When and Where was lead crystal first produced?
Probably by Ravenscraft in England during the 17th century. When lead oxide was added to the "frit", there were often impurities in it and, at first, there wasn't any knowledge of how much should be added. Accordingly, glass from that period often suffers from what is known as "crizzling". This is a gradual disintegration of the glass, typically through the loss of its transparency via a sort of white clouding of the metal.

How could you use thermal expansion to help get a tight lid off a jam jar?
Heat the metal lid (but try not to heat the glass jar as much) and the thermal expansion will make the lit easier to screw off (I do this often by running the lid under hot tap water).

A lot depends on the TYPE of metal shavings you have in the pan. Larger "pieces" of shiny metal can often be broken rings and will be accommodated by oil burning, rough running, etc. Much smaller fragments can be rod bearings. Much depends on how the engine is running. More info on that would be helpful

A patio set is best determined on what the consumer is looking for. If your family often spends time outside on your patio you may want to invest in a patio set. If it rains often you may not want glass with metal, because it may rust. Ultimately this decision is up to the consumer.

Plastic or glass allow the microwaves to penetrate the food and heat it. Metal reflects the microwaves and can damage the microwave oven. Some plastics can melt from heat transfer so glass is best.

What is the tang of a knife?
That tang is the part of the knife that goes into the handle. Full tang means that the metal goes the full length of the handle which helps both the strength and the balance. There is no screw or rivet attachment of the blade to the handle because the blade metal runs straight through to the end of the handle. This makes the survival knife much stronger. In fact, some survival knife models have the metal extend beyond the end of the handle so that the end of the handle can be used as a hammer. This hammer, often referred to as a pommel, can be used to pound tent stakes into the ground, to hammer loosened nails, for breaking glass to exit from a motor vehicle crash, or for good old fashioned self defense.
