Vitreous Enamel: Mycenæan Period Jewelry to First Period Chemistry
Vitreous Enamel: Mycenæan Period Jewelry to First Period Chemistry Date : 17/10/2018 More durable than glass and just as beautiful, vitreous enamel, also known as porcelain enamel, offers a non-porous, glass-like finish created by fusing finely ground colored glass to a substrate through a firing process. Adding to its strength and durability, the substrate used is always a metal, whether precious or non-precious, for its stability and capacity to withstand the firing process. Origins It is unknown who first developed enamelling and when the process was first used, but the most historic enameled artifacts were discovered in Cyprus in the 1950s dating as far back as the 13th Century BC. Scientists have determined the set of six rings and an enameled golden scepter found belonged to the craftspeople of Mycenaean Greece. Enamelling Evolution Metalsmiths first used enamel to take the place of gems in their work, and this was the earliest example of “paste stones,” a common element in both precious and costume jewelry today. In © 2019 PolyVision. is the leading manufacturer of CeramicSteel surfaces for use in whiteboards, chalkboards and an array of architectural applications. Page 1 of 6 this technique, enamel is placed in channels set that have been soldered to the metal. Meaning “divided into cells,” Cloisonné refers to this earliest practiced enameling technique. Champlevé, or raised fields, differs from Cloisonné in the way the space for the enamel is created. Unlike Cloisonné, the Champlevé technique requires carving away the substrate instead of setting forms onto the metal base for the enamel to fill. -
With Carleton Professor Clint Cowan
August 7-17, 2013 (11 days) with Carleton Professor Clint Cowan The "Old Man of Hoy" stands 450 ft. high on the Isle of Hoy, Orkney Islands. Dear Carleton College Alumni and Friends, I invite you to join Carleton College geologist Clint Cowan ’83 on this unique new hiking tour in Scotland’s little-visited Orkney and Shetland Islands! This is the perfect opportunity to explore on foot Scotland’s Northern Isles' amazing wealth of geological and archaeological sites. Their rocks tell the whole story, spanning almost three billion years. On Shet- land you will walk on an ancient ocean floor, explore an extinct volcano, and stroll across shifting sands. In contrast, Orkney is made up largely of sedimentary rocks, one of the best collections of these sediments to be seen anywhere in the world. Both archipelagoes also have an amazing wealth of archaeological sites dating back 5,000 years. This geological and archaeological saga is worth the telling, and nowhere else can the evidence be seen in more glorious a setting. Above & Bottom: The archaeological site of Jarlshof, dat- ing back to 2500 B.C. Below: A view of the Atlantic from This active land tour features daily hikes that are easy to moderate the northern Shetland island of Unst. in difficulty, so to fully enjoy and visit all the sites on this itinerary one should be in good walking condition (and, obviously, enjoy hiking!). Highlights include: • The “Heart of Neolithic Orkney,” inscribed as a UNESCO World Heritage site in 1999, including the chambered tomb of Maeshowe, estimated to have been constructed around 2700 B.C.; the 4,000 year old Ring of Brodgar, one of Europe’s finest Neolithic monu- ments; Skara Brae settlement; and associated monuments and stone settings. -
Glass and Glass-Ceramics
Chapter 3 Sintering and Microstructure of Ceramics 3.1. Sintering and microstructure of ceramics We saw in Chapter 1 that sintering is at the heart of ceramic processes. However, as sintering takes place only in the last of the three main stages of the process (powders o forming o heat treatments), one might be surprised to see that the place devoted to it in written works is much greater than that devoted to powder preparation and forming stages. This is perhaps because sintering involves scientific considerations more directly, whereas the other two stages often stress more technical observations M in the best possible meaning of the term, but with manufacturing secrets and industrial property aspects that are not compatible with the dissemination of knowledge. However, there is more: being the last of the three stages M even though it may be followed by various finishing treatments (rectification, decoration, deposit of surfacing coatings, etc.) M sintering often reveals defects caused during the preceding stages, which are generally optimized with respect to sintering, which perfects them M for example, the granularity of the powders directly impacts on the densification and grain growth, so therefore the success of the powder treatment is validated by the performances of the sintered part. Sintering allows the consolidation M the non-cohesive granular medium becomes a cohesive material M whilst organizing the microstructure (size and shape of the grains, rate and nature of the porosity, etc.). However, the microstructure determines to a large extent the performances of the material: all the more reason why sintering Chapter written by Philippe BOCH and Anne LERICHE. -

Ed met the group for dinner in the evening, while the plan for the following days was laid out. Weather: dry and bright weather, but soon cloud and drizzle spread from the west. Day 2: Stenness Standing Stones, Ring of Brodgar, Yesnaby & Marwick Head Friday 4 May 2018 After breakfast we drove a short distance to our first destination – the Standing Stones of Stenness. A Neolithic monument, the stones may be the oldest henge site in the British Isles. Various traditions associated with the stones survived into the modern era and they form part of the Heart of Neolithic Orkney World Heritage Site. Handsome hooded crows called from the surrounding rabbit-filled fields. We wandered over to the nearby Barnhouse Settlement before reaching the hide overlooking Loch of Harray – the largest on Mainland Orkney. Whilst a wide variety of wildfowl winter on the loch, it was remarkably quiet during our visit, save for around 50 mute swans. A few tufted ducks, red-breasted mergansers and coots were also seen nearby. We returned to our minibus via the Stones and paused for a while to view the large, brackish Loch of Stenness. Several common seals were resting in the shallows in their classic ‘banana’ pose, much to the amusement of the group. -
Mid Howe Chambered Cairn

While every effort is made to keep them up to date, they should not be considered a definitive or final assessment of our properties. Historic Environment Scotland – Scottish Charity No. SC045925 Principal Office: Longmore House, Salisbury Place, Edinburgh EH9 1SH Historic Environment Scotland – Scottish Charity No. SC045925 Principal Office: Longmore House, Salisbury Place, Edinburgh EH9 1SH MID HOWE CHAMBERED CAIRN BRIEF DESCRIPTION Alternative Spelling: Midhowe. The monument comprises a neolithic chambered cairn used for communal burial. It falls into a broad tradition of stone-built chambered cairns which started in Scotland in the 4th millennium BC. A short passage leads to a long interior divided by pairs of upright stone slabs into 12 compartments, some with low stone benches. The remains of at least 25 human skeletons were found, mostly lying on these benches, as well as some pottery, worked flint and animal bones. Walls, perhaps forming an enclosure, spring from the NE and SE corners of the cairn. The original roof does not survive since it had collapsed in situ. Secondary use of the site has been recognised but little understood. The tomb was excavated in the early 1930s and enclosed shortly afterwards within a stone-built ‘hangar’ within which visitors can walk around and over the tomb. Situated on the south coast of the island of Rousay, this large cairn is accessed across steep fields from the road on the hillside above, or from the Westness Heritage Walk, which runs along the coast.
