TEOMCROTE = TEOTWAWKI on steroids! The End Of Mankind's Current Reign Over The Earth takes into account that our ancestors were neither suicidal, stupid, nor our genetic inferiors but still wound up getting wiped off the Earth. Whereas CSER [cser.org: Centre for Study of Existential Risk] tries to PREVENT this dispensation from coming to an end, TEOMCROTE works from the eventuality/possibility/probability that the end our age takes place and what to do then

Re: glass


As glass is cooled, it becomes easier to shape into forms, but it must continually be reheated during the glass manufacturing process to add strength to it to avoid shattering. This procedure is known as annealing. An additional tempering process to strengthen the glass is also employed by reheating it and then cooling it suddenly with blasts of cold air.

The most common shaping method in the glass manufacturing process in ancient times involved blowing air into a ball of molten glass at the end of a long, hollow pipe, which the Romans perfected for making beautiful vases and bowls. Float glass manufacture, invented in 1959 by a British company, is the largest current production method done by pouring molten glass into a tank with melted tin on the surface. The glass floats on top of the tin and forms into extremely smooth sheets which can then be cut into window shapes. Dolomite is often included in sheet glass manufacture at levels below 0.1% to maintain the colorless quality of the glass. Drawing a stream of molten glass around the inside of a metal cylinder as it rotates and air is pumped in, is another frequent glass manufacturing process used to make a wide array of glass pipe for light bulbs, vacuum tubes, and glassware used in laboratories.

Other types of specialized glass include lead glass, which contains at least 20% lead oxide and is brilliant when cut and faceted. Heat-resistant glass products used in cooking bowls and labware are made by adding 5% boric oxide or aluminosilicate compounds. Colored glass products are made by adding iron sulphides for brown and amber colors, iron chromate for green shades, and white cobalt for shades of blue. Natural blown glass has a red to orange color without requiring any chemical additives.

basic ingredients


After some research, it appears that glass basically is about

- 70-74% sand
- sodium carbonate
- lime

SAND: as far as i get it, non-tropical beaches offer acceptable sand; it should be sand-colored [certainly not black sands on the island of La Gomera], and of uniform-sized grains.

SODIUM CARBONATE; [not to be confused with sodium bicarbonate, which also has many uses]. Assuming beach sand is good enough and one doesn't have to go to the Sahara for good sand, sodium carbonate can also be acquired at the beach [as can lime]: burning seaweed offers unpure but acceptable sodium carbonate; one burns them down to their white ash state; the white ash is largely made up of sodium carbonate.

LIME; lime can be made by burning seashells.


Magnesium oxide and aluminum oxide are ingredients that are also mentioned in relation to making glass. Of course there are many kinds of glass with many different qualities, so the ingredients that might be added are virtually unlimited, as are the ratios.

In the glass industry also, potash feldspar is used in varying proportions. It may contain 10 to 15% of the batch. Feldspar, in this industry, is valued for two purposes, firstly, it acts as a flux and secondly, for alumina content. Alumina provides the resistance in glass to impact, bendings, and thermal shock.
