Cornish tin-streamers and the Australian gold rush: technology transfer in alluvial mining

Abstract

The Cornish are known around the world for their mining skills. In the 19th century the migration of Cornish mining families created a diasporic community with settlements in the United States, Mexico, South Africa and Australia centred on copper, tin and gold mines. While the Cornish are generally associated with underground mining, recent research in Australia suggests that ancient methods for working surface tin deposits played an important role during the gold rush. The identification of Cornish tin-streaming as the source of alluvial mining technology in Australia sheds light on a little-documented branch of mining that has played a significant role in shaping the landscape of goldfields regions.     

Excavations on the Site of the Tudor Manor House at Micheldever,Hampshire

Abstract

Trial excavations prior to building development on the site of Thomas Wriothesley’s important manor house built about 1537 suggest a continuous succession of large houses on the site from the 14th century to the 18th. The earliest structures may represent a country retreat for the Abbots of Hyde.     

Seventeenth-century Pottery from Ash,Surrey

Abstract

About 2,000 sherds, mainly in white fabric, were found on a site at Ash which was one of several producing similar wares on the West Surrey and Hampshire borders. Some of the sherds were medieval, but the remainder were 17th century and are analysed in an attempt to assess the forms and characteristics of the post-medieval pottery made at Ash. Documentary evidence discloses the presence of potters in Ash in the 17th and 18th centuries, although there is no direct link with the site, and also indicates possible sources for the potters’ clay.     

Investigating absence: Assessing the cumulative effects of casual collecting at a 19th century Bahamian plantation

Abstract

Recent archaeological work at Prospect Hill, a 19th century plantation in the Bahamas, revealed artifact patterns that are inconsistent with expectations for a plantation site. The quantity and quality of artifacts in residential areas associated with the planter family and the enslaved population were inverted and suggest significant post abandonment changes. The site of Prospect Hill has been a destination for tourists and student groups since the mid-20th century, and the areas of the site most accessible to these visitors are also those with surprisingly low artifact counts. I investigated the possibility that regular visitation involved casual collecting using historical data as well as artifact assemblages from archaeological work at Prospect Hill. My analysis suggests that the archaeological record has been altered significantly through casual, opportunistic collecting, and it offers insights for identifying casual collecting elsewhere.     

Observations on the Ancient City Walls of Rochester

Abstract

A recent survey of the floor-tiles of Cleeve Abbey has revealed a much larger range of designs and fabric groups than had previously been assumed. The style of the earliest pavements derive from those laid at Clarendon Palace in the first half of the 13th century, and may have been made on site. In the late 13th century tiles of high quality were imported from the Gloucester region to pave the frater. The next group of tiles came from a Somerset tilery operating at the same time or just after the Gloucestershire tilery. By c. 1330 the entire church was paved along with the sacristy and chapterhouse, using tiles made by a local industry. There was no revival of tile-making after the mid-14th century.     

A Buff Coat of circa 1645

Abstract

Rescue excavations on part of the site of Richmond Palace, Surrey (NGR, TQ174748), revealed a revetment wall, part of a large moat, and other structures; the finds indicate a construction date in the first half of the 17th century, during a rebuilding of the Palace outworks.     

Polesworth: a north Warwickshire country pottery

Abstract

In 1986 excavations for house foundations at Polesworth in northern Warwickshire (SK 263 980) uncovered a pottery waster dump. Fine wares, lead glazed and unglazed coarsewares, including a number a horticultural vessels, were recovered, together with kiln furniture. An archaeological excavation adjacent to the construction site revealed stratigraphy relating to the backfilling of a clay pit with potting waste early in the 18th century. Documentary and other evidence shows that the pottery was in production from the late 17th to early 19th centuries.     

Eighteenth-century glass and pottery manufacture at Morison’s Haven,Prestongrange, East Lothian

Abstract

This paper presents the results of archaeological investigations of the remains of an 18th-century glassworks at Prestongrange Museum, near Prestonpans, East Lothian. The site is part of an industrial complex previously known as Morison’s Haven, named after its associated tidal harbour. It has a long history of coal extraction that was established as early as the 13th century, and includes industries such as glassmaking, salt, pottery and brick and tile manufacture, and a colliery. The archaeological remains of the glassworks came to light during investigative works designed to locate Gordon’s Pottery, which was known to have manufactured fine tablewares in the 18th century.     

