Yes. Glass has been around for about 9000 years and glass bottles were produced 3500 years ago. The Jamestown settlers made glass bottles and jars in the early 1600s. Glass jars for preserving food were sealed with a flat tin lid and wax until 1858 when John Mason invented the Mason Jar with a screw-on lid. By 1864 a glass jar would look very similar to a modern peanut butter jar.

What are five types of glass?
There are a lot, but here are some: 1. Fiberglass-fine, solid rods of glass, each of which may be less than one-twentieth the width of a human hair-often used for protective clothing, insulation, etc. It is fire-proof 2. Flat glass-used for mirrors, windows, room dividers and some furniture. 3. optical glass-the glass that makes up your glasses and used for other optical equipment 4 Opal glass has small particles that disperse the light passing through it, making the glass appear milky. This glass is widely used in lighting fixtures and for tableware. 5. Foam glass, when it is cut, looks like a black honeycomb. It is filled with many tiny cells of gas. Each cell is surrounded and sealed off from the others by thin walls of glass. Foam glass is so light that it floats on water. It is widely used as a heat insulator in buildings, on steam pipes, and on chemical equipment. Foam glass can be cut into various shapes with a saw. Hope this helps!

Was stained glass used in the Gothic time period?
Stain glass was made pretty much how it is made today. A pattern is made, the glass is cut on the pattern and then it is put together with lead. Of course the glass its self is made differently and the patterns used were all religious. A "glazier" made the glass and a "glass painter" drew the details and finished the window. Many times they were the same people. Glaziers worked closely with masons, carpenters, and smiths on various buildings and they were also used to maintain and repair windows. One of the first structures to be redesigned in the Gothic style was Sanit-Denis, north of Paris and the windows were added at this time as an important part of the life and faith of the community. Stain glass embodied the way people viewed their relationship to God. The theme of light appears over and over in the Bible, so light was connected to God and the light passing through the windows was a visible reminder of the divine.
