4. Cutting drapery glass

This type is different and unique, unlike other glasses in the previous section. Whenever you come across a cloth-like, well-folded, and wavy glass usually associated with uneven thickness, then it’s a Drapery glass. Drapery glass has its front and rear side not equally thick, meaning it’s not flat. It could significantly affect the cutting and overall ease of handling this glass.

A glass ring saw befits this purpose due to its ability to cut in any direction in a bid to cut properly. Often, this glass is fused and stained in nature; i.e., it is a product of different melted glasses with different colors, which makes it stained. For this reason, before advancing to cut this glass, you must score the pattern with the saw. Scoring involves making an initial outline of the pattern you want to cut. Scoring the glass helps avoid any possible breakage or chip falling off the edges.

As you set out to cut, you need to observe the following features of the drapery glass. Firstly, on the front of some drapery glass, the folds appear to be reversed while the rear is hollow. In other cases, the rear side is flat, and the folds are on the front with visible thickness in places.

Secondly, after carefully classifying the nature of the drapery glass, you must cut from the surface with the least irregularity. Watch for the drapery glass’s reverse side to mark your pattern over the drape’s front side. More irregularities imply thicker glass, which makes it more challenging to cut than a flat side or lesser irregularities.

Thirdly, position your glass so you can easily cut the proposed pattern. Lastly, ensure you score the outlined pattern before fully cutting with the glass ring saws.

Note that you need not polish your workpiece with the glass cutting ring saws as the cut is always perfectly executed.
