Bakelite, materials known as SRBF, SRBP & SRBG or Synthetic Resin BondedFabric, Paper or Glass materials. Bakelite is a brand-name material developed in 1909 by Dr. Leo Baekeland. In 1939, the companies were acquired by Union Carbide and Carbon Corporation. Thermosetting resins such as Bakelite required heat and pressure during the molding cycle, but could be removed from the molding process without being cooled, again making the molding process faster. Baekeland's initial intent was to find a replacement for shellac, a material in limited supply because it was made naturally from the excretion of lac insects (specifically Kerria lacca). Phenolic sheet is a hard, dense material made by applying heat and pressure to layers of paper or glass cloth impregnated with synthetic resin. [11]:172–174 Blocks or rods of cast resin, also known as "artificial amber", were machined and carved to create items such as pipe stems, cigarette holders and jewelry. which means many units (parts).
