It was a molten string of glass was wrapped around a clay body which assembled the shape of a vessel. Once the entire object was coated with glass it was cooled, it took more than 12 hours. The clay was chipped out then a glass bottle was made.The blow pipe was invented around first century B.C. It was a long hollow metal rod the tip of it was put into molten glass. The glass tip was blowed into the rod then the mold was turned into several forms.

The recipe of sand wool and ash would result in a greenish colored glass. They then tried different substances to get more array of colors. ( mostly metallic oxides).

It is just something to note that the main purpose of the glass house was not to supply the early americans with bottles, window glass or drinking vessells , it was intended to be shipped back to England, where there were know forest left to fuel the glass house furnaces and to supply the glass for the mixture. They do not believe that any glass was made in Jamestown.

In 1739 the first sucessful American glasshouse was started in New Jershey by Caspar Wistar who had came from Germany.
