Fusing Straight Lines

This is part two of a multi-part tip on fusing to achieve sharp, crisp lines.  Click here to go to part one, which also includes an example photograph.

In addition to the "flip and fire" approach (discussed in part one of this tip), there are a number of other factors that contribute to sharp, crisp lines in a piece made with strips of glass laid on edge and fused.

Here are some of the most important:

1.  The flatness of the glass

Strips of machine rolled glass will fuse straighter than strips of hand rolled or textured glass.  This is because the individual strips fit closer together, leaving less room for lines to wander and create a wavy appearance.

2.  The quality of the cut of the strip

Strips that are cut with clean edges that form a ninety degree edge fuse crisper than strips with edges that are uneven or angled crooked. 

3.  The thickness of the piece

Wider strips will generally allow for more movement, leading to more waviness than narrow strips.  To the extent that a piece is greater than two standard layers in thickness (1/4"/6mm), the glass on the top is less likely to have straight lines.
