For pharmaceutical use, the mortar and the head of the pestle are usually made of porcelain, while the handle of the pestle is made of wood. This is known as a Wedgwood mortar and pestle and originated in 1759. Today the act of mixing ingredients or reducing the particle size is known as trituration.

Planetary Micro Mill PULVERISETTE 7 premium line / Description Planetary Micro Mill PULVERISETTE 7 premium line / Description

Reliable, proven performer – Essa Pulverising Mill Bowls were pioneered in the 1980’s and are proven performers that are widely used by laboratories and global exploration and mining companies across the world. They are constructed from carefully-selected steel in a range of sizes and significantly minimise the risk of sample contamination. I know this might seem like overkill, but you can thank me when you’re breathing easy many years from now. 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.

Alcoholic beverages are another important aspect of feasts [ 119, 120], and producing them is an important use of cereals. Tentative evidence for the consumption of alcohol at Göbekli Tepe has been published [ 51]. Consumption during feasts may be associated with special serving paraphernalia [ 120]. Göbekli Tepe has produced around 80 sherds of stone drinking vessels [ 72]. The vessels are thin-walled and made in part of varieties of ‘greenstone’. About half of the fragments were decorated. Stone vessel fragments appear in all strata at Göbekli Tepe; some have marks of repair (holes to fit fragments together) and some sherds were reused as ‘shaft straighteners’. Both likely indicate the high value of the raw material. These bowls are available in a range of sizes including the 800, 1000, 2000 and 5000 cc nominal capacities.

Acknowledgments

Besides food and drink, Twiss identifies a special physical setting, ritual / performance and commemoration as key indicators to prove feasting in the archaeological record [ 120]. As has been discussed in detail elsewhere, many of these indicators fit the evidence from Göbekli Tepe [ 51, 72, 73, 116]. At Göbekli Tepe, the non-domestic monumental buildings with their benches hint at a gathering of some sort, while ritual and performance inside or near these buildings are highlighted by evidence in the form of several miniature stone masks, suggesting masquerade [ 121]. We assume that the stone masks are miniature representations of real organic masks actually worn, as there are further hints towards the importance of masquerade. It was remarked early on that crane depictions at Göbekli Tepe feature human legs–whereas the anatomy of other birds is depicted correctly–and therefore might indeed indicate masked humans [ 64]. This bowl is ideal for low-level multi-element analysis sample preparation and is used when environmental and metallurgic analyses are required. It is particularly useful in cases where low contaminant levels are required when preparing samples for further testing. This integrated scientific archaeological approach has for the first time produced a basis for assessing the role of cereals at Göbekli Tepe. The massive presence of grinding equipment and standardization in the production and use of handstones hint at large-scale cereal processing in layer II. This is supported by use-wear traces and the presence of phytoliths in samples from their surfaces. Twiss PC, Suess E, Smith RM. Morphological classification of grass phytoliths.
