open-hearth process
Oceanian (Australasian, Melanesian, Micronesian, and Polynesian) literature developed in isolation from the rest of the world and in a unique geographical environment. This allowed the development of a unique literature to thrive. Oceanian literature was heavily influenced by religion and ritual. This can be seen by the large amount of religious symbolism featured in it. Another major influence in Oceanian society was its intricate oral tradition. For a long time, most Oceanian literature was not written down. As a result, stock formulas and rhyming were used in many works (these traits made it easier to memorize). Gods, creation myths, and spirits are also prominent in Oceanian literature, showcasing again the influence oral tradition had on the literature of Oceania. Modern Oceanian literature is mainly written in the English language but also feature different languages and speech. Literatures of Oceania particularly that of the Pacific have long been isolated from mainstream and traditional movements of literature in the West. The ocean carries a lot of symbolism and meaning to the cultures and people that have travelled through, in which largely has impacted the literary cultures and historical narratives in Oceania.

The open-hearth process is a method of steelmaking in which impure iron is heated in a furnace lined with heat-resisting brick and oxidizing elements are added to produce high-quality steel. This method partially replaced the Bessemer process in the late 19th century and was later replaced by basic oxygen steelmaking. The open-hearth process allowed for the precise control over the composition of metals and resulted in steel with higher purity and consistency.
