1 6. 6. - - Fuel to the flame Fuel to the flame z Sources of fuel and its use z Heating: z Little ice age (13 th century; lasted ~200 yrs) triggered changes in living patterns of European community. Could have been caused by sun spots. Simple Chimney -> underfloor heating out through an outside chimney -> strengthen chimney supporting more than one room. z Architectural changes: fireplace’s hood prevented sparks from reaching the ceiling -> lower ceilings. z Social changes: heated rooms introduced the concept of privacy -> romance. Refined life styles. Scientists do not quite agree on the initial date and therefore on the duration of the Little Ice Age. Some scientists claim there were at least three additional minima in temperatures in Northern Europe between the 15th and the mid 19th century. For the purposes of this class, we will said that it lasted for the first 200 years starting in the 13th century, when its effect was most prominent on Europeans. The cause of the Little Ice Age is also matter of debate but a leading theory attributes it to the unusually low sun spot activity during that time.

2 Glass Production Glass Production z What is glass? z Not a crystalline solid, not a liquid. It is a “frozen” liquid. z Glass industry before the 16 th century. By 1580 glass production increased. Efficient furnaces and lots of wood. z Two main types of glass: broad glass (for larger frames, poured in cylinder and rolled open); crown glass (smaller pieces, used blowpipe) z Consequence: wood depletion in England during 16 th century. z Response: Coal furnaces. 1611 Edward Zouch. The states of matter are: Solid, Liquid and Gas. The different among these states is the amount of kinetic energy contained in each state. Gas state is the one with the highest total kinetic energy whereas solid is the lowest -particles loose all translational motion. A solid structure corresponds to a very organized arrangement of particles where particles are periodically separated from each
