One of the largest issues with treatment on waterlogged wood is finding a way to remove the water in the wood but keep the water that is part of the material. Preventing cell wall collapse (which causes shrinking, cracking, and further damage) of the waterlogged wood while drying is the largest struggle and main goal of treatment.
Glycol and boron solutions are hydrophilic (water-loving) and react with the water in wood, making it unavailable for the fungus. This is why dry rot can seem to be a little stringy; cells grown in drier periods are smaller than the larger, "plumper" cells that grow in Spring, as can be seen in tree rings used to tell how old the tree is.

These lamps burned fish oil or fat trimmings and had wicks of twisted cloth. The Betty lamp differs from earlier oil/grease lamps in that it uses an internal wick holder to eliminate fuel drip common with older lamp ...
Fibre saturation point is a term used in wood mechanics and especially wood drying, to denote the point in the drying process at which only water bound in the cell walls remains - all other water, called free water, having been removed from the cell cavities.

Medullary rays, also known as vascular rays or pith rays, are cellular structures found in some species of wood. They appear as radial planar structures, perpendicular to the growth rings, which are visible to the naked eye. In a transverse section they appear as radiating lines from the centre of the log.
Spirits of turpentine, called camphine, was burned in lamps with glass chimneys in the 1830s through the 1860s. Turpentine blended with grain alcohol was known as burning fluid. Both were used as domestic lamp fuels, gradually replacing whale oil , until kerosene , gas lighting and electric lights began to predominate.
