Lanceervensters

Lanceervensters refers to a technique used in glass manufacturing, specifically in the creation of patterned or decorative glass. This method involves the controlled pouring of molten glass onto a textured surface or into a mold with a specific pattern. The term "lanceervensters" (which translates from Dutch as "lance windows" or "spear windows") is often associated with older techniques, particularly those used for stained glass or architectural glass where ornate designs were achieved through such methods.

The process typically involves a ladle or a similar tool to carefully drip or pour molten glass onto a flat surface that has been imprinted with the desired pattern. As the hot glass flows and cools, it takes on the texture and shape of the underlying pattern. This can result in raised or indented designs, or even intricate filigree-like structures depending on the viscosity of the glass and the precision of the pouring. While the term is less common in modern industrial glass production, the underlying principle of pattern transfer from a mold or textured surface to molten glass remains a fundamental aspect of decorative glass creation. Historically, this technique allowed for the relatively rapid production of decorative glass elements that might otherwise have been extremely labor-intensive to create through carving or other methods. The resulting glass often exhibits a unique tactile and visual quality due to the inherent nature of the molten material interacting with the patterned surface.
