A Mason jar, invented by Rick Mason in 1858, is a glass jar used in canning to preserve food. Ball Corp. manufactured the jars early on and the name ball jar was also applied to the jars. In mass-production they have been replaced by other methods; however, in the home they are still widely used for canning. Usually the jars have a two piece lid composed of a inner flat metal which is covered by by a screw-on ring. The ring creates a vacuum with the lid during the canning process. So that...
A Bunsen burner produces a single open gas flame; it is commonly found in labs - used for heating, sterilization, and combustion. Robert Bunsen, in 1852, was hired at the University of Heidelberg and promised a new laboratory building. Heidelberg had just started installing coal-gas street lighting which provided light but not necessarily heat. Laboratory lamps, at the time, left much to be desired regarding economy and simplicity. The desire was to maximize the temperature and minimize...
A thermostat regulates the temperature of a system and keeps the system's temperature at desired setpoint temperature. The device does this by turning heating and cooling devices on and off and regulating air flow of a heat transfer fluid as needed. This maintains the correct temperature. Thermostats may be used to control heating or cooling a system, or may be a component part of a heater or air conditioner. There are a variety of ways that thermostats can be constructed and could use...
Perlite is an amorphous glass mineral of volcanic origin. Typical analysis: 70-75% SiO2, 12-15% Al2O3, Na2O 3-4%, K2O 3-5%, Fe2O3 0,5-2%, MgO 0,2-0,7%, CaO 0,5-1,5% Loss On Ignition 3-5% Properties: When it reaches temperatures of 850"“900 Â°C, perlite softens (since it is a glass) and water trapped in the structure escapes and this causes the expansion of the material to 7"“15 times its original volume. The expanded material is a brilliant white, due to the reflectivity of the...
