A simple plastic measuring cup, capable of holding the volume one cup. A measuring cup is a kitchen utensil used primarily to measure the volume of liquid or bulk solid cooking ingredients such as flour and sugar, especially for volumes from about 50 mL (approx. 2 fl oz) upwards.
[7] During the 1920s efforts to standardise the dimensions of laboratory glassware began, particularly for ground glass joints, with some manufacturer specific standardisation beginning to occur around this time. Commercial standards began development around 1930, allowing the compatibility of joints between different manufacturers for the ...
To read the volume accurately, the observation must be at an eye level and read at the bottom of a meniscus of the liquid level. [7] The main reason as to why the reading of the volume is done via meniscus is due to the nature of the liquid in a closed surrounded space. By nature, liquid in the cylinder is attracted to the wall around it ...
[7] A 2017 study computed the rate of flow of the medieval glass used in Westminster Abbey from the year 1268. The study found that the room temperature viscosity of this glass was roughly 10 24 Pa · s which is about 10 16 times less viscous than a previous estimate made in 1998, which focused on soda-lime silicate glass.
(A) A low-form or Griffin form beaker (B) A tall-form or Berzelius beaker (C) A flat beaker or crystallizer Philips beaker which can be swirled like a conical flask. Standard or "low-form" (A) beakers typically have a height about 1.4 times the diameter. [3]

The hourglass also found popularity on land as an inexpensive alternative to mechanical clocks. [7] Hourglasses were commonly seen in use in churches, homes, and work places to measure sermons, cooking time, and time spent on breaks from labor. [3] Because they were being used for more everyday tasks, the model of the hourglass began to shrink.
Invented in the late 19th century, its form derives from the fact that all cocktails are traditionally served chilled and contain an aromatic element. Thus, the stem allows the drinker to hold the glass without affecting the temperature of the drink, an important aspect due to the lack of added ice which in other drinks serves to cool the drink, [2] and the wide bowl places the surface of the ...
