Silage gas contains nitric oxide (NO), which will react with oxygen (O 2) in the air to form nitrogen dioxide (NO 2), which is toxic. [16] Lack of oxygen inside the silo can cause asphyxiation. Molds that grow when air reaches cured silage can cause organic dust toxic syndrome. Collapsing silage from large bunker silos has caused deaths. [17]
Anti-climb paint (also known as non-drying paint, anti-intruder paint, anti-vandal grease) is a class of paint consisting of a thick oily coating that is applied with a stiff brush, trowel or by hand using a protective glove. In appearance it is similar to smooth gloss paint when applied but it remains slippery for a minimum of three years ...

A forage harvester – also known as a silage harvester, forager or chopper – is a farm implement that harvests forage plants to make silage. [1] Silage is grass , corn or hay , which has been chopped into small pieces, and compacted together in a storage silo , silage bunker, or in silage bags. [ 2 ]
Fat over lean refers to the principle in oil painting of applying paint with a higher oil to pigment ratio ('fat') over paint with a lower oil to pigment ratio ('lean') to ensure a stable paint film, since it is believed that the paint with the higher oil content remains more flexible.

In oil painting, the simplest form of a glaze is a thin, oily, transparent layer of paint spread over the top of an opaque passage that has been given some time to dry. Light travels through the glaze and is reflected back off of the opaque layer below.
Many Medieval and Renaissance painters used distemper painting rather than oil paint for some of their works. [3] The earliest paintings on canvas were mostly in distemper, which was (and is) also widely used in Asia, especially in Tibetan thankas. Distemper paintings suffer more than oil paintings as they age, and relatively few have survived.
In this way, the paint can be made to dry more quickly (if that is desired), or to have varying levels of gloss. Modern oils paints can, therefore, have complex chemical structures; for example, affecting resistance to UV. By hand, the process involves first mixing the paint pigment with the linseed oil to a crumbly mass on a glass or marble slab.
