Here, is the green mass of the wood, is its oven dry mass (the attainment of constant mass generally after drying in an oven set at 103 ± 2 °C (218 ± 4 °F) for 24 hours as mentioned by Walker et al., 1993). The equation can also be expressed as a fraction of the mass of the water and the mass of the oven dry wood rather than a percentage.
Spackling paste or spackle is a putty used to fill holes, small cracks, and other minor surface defects in wood, drywall, and plaster. [ 1 ] [ 2 ] Typically, spackling is composed of gypsum plaster from hydrated calcium sulfate and glue .

Earthen plasters are becoming more popular in interior design due to its sustainable and eco-friendly characteristics. The plaster influences the thermal comfort, the indoor air quality and energy efficiency in a positive way. During the drying process however, there is shrinkage which affects its ability to adhere properly to the surface. [3 ...
A crack or cracks propagating from near the edge of the log towards the centre, usually along the line of the medullary rays, causing the wood to shrink more at right angles to the medullary rays than along them, causing warping of anything made from the wood. The cause is often rapid or uneven seasoning, causing the outside of the log to ...
Crack formation during drying depends strongly on adhesion to the sublayer, paint film thickness, composition, and the mechanical properties of the sublayer. [2] Craquelure formed during the drying process appears within days of painting and is characterized by shallow cracks that are localized to the topmost layers of paint.
The plaster is not pure plaster of Paris, but rather has additives to improve green strength, dry strength, permeability, and castability.For instance, talc or magnesium oxide are added to prevent cracking and reduce setting time; lime and cement limit expansion during baking; glass fibers increase strength; sand can be used as a filler.
