Norse Platters from Bornais, by Clara Freer & Ian Dennis, Cardiff University
This paper is based on work by Clara Freer, Ian Dennis, Alan Lane and Niall Sharples on the assemblage from Bornais. Excavated by N. Sharples from 1994 to 2004.
A large settlement located on the machair plain of South Uist in the Outer Hebrides.
Occupation found to spread over five mounds with most mounds contemporary during the Norse period with about 50 – 75 people occupying the site.
It was Occupied from at least 5th century AD through to the 15tb century AD.
Occupation found to spread over five mounds with most mounds contemporary during the Norse period with about 50 – 75 people occupying the site.
Our objectives were:
# Understand the nature of platter production
# Consider manufacturing constraints (including the amount of clay in weight used, the temper, size, styles and different forms found on the Bornais excavations)
# Investigate their use as baking plates, how effective they are and to examine their durability
# Investigate gendered production through an examination of the size of the finger print impressions found on platters from Bornais
# Examine and compare our platters to the ones from Bornais

Jamyia, Ava, Mashay- Solar Energy
- 1. Solar Energy Jamyia, Ava, Mashay
- 2. Company name We put solar cells outside so we can collect the sun energy and turn it into electrical energy.
- 3. Introduce your selves Hi I am Ava and I work to collect solar energy and I have been working here for almost 7 years. I’m Mashay and I help out with the supplies my experience is very high. My name is Jamyia and I help out with the sells.
- 4. Solar energy We put solar cells together to collect the light energy and make electricity.
- 5. Advantages of your source No pollution or waste In sunny countries solar power can be used where there is no way to get electricity Handy for low-power uses.
- 6. Disadvantages of wind It is not a good source because it can kill birds, and can be noisy. Wind is not always predictable
- 7. Disadvantages of nuclear power It is bad because not much waste is produced If it does go wrong, a nuclear accident can be a major disaster
- 8. Disadvantages of biogas We burn the biogas, so it makes greenhouse gases just like fossil fuels do. It’s not good
- 9. Disadvantages of Hydroelectric power The dams are very expensive to build. Finding a suitable site can be difficult. Water quality and quantity downstream can be affected.
- 10. Disadvantages of Geothermal The big problem is that there are not many places where you can build a geothermal power station. Sometimes a geothermal site may "run out of steam", perhaps for decades. Hazardous gases and minerals may come up from underground, and can be difficult to safely dispose of.
- 11. Disadvantages of coal Mining coal can be difficult and dangerous. Burning coal produces more carbon dioxide than burning oil or gas. Coal-fired power stations need huge amounts of fuel, which means train-loads of coal almost constantly.
