Composition
Grain fillers generally consist of three basic components; a binder, a bulking agent and a solvent. The binder is wood finish, and in the case of oil-based fillers is typically a blend of oil and varnish. In the case of water-based fillers, it is acrylic or urethane. The type of binder influences the type of solvent used; oil-based fillers usually use mineral spirits, while water-based fillers use water. Both types of filler use silica as a bulking agent as it resists shrinking and swelling in response to changes in temperature and humidity.

Famous quotes containing the word composition:
“Modern Western thought will pass into history and be incorporated in it, will have its influence and its place, just as our body will pass into the composition of grass, of sheep, of cutlets, and of men. We do not like that kind of immortality, but what is to be done about it?”
—Alexander Herzen (1812–1870)
“The composition of a tragedy requires testicles.”
—Voltaire [François Marie Arouet] (1694–1778)
“If I don’t write to empty my mind, I go mad. As to that regular, uninterrupted love of writing ... I do not understand it. I feel it as a torture, which I must get rid of, but never as a pleasure. On the contrary, I think composition a great pain.”
—George Gordon Noel Byron (1788–1824)
