Acetone-Rosin Treatment is sometimes used on dense wood that cannot be penetrated by PEG. [13] This would include softwoods that are nonporous. The goal of this treatment is to replace cells of wood with natural rosin. Rosin is a natural resin that is produced within some woods, for example pines naturally produce resin and are considered a ...

Harris Water Treatment Plant in Toronto, Ontario, Canada, is both a crucial piece of infrastructure and an architecturally acclaimed historic building named after the longtime commissioner of Toronto's public works Roland Caldwell Harris.
Curing is any of various food preservation and flavoring processes of foods such as meat, fish and vegetables, by the addition of salt, with the aim of drawing moisture out of the food by the process of osmosis. Because curing increases the solute concentration in the food and hence decreases its water potential, the food becomes inhospitable ...
Mockup. In manufacturing and design, a mockup, or mock-up, is a scale or full-size model of a design or device, used for teaching, demonstration, design evaluation, promotion, and other purposes. A mockup may be a prototype if it provides at least part of the functionality of a system and enables testing of a design. [1]
Wood treated with this process is often used for cladding or siding, flooring, furniture and windows. For the control of pests that may be harbored in wood packaging material (i.e. crates and pallets), the ISPM 15 requires heat treatment of wood to 56 °C for 30 minutes to receive the HT stamp.
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 ...
The mock-up serves as both an aesthetic review, but also provides the contractors the opportunity to field test the assembly before full-scale assembly. The mock up may be required to be tested for water tightness and lateral forces. The mock-up panel might be 10 feet wide by 12 feet high, showing the full wall span from floor to floor.
Because of its properties that prevent water absorption, combined with its lack of flavor and odor, food grade mineral oil is a popular preservative for wooden cutting boards, salad bowls, and utensils. Periodically rubbing a small amount of mineral oil into a wooden kitchen item impedes absorption of food liquids, and thereby food odors ...
