How to Store Leftover Stained Glass Sheets and Scraps

Once you''ve bought glass for a project, you''ll almost always end up with leftover sheets or scraps. Storing them properly protects both the glass and you.

Storing Full and Partial Sheets

Store sheets vertically rather than flat whenever possible, standing glass upright in a slotted rack or against a wall on padded supports distributes weight more evenly and reduces the risk of a heavy stack cracking a sheet at the bottom. If vertical storage isn''t available, flat storage works, but avoid stacking too many sheets directly on top of each other without a soft layer, like cardboard or foam, between them to prevent scratching.

Storing Scraps and Cut Remnants

Small scraps are worth keeping, they''re ideal for practice cuts and small pattern pieces on future projects. Sort them loosely by color into labeled bins or boxes, so you can find a matching piece quickly rather than digging through a mixed pile when you need one specific color for a small future piece.

Safety While Storing

Even smooth-edged glass can have sharp corners from cutting. Store scraps in a container with rigid sides rather than a soft bag, and consider wrapping sharp-edged remnants in a layer of paper or cloth before boxing them, both to protect the glass and to protect your hands the next time you reach in.

Keep It Away From Temperature Extremes and Moisture

Glass itself is fairly stable, but a damp storage area can affect any protective coatings on colored or dichroic glass over time, and repeated temperature swings, like an uninsulated garage in a cold climate, add unnecessary stress to sheets, particularly larger or thinner ones. A dry interior space, even a closet shelf, is a better long-term home than an exposed outdoor structure.
