Fiberglass refers to a group of products made from individual glass fibers combined into a variety of forms. Glass fibers can be divided into two major groups according to their geometry: continuous fibers used in yarns and textiles, and the discontinuous (short) fibers used as batts, blankets, or boards for insulation and filtration.

The Glass Bottle Manufacturing Process

Batch Glass Melting Process. In a batch process, all raw materials are added at one time, as opposed to being continually fed into a furnace. The glass is melted in a single vessel or furnace, which is sometimes called a "day tank." Once the glass is melted, a portion of the glass is removed from the melting vessel and is formed into a product.
