The food-grade material is used in foods, beverages, and cosmetics to keep oils in suspension in water, [ 2 ] and its name may be shortened in the ingredient list as glycerol ester of rosin .
Rosin is added in small quantities to traditional linseed oil/sand gap fillers ("mastic"), used in building work. When mixed with waxes and oils, rosin is the main ingredient of mystic smoke , a gum which, when rubbed and suddenly stretched, appears to produce puffs of smoke from the fingertips.
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 ...

In addition to more conventional fungicides, boron-based fungicide can be supplied in glass-like rods which are inserted into holes drilled into the wood.

Checking: Slight gapping between wood cells that creates a checkerboard-like pattern. Found where wood is cut straight across the grain for carving, such as in a ball-and-claw foot. Dry rot: Decay of seasoned timber caused by fungi that consume the cellulose of wood, leaving a soft skeleton that is readily reduced to powder.
Oleoresins are semi-solid extracts composed of resin and essential or fatty oil, obtained by evaporation of the solvents used for their production. [1] The oleoresin of conifers is known as crude turpentine or gum turpentine , which consists of oil of turpentine and rosin .
Tall oil, also called liquid rosin or tallol, is a viscous yellow-black odorous liquid obtained as a by-product of the kraft process of wood pulp manufacture when pulping mainly coniferous trees. [ 1 ] [ 2 ] The name originated as an anglicization of the Swedish tallolja ('pine oil'). [ 3 ]
