Possible definitions for foreworn

fireworks
Explosives or combustibles used for display. Of ancient Chinese origin, fireworks evidently developed out of military rockets and explosive missiles, and accompanied the spread of military explosives westward during the European Middle Ages. In force-and-spark compositions, potassium nitrate, sulfur, and ground charcoal are used; additional ingredients produce various types of sparks. In flame compositions, such as the stars that shoot out of rockets, potassium nitrate, salts of antimony, and sulfur may be used; for colored fire, potassium chlorate or perchlorate is combined with a metal salt that determines the color. Rockets are lifted by recoil from the jet of fire thrown out by the burning composition.


formwork
Mold used to form concrete into structural shapes (beams, columns, slabs, shells) for building. Formwork can be of timber, steel, plastic, or fiberglass. The inside surface is coated with a bond breaker (plastic or oil) to keep the concrete from sticking to the mold. Important for high-rise construction is slipforming, whereby a vertical concrete element is continuously cast using a short section of formwork that is repeatedly disassembled and moved upward as each section is finished or that moves slowly and continuously as concrete is being placed. This is sometimes called a climbing form.
