Rendering is a process that converts waste animal tissue into stable, usable materials. Rendering can refer to any processing of animal products into more useful materials, or, more narrowly, to the rendering of whole animal fatty tissue into purified fats like lard or tallow. Rendering can be carried out on an industrial, farm, or kitchen scale.
Tallow after rendering. The primary use of suet is to make tallow, although it is also used as an ingredient in cooking, especially in traditional baked puddings, such as British Christmas pudding. Suet is made into tallow in a process called rendering, which involves melting fats and extended simmering, followed by straining, then cooling. The ...
Commercial tallow commonly contains fat derived from other animals, such as lard from pigs, or even from plant sources. Tallow consists mainly of triglycerides (fat), whose major constituents are derived from stearic and oleic acids. The solid material remaining after rendering is called cracklings, greaves, or graves. [1] It has been used ...
In wet rendering, pig fat is boiled in water or steamed at a high temperature and the lard, which is insoluble in water, is skimmed from the surface of the mixture or separated in an industrial centrifuge. In dry rendering, the fat is exposed to high heat in a pan or oven without water (a process similar to frying bacon).
Rendering is a traditional craft that has evolved over many centuries. Basic rendering began as a method of excluding draughts and rain by using clay to fill in cracks and crevices, referred to as wattle-and-daub. [1] Other renders, based on lime [2] binders were also used over the years. These materials had one significant disadvantage in that ...
Enamel paint is paint that air-dries to a hard, usually glossy, finish, used for coating surfaces that are outdoors or otherwise subject to hard wear or variations in temperature; it should not be confused with decorated objects in "painted enamel", where vitreous enamel is applied with brushes and fired in a kiln. The name is something of a ...
Killing your entire lawn gets rid of everything—grassy and broadleaf weeds, off-type lawn grasses, and the few strands of good grass you have left. Unlike the five percent household vinegar used ...
Low-VOC paint types include latex (water-based), recycled latex (water-based), acrylic, and milk paint. [1] [2] The labels of paint cans can be checked for the following information: To be considered low-VOC, the paint should contain <50 g/L of VOC. [citation needed] To be considered zero-VOC, the paint should contain <5 g/L of VOC. [citation ...
