How to Measure a Substance’s Consistency
We face consistency all day long without even thinking about it, for example in the morning when we use toothpaste or face creams. Creams, in particular, have different consistencies. Liquid-like lotions soak into the skin easily – a good example here is sunscreen lotion. More solid-like ointments stick on the skin. This is useful for treating open wounds and cuts, for example. Butter, margarine, cheese, honey and other foods need to be spreadable but not so runny that they drip off the bread or knife.
Another good example in daily life is the bitumen which is used for road construction and roofing. In warm climates, the consistency of soft bitumen can lead to rutting on the road or to bitumen dropping off roof shingles because of insufficient stiffness of the bitumen binder. Very hard bitumen consistency can cause fatigue cracks on the road surface under cold climatic conditions.
