Product Information

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 would not be damaged by chemicals and would be easy to clean. [5] Etymology [ edit ]

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.

Building 25 lies high on the northwestern slope to the northwest of building D in a cluster of apparently contemporaneously used buildings [ 56] (Figs 2 and 3A). It is only slightly rectangular with dimensions of 4.20 m x 3.60 m and walls preserved up to 1 m height. All 12 grinding stones, except a grinding bowl, were found in the middle and upper parts of the fill within roof collapse and wall erosion. The grinding bowl was found on the floor near a wall protrusion made of worked stones, a construction which sometimes replaces pillars in Göbekli Tepe´s buildings [ 56]. Most of the buildings on the northern slope show the same distribution, although their fillings are not similarly well preserved.Turn your Planetary Planetary Micro Mill PULVERISETTE 7 premium line into an analytical measuring system by using the EASY GTM system (Gas Pressure and Temperature Measurement System) with special lid and transmitter as well as a receiver board and the included MillControl software. Your advantage: easy and safe monitoring and analysis of thermal effects, physical and chemical reactions or increases/decreases in pressure through continuous measurement of gas pressure and temperature directly in the grinding bowl.

Two buildings seem to deviate from the pattern observed so far. Building 16 lies north of building D. It has four pillars, walls preserved up to a height of 2 m, measures 3.8 m x 3.6 m and is again part of a cluster of partially contemporary, partially later constructed smaller, up to 2 m long, buildings [ 56] ( Fig 2). 63 grinding stones were found inside the building, together with the small adjacent buildings the number of finds rises to more than 100. The fill shows consecutive layers of erosion and collapse. Grinding stones were found both in the middle and lower parts of the fill; a concentration was observed in the last 50 cm of fill above the floor. A grinding bowl and a stone vessel were found on the floor next to one of the pillars. Almost all types of handstones as well as some blanks for the production of handstones were present. It seems that this building had a special function either regarding grinding or the production of grinding stones, like a workshop. In any case, the massive presence of grinding stones within the last 50 cm of sediments above floor level indicates the long-term specialized use of the building.

The Roman poet Juvenal 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.

In conclusion, we were able to experimentally verify the link between microscopically visible loose agglomerations of short grooves of differing densities and plateaus with U- or V-shaped profiles on the high topography of grinding stones and the processing of cereals as proposed by L. Dubreuil [ 94]. We further observed that the shape and weight of handstones determine the motion and the resulting traces, as they force the worker to adopt certain standardized patterns of movement when grinding material of a certain texture and hardness. The exact replication of shapes and weights of active grinding implements should be considered in further experimental programs for establishing of reference collections. 3D modeling through structure from motion allows a good visualization of the shape and an exact calculation of volumes, which objectify the replication process. As a result, within our sample, assessing the shape and section and macroscopically visible traces can determine the use of grinding equipment in many cases, while microscopic observations support such findings.
