, which requires the gentle crushing of sugar, ice, and mint leaves in the glass with a pestle. The invention of mortars and pestles seems related to that of quern-stones, which use a similar principle of naturally indented, durable, hard stone bases and mallets of stone or wood to process food and plant materials, clay, or minerals by stamping, crushing, pulverizing and grinding. A key advantage of the mortar is that it presents a deeper bowl for confining the material to be ground without the waste and spillage that occurs with flat grinding stones. Another advantage is that the mortar can be made large enough for a person to stand upright and adjacent to it and use the combined strength of their upper body and the force of gravity for better stamping. Large mortars allow for several people with several pestles to stamp the material faster and more efficiently. Working over a large mortar that a person can stand next to is physically easier and more ergonomical (by ensuring a better posture of the whole body) than for a small quern, where a person has to crouch and use the uncomfortable, repetitive motion of hand grinding by sliding. Mortars and pestles anticipate modern blenders and grinders and can be described as having the function of small, mobile, hand-operated mills that don't require electricity or fuel to operate. Large wooden mortars and wooden pestles would predate and lead to the invention of butterchurns, as domestication of livestock and use of dairy (during the

) came well after the mortar and pestle. Butter would be churned from cream or milk in a wooden container with a long wooden stick, very like the use of wooden mortars and pestles.


History

Mortars and pestles were invented in the Stone Age, when humans found that processing food and various other materials by grinding and crushing into smaller particles allowed for improved use and various advantages, such as hard grains could be cooked and digested easier if ground first, grog would vastly improve fired clay and larger objects such as blocks of salt would be much easier to handle and use when ground and pulverized into smaller pieces. Various stone mortars and pestles have been found, while wooden or clay ones would perish much easier during the course of time. Scientists have found ancient mortars and pestles in Southwest Asia that date back to approximately 35000 BC. Stone mortars and pestles have also been used by the Kebaran culture (

) from 22000 to 18000 BC to crush grains and other plant material. The Kebaran mortars that have been found are sculpted, slightly conical bowls of porous stone, and the pestles are made of a smoother type of stone. Another Stone Age example are the rock mortars in the

s around 10000 BC to grind cereals for brewing beer in the cavities. These rock mortars are large enough for a person to stand upright by them and crush the cereals inside the cavity with a long wooden pestle. Ancient Africans, Sumerians, Egyptians, Polynesians, Native Americans, Chinese, Indians, Greeks, Celts and countless other people used mortars and pestles for processing materials and substances for cooking, arts, cosmetics, simple chemicals, ceramics and medicine. Since the 14th century, bronze mortars became more popular than stone ones, especially for use in alchemy and early chemistry. Bronze mortars would become more elaborate than stone ones, and had the advantage to be harder, and were easily cast with handles, knobs for handling and spouts for easier pouring. However, the big disadvantage was that bronze would react with acids and other chemicals and corrode easily. Since the late 17th century, glazed porcelain mortars became very useful, since they wouldn't be damaged by chemicals and would be easy to clean.


Etymology

The English word ''mortar'' derives from middle English ''morter'', from old French ''mortier'', from classical
Latin Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the ...
''mortarium'', meaning, among several other usages, "receptacle for pounding" and "product of grinding or pounding"; perhaps related to Sanskrit "mrnati" - to crush, to bruise. The classical Latin ''pistillum'', meaning "pounder", led to English ''pestle''. Stemming from the pistillum, the word

applied both ''mortarium'' and ''pistillum'' to articles used in the preparation of drugs, reflecting the early use of the mortar and pestle as a symbol of a pharmacist or apothecary.

cannon was called "mortar" in French, because the first versions of these cannons looked like big metal mortars of the Medieval Ages and they required to be filled with gunpowder, like a mortar would be full of powdered material.


Mortar and pestle in culture and symbols

The antiquity of the mortar and pestle is well documented in early writing, such as the Egyptian Ebers Papyrus of ~1550 BC (the oldest preserved piece of medical literature) and the
Old Testament The Old Testament (often abbreviated OT) is the first division of the Christian biblical canon, which is based primarily upon the 24 books of the Hebrew Bible or Tanakh, a collection of ancient religious Hebrew writings by the Israelites. The ...
(Numbers 11:8 and Proverbs 27:22). In Indian mythology, Samudra Manthan from Bhagavata Purana creates amrita, the nectar of immortality, by churning the ocean with a pestle. Since medieval times, mortars would be placed or carved on the gravestones of pharmaceuts and doctors. In Russian and Eastern European folklore,
Baba Yaga In Slavic folklore, Baba Yaga, also spelled Baba Jaga (from Polish), is a supernatural being (or one of a trio of sisters of the same name) who appears as a deformed and/or ferocious-looking woman. In fairy tales Baba Yaga flies around in a ...
is described and pictured as flying through the forest standing inside a large wooden mortar (stupa), holding the long wooden pestle in one hand to remove obstacles in front of her, and using the broom in her other hand to sweep and remove her traces behind her. This seems as a trace of some ancient rituals connecting the witch symbols of Baba Yaga with the use of mortars in alchemy, pharmacy and early chemistry, which were all seen as magic by uneducated people in Medieval Ages. Modern pharmacies, especially in Germany, still use mortars and pestles as logos.

. Large wooden mortars and pestles have been used to hull grain in West Africa for centuries. When enslaved Africans were brought to the Americas, they brought this technology—and knowledge of how to use it—with them. During the Middle Passage, some slave ships carried un-hulled rice, and enslaved African women were tasked with using mortars and pestles to prepare it for consumption. In both colonial North and South America, rice continued to be primarily milled by hand in this way until around the mid 1700s when mechanical mills became more widespread.

may interact or mix, contaminating the currently used ingredients. Rough ceramic mortar and pestle sets can be used to reduce substances to very fine powders, but stain easily and are brittle. Porcelain mortars are sometimes conditioned for use by grinding some sand to give them a rougher surface which helps to reduce the particle size. Glass mortars and pestles are fragile, but stain-resistant and suitable for use with liquids. However, they do not grind as finely as the ceramic type. Other materials used include stone, often marble or agate, wood (highly absorbent), bamboo, iron, steel, brass, and

. Mortar and pestle sets made from the wood of old grape vines have proved reliable for grinding salt and pepper at the dinner table. Uncooked rice is sometimes ground in mortars to clean them. This process must be repeated until the rice comes out completely white. Some stones, such as molcajete, need to be seasoned first before use. Metal mortars are kept lightly oiled.


Automatic mortar grinder

Since the results obtained with hand grinding are not easily reproducible, most laboratories use automatic mortar grinders. Grinding time and pressure of the mortar can be adjusted and fixed, saving time and labor. The first automatic Mortar Grinder was invented by F. Kurt Retsch in 1923 and named the "Retschmill" after him.


Advantages

The use of mortar and pestle, pestling, offers the advantage that the substance is crushed with low energy so that the substance will not warm up.
