reintroduced Vistalite drums in 2001, with the prime seller being a replica of the amber five piece kit played by John Bonham. The re-issue shells are slightly thicker and, in the opinions of some, warmer sounding and more resonant than the originals. The original shells were at a supposed disadvantage due to a noncontinuous bearing edge. The new versions have a continuous 45 degree edge, making what some feel is a fuller, cleaner tone. In 2006, a multitude of drum companies like SONOR (X-Ray), Tama (Starclassic Mirage), RCI International (Starlite), Fibes (Crystallite), ddrum (Diode and Diaton), Zickos, Peace (Echoplasm), and Kirchhoff Schlagwerk (Arctic series) now make acrylic drums thanks to an increase in popularity since 2001. Custom drum companies have also seen growth in demand. Gold n Times acrylic shells are thicker and stronger than '70s vistalites, but are glued and tabbed in the same manner. They are supplied to Ludwig, Tama, and custom drum makers. They are approximately .220 (6mm) thick. Acrylic shells can be glued with adhesives like cyanoacrylates. Modern adhesives are improved over those available in the 1970s. On November 20, 2009, Ray Ducoat, the company’s owner, died. Gold n Times ceased sales although production continued through other outlets. RCI Starlight acrylic shells are "welded" at the seam. The company claims that vibration characteristics of their shells are tested and are superior to glued and tabbed shells. Like the Vistalite, they are factory-equipped with a 45-degree bearing edge. Many of the designs are made to replicate original Vistalite colors and patterns. Quality acrylic shells are also sold to drum parts and custom resellers under the brand "Aquabomb" acrylic shells. This brand name is owed and offered exclusively by Drum Supply House USA . Acrylic shells are welded by applying solvents like di/trichloretheleye to the ends of the acrylic sheet. The sheet is partially dissolved, and when the ends are placed together, the resultant bond is as strong, or stronger than the shell itself. Additionally, the seam is very thin. Gas custom drums of Australia uses sheets of Mitsubishi shinkolite, a high-quality acrylic used in the automotive industry and optics. As