DISCOVERY,PRODUCTION AND USE OF TIN‐BASED OPACIFIERS IN GLASSES,ENAMELS AND GLAZES FROM THE LATE IRON AGE ONWARDS: A REASSESSMENT*

Tin‐based opacifiers (lead stannate yellow and tin oxide white) were first used in glass production for a short period in Europe from the second to the first centuries bc , and then again throughout the Roman and Byzantine Empires from the fourth century ad onwards. Tin oxide was also used in the production of Islamic opaque glazes from the ninth century ad , and subsequently in enamels applied to Islamic and Venetian glasses from the 12th century ad onwards. A selection of published analytical data for the tin‐opacified glasses, enamels and glazes is summarized, and the methods used in their production are reassessed. The phase transformations occurring when mixtures of lead oxide, tin oxide and silica are fired are investigated with high temperature X‐ray diffraction (XRD) using a synchrotron radiation source, and these results are used to explain the observed differences in the glass, enamel and glaze compositions. Possible reasons for the use of tin‐based opacifiers in the second to first centuries bc , and for the switch from antimony‐ to tin‐based opacifiers in the fourth century ad are suggested, and the possible contexts in which tin‐based opacifiers might have been discovered are considered. The introduction of tin‐opacified glazes by Islamic potters in the ninth century ad is discussed in terms of technological transfer or independent invention.     

A STUDY ON LATE MEDIEVAL TRANSPARENT‐GLAZED POTTERY AND ARCHAIC MAJOLICA FROM ORVIETO (CENTRAL ITALY)*

Nineteen samples of medieval transparent‐glazed pottery and archaic majolica from Orvieto (central Italy) were studied. They were classified by archaeological criterion as follows: five transparent‐glazed fragments with green and brown decorations (first half of the 13th century), eight green transparent‐glazed fragments (13th century) and six tin‐glazed fragments with green and brown decorations (second half of the 13th century). SEM–EDX, XRD (the Rietveld method) and XRF were used to characterize the chemical and mineralogical compositions both of the bodies and the coatings. In all of the samples, the paste is Ca‐rich with CaO contents as high as 13–20 wt%. The mineralogical composition is compatible with a firing temperature of about 950°C, which is the typical temperature reached in a wood kiln. No difference was observed between the bodies of transparent‐ and tin‐glazed pottery. In the case of transparent glazes, the burial conditions lead to heavy weathering of the samples. However, on the basis of the analyses carried out in non‐weathered areas, the typical composition is PbO 55–65 wt%, SiO₂31–35 wt%. In tin glazes, the tin is scattered on the mass of the glaze as SnO₂crystals with a concentration of 7–14 wt%. Concerning the decorations, it is established that the green colour is due to the presence of copper, while manganese is responsible for the brown colour. These pigments, which represent the typical colours of ‘archaic majolica’, are spread through the glaze homogeneously, apart from one case in which there is clear evidence of manganese oxide crystals.     

Nash Mills—The Endless Web Revisited

Abstract

A watermill is known to have existed on the river Gade since the 11th century on the site of Nash Mills, Hertfordshire, where a purpose-built paper mill was constructed in the late 18th century. In 1810 the mill was purchased by John Dickinson, one of the great innovators of the paper industry. The mill evolved significantly during the 19th and early 20th centuries as part of Dickinson's expanding business, which at one stage comprised five mills in the locality. Nash Mills remained in the ownership of John Dickinson and his successors until 1990, ceasing production in 2006, the last of Dickinson's mills to do so. Using documentary and building evidence, this article examines the development of the mill, emphasising the relationships between personalities, events, structures, processes, and changing business and technological influences.     

Platform cache encampments: Implications for mobility strategies and the earliest ancestral Apaches

Abstract

The Hormiguero site is a large mountainside Apache residential site in the Peloncillo Mountains of southern Arizona that lies in the heart of historically documented Chiricahua Apache territory. It represents an encampment at an important caching location, a category of residential site that has not been previously described archaeologically. Ethnographic data are enlisted to understand this unique type of Apache residential site and a previously unknown cache form—the platform cache. Archaeological evidence is combined from a number of sites with caches like those at Hormiguero to interpret aspects of cultural identity and chronology including the presence of ancestral Apaches in southern Arizona as early as the 14th century a.d.     

A Survey of Shipwreck Sites Off the Southwestern Coast of Turkey

Abstract

Using a combination of remote sensing techniques (side-scan sonar and underwater television), and visual inspection by SCUBA-diving, 18 wrecks ranging in age from preclassical to 19th century A.C. were located between Bodrum and Cape Gelidonya. The majority of wreck sites were known to local sponge divers. All except one site have been looted; nevertheless, eight sites are judged worthy of further investigation.     

Excavation of a pit at 16 Tunsgate,Guildford, Surrey, 1991

Abstract

The site lies to the south of the High Street in Guildford’s town centre, SU 9980 4944. The pit yielded a large assemblage of artefacts. The significance of the assemblage lies in its size and its coherence as a single, chronologically uncontaminated and sealed deposit. The finds form a discrete group of ceramics, glass, clay pipes and organic remains dating from c.1650-1714, and deposited c.1702-14. Many of the vessels after reconstruction proved to be complete, or almost so. Because of the location of the site in Tunsgate, the artefacts must either have come from the Tun Inn, which had a frontage on the High Street, or from a property nearby belonging to the owner of the Tun Inn. The end of the 17th century and the beginning of the 18th century is a particularly interesting period for ceramic and glass studies and the finds from 16 Tunsgate reflect this. The assemblage contains previously unknown examples of the work of John Dwight and George Ravenscroft, a soda glass with a hitherto unknown type of seal, the largest group of mould-blown cristallo beakers so far found in the United Kingdom or North America and a unique group of animal remains that provide a snapshot of inn food in the early 18th century. The finds are on display in Guildford Museum.     

