Thermally modified wood is engineered wood that has been modified by a controlled pyrolysis process of wood being heated to (> 180 °C) in an oxygen free atmosphere. This process changes to the chemical structures of wood's cell wall components lignin , cellulose and hemicellulose which decreases its hygroscopy and thus increases dimensional ...
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.
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 ...
Calf suet. Suet is the raw, hard fat of beef, lamb or mutton found around the loins and kidneys.. Suet has a melting point of between 45 and 50 °C (113 and 122 °F) and congelation between 37 and 40 °C (99 and 104 °F).
Tallow made by rendering calf suet. Tallow is a rendered form of beef or mutton suet, primarily made up of triglycerides. In industry, tallow is not strictly defined as beef or mutton suet. In this context, tallow is animal fat that conforms to certain technical criteria, including its melting point.
Stucco or render is a construction material made of aggregates, a binder, and water. Stucco is applied wet and hardens to a very dense solid. Stucco is applied wet and hardens to a very dense solid. It is used as a decorative coating for walls and ceilings, exterior walls, and as a sculptural and artistic material in architecture.
High Humidity reduces mechanical damage such as brittle paint but raises the risks of biological organisms, e.g. white efflorescence and green-to-black stains on a panel painting. [12] High Humidity also raises the risks of curving or warping of the wood over time, forcing the paint to flake off.
Cement render or cement plaster is the application of a mortar mix of sand and cement, (optionally lime) and water to brick, concrete, stone, or mud brick. It is often textured, colored, or painted after application.
