Quasi-solid is the physical term for a semi-solid. While similar to a solid in some respects (it can support its own weight and hold its shape), a quasi-solid also shares some properties of liquids, such as shape conformity to something applying pressure to it, or the ability to flow under pressure. Quasi-solids are also known as amorphous solids because at the microscopic scale they are disordered, unlike traditional crystalline solids. For instance, common Glass is a semi-solid, because on the molecular level, its units, aligned in the crystal lattice, are octagonal in structure. When octagons are tiled together in the lattice, their eight-sided geometry forces spaces to be formed between units, which is the cause for Glass' existence as a quasi-solid.
