Gallium highly reactive (rubidium and caesium) nor highly toxic (mercury) and can therefore be used in metal-in-glass high-temperature thermometers. It is also notable for having one of the largest liquid ranges for a metal, and for having (unlike mercury) a low vapor pressure at high temperatures. Gallium's boiling point, 2673 K, is more than eight times higher than its melting point on the absolute scale, the greatest ratio between melting point and boiling point of any element. Unlike mercury, liquid gallium metal wets glass and skin, along with most other materials (with the exceptions of quartz, graphite, and Teflon), making it
Food safety-risk analysis review and editing by food safety and science communities. A proper risk assessment is a constantly revolving process consisting of the following steps: (i) hazard identification, (ii) hazard characterization, (iii) exposure assessment, and (iv) risk characterization. "The identification of biological, chemical, and physical agents capable of causing adverse health effects and which may be present in a particular food or group of foods." This is often considered the most important step in a risk assessment as an unidentified hazard in the early stages of the production process can cause devastating effects in later stages. "The qualitative and/or quantitative evaluation of