Excavations at Houndhill,near Barnsley,Yorkshire

Abstract

A ‘cottage’ weaving industry was established at Houndhill, family seat of the Elmhirsts in Worsbrough, near Barnsley, during the mid-16th century. It ceased early in the 17th century but excavation has shown it was revived under new ownership in the late 18th century. During the 19th century the mill became a general farm store and was totally demolished in the 1930s to permit a garden extension. The excavation was planned to retain any remaining features for conservation as part of the historical interest of the residence.¹     

Excavations at Rockley Smithies,a water-powered bloomery of the 16th and 17th Centuries

Abstract

Between about 1500 and 1640 iron was smelted by the direct, bloomery, process on the lands of the Rockley family at (N.G.R.) SE/340023, to the south-west of Barnsley, Yorkshire, using charcoal and ore from the well-wooded outcrops of the Tankersley ironstone, adjacent to the site. Evidence for operation early in the 16th century was limited to accumulations of hearth-cinder and of debris from ore-roasting, minor structures and traces of a dam. About 1600 a major rebuilding involved the construction of a bloom-hearth and probably two stringhearths, with bellows powered by waterwheels, and an unpowered hammer. Minor rebuilding took place early in the 17th century, and archaeological and documentary evidence combine to place abandonment at about 1640. Demolition and stone-robbing could well have provided material for the blast-furnace built a short distance away in 1652. The bloomery site was abandoned to pasture and perhaps a cottage, and at some time early in the 19th century was occupied by two houses and a workshop for an adjacent colliery tramway. It was covered by a road embankment in 1966.

Evidence was found of techniques at a comparatively advanced bloomery, in operation at a time when English ironmasters were, however, increasingly favouring the use of the blast furnace.     

Galilee Blooming: First palynological and archaeological data from an Early Byzantine Cistern at Horvat Kur

Abstract

Preliminary archaeological and palynological results are presented from an early Byzantine cistern of the village Horvat Kur in eastern Lower Galilee/Israel. The rural site was settled from the Hellenistic until the Early Arab period, its synagogue was constructed shortly after 425 AD and renovated sometimes during the 2nd half of the 6th century AD. It was abandoned probably as a consequence of the earthquake of 749 AD. The intact and properly sealed cistern contained complete or fully restorable pottery. Two cooking pots from the early 5th century AD comprised sediments which was sampled for palynological purposes. Both samples, as well as a sample from the soil beneath one of the pots and a modern surface sample from the site, revealed well preserved palynomorphs in comparably high concentration showing a great potential of the cistern as a pollen archive. The pollen content points to an open, grassy semiarid landscape with an apparent scarcity of cultivars and trees in the vicinity of the site and an abundance of herbs, especially Asteraceae, which are still commonly found in modern regional vegetation.     

Two Occurrences of Weser Slipware from Early 17th Century Iroquois Sites in New York State

Abstract

Examples of Weser Slipware, recently recovered from two Iroquois sites in New York State, provide evidence for the intensification of Dutch mercantile activity along the mid Atlantic coast during the late 16th century and early decades of the 17th century.     

Nuts in the Netherlands: Attalea and other nuts from archaeological contexts,dating from the 16th to 19th century AD

Abstract

This paper describes the use of palm nuts for the manufacture of artefacts in the Netherlands. From the 17th to 19th century buttons were made of nuts of the Brazilian palm tree Attalea cf. funifera. Finds from 17th century shipwrecks suggest that the palm nuts of this species were directly imported from Middle or South America. Coconuts were used for carving, for example for the manufacture of coconut beakers. In the 19th century buttons were also made of 'vegetable ivory' or tagua nut.     

A graph-based analysis for generating geographical context from a historical cadastre in Spain (17th and 18th centuries)

Abstract

The cabreves are notarial documents prepared between the 13th and 19th centuries in the Catalan and Valencian regions of Spain. These historical records were published before the first cadastral maps and contain geographical information that could help spatially reconstruct historical landscapes. However, these documents have not been used to their full potential mainly because of their semi-structured and complex nature. In this article, we propose a new graph-based interactive methodology for partially reconstructing historical landscapes. We have successfully applied this methodology for reconstructing the historical landscape of the Barony of Sella in the 18th century and the methodology has also helped us locate “El Poblet,” a previously unknown archeological site abandoned after the expulsion of the Moriscos in 1609.
