PALJOLLY 120 Pcs Iridescent Glass Petal Mosaic Tiles for Crafts, Stained Glass Supplies, Flower Leaves Mosaic Pieces Kit, Assorted Size and Rainbow Colors

Why I reached for these

I was working on a couple of floral mosaic projects—a glass-on-glass sun catcher and a small decorative plaque—and wanted to speed past the tracing-and-cutting phase that usually comes with shaping leaves and petals. The PALJOLLY petal tiles promised two ready-to-use sizes in iridescent finishes, which sounded ideal for building layered flowers without hauling out my scoring tools for every piece. After a few weeks of use, here’s how they performed.

What’s in the pack

You get 120 glass petals: 60 large (about 1.5 x 0.625 inches / 38 x 15 mm) and 60 small (about 1 x 0.5 inches / 25 x 12 mm), all around 1/8 inch (3 mm) thick. That thickness matches standard stained glass, so they sit nicely alongside sheet-glass offcuts and many commercial mosaic tesserae. The pieces are hand-cut, which is part of the charm and also where some compromises appear.

My set arrived well protected, with only a couple of minor corner nicks. Nothing unusable, but it’s still glass—expect a few imperfect edges and handle it with the same care you’d give any small glass bits.

Build and finish

The finish is an iridescent top layer applied over base colors that span warm (orange, beige), cool (blue, green), and neutrals (black, white, grey). The iridescence on my batch reads more as a pearly, oil-slick sheen than a showy rainbow. Under direct sun or strong directional light, the colors bloom and you get that shimmer you want for floral highlights. Under indoor diffuse light, the effect is subtler—pleasant, but not the dramatic mirror-like flip some product photos suggest.

Edges are slightly uneven from the hand cutting. You’ll see mild asymmetry from petal to petal, and a few pieces have micro-chipping along the edge. For most mosaics, grout will mask this; for glass-on-glass with tight joints or no grout, I hit a handful of edges with a fine diamond hand pad to soften hotspots. It takes seconds and preserves the shape.

Color assortment and consistency

You get a useful spread of base colors, enough to assemble complete blooms (petals plus leaves) without hunting for supplemental glass. I found the distribution perfectly serviceable for mixed bouquets: a good amount of cool greens and blues, a smaller but workable selection of warm tones, and a scattering of neutrals that make nice accents and contrast petals. If you’re aiming for a strictly monochrome or a high-saturation palette (say, all fiery reds), plan to augment with your own glass. The iridescent sheen can reduce perceived saturation in low light; set a few pieces under your project’s intended lighting before finalizing the palette.

Cutting and shaping

At 1/8 inch thick, these pieces cut cleanly with wheeled nippers. You can:

• Split large petals in half to create slender leaves or tapered petals.
• Trim the tip to round it over for a softer, daisy-like look.
• Take a sliver off one side to correct asymmetry if a pair needs to match more closely.

Because the shapes are small, I avoid scoring and running; nippers are faster and put less stress on the piece. Expect a small amount of chipping when taking narrow slivers—again, a quick pass with a diamond pad tidies that up. If you’re working with children, pre-smooth the edges or handle all the trimming yourself.

Working with adhesive and grout

For glass-on-glass, I had the best results with a clear silicone adhesive. It grabs well, doesn’t cloud the iridescence, and cures predictably. Water-based PVA glues (like Weldbond) also work but can leave a faint haze behind transparent colors if applied too thickly. Wipe squeeze-out immediately and clean the glass face with a bit of isopropyl alcohol before it sets.

For opaque substrates—wood, MDF, terracotta—Weldbond or similar PVA is fine. Let adhesives cure fully before grouting.

Joint size dictates grout choice. With close-fitting petals and narrow gaps (1/16 inch or less), unsanded grout avoids scratching and fills cleanly. For wider gaps, fine sanded grout is acceptable, but test on a spare piece first; the iridescent surface handled my charcoal and white grouts without staining. If you’re cautious, a light grout release or painter’s tape over the faces provides insurance and speeds cleanup.

In use: what these do well

• Fast floral builds: The two sizes layer beautifully. A ring of large petals with an offset ring of small petals and a glass cabochon center gives instant depth without much trimming.
• Leaves and vines: The pointy tips read as foliage with a simple orientation swap, so you can extend stems with repeated small pieces.
• Pattern versatility: The shapes also work for feathers, butterfly wings, and teardrop motifs. If you’re doing a hummingbird or butterfly piece, orient the iridescent side to catch light along the wing edges for a subtle glow.

I completed an 8 x 10-inch glass-on-glass floral panel primarily with these tiles plus a few round centers, and still had enough pieces left for a smaller plaque. In terms of coverage, a single pack can comfortably produce multiple small projects or one medium, depending on your spacing and layering.

Where they fall short

• Iridescence intensity varies: The sheen is attractive, but more restrained than some might anticipate. It comes alive in sunlight and raking light, less so under flat indoor lighting.
• Hand-cut variability: Slightly uneven shapes are part of the aesthetic, yet if you need tight symmetry—two mirrored petals for a perfectly balanced flower—you may need to trim or sort more carefully.
• Occasional chips: A small percentage of pieces had minor chipping on an edge or corner. Most of it disappears under grout, but for non-grouted glass-on-glass, you’ll want to be selective or do quick edge touch-ups.
• Not for kiln work: These are mosaic components, not fusible glass. Don’t plan on vitrofusion or kilnforming; the iridescent coating isn’t intended for that environment.

Durability and outdoor use

Once adhered, the glass holds up well. For outdoor mosaics, the limiting factor is your adhesive and substrate rather than the tile itself. Use a weather-appropriate adhesive (exterior-grade silicone or mortar on masonry) and seal grout if the piece will live in freeze-thaw conditions. For stepping stones specifically, the exposed pointed tips can chip under foot traffic; I’d reserve these for vertical or decorative surfaces outdoors rather than walkable ones.

Value and who it suits

Precut shapes are a time saver. Compared to cutting every petal from sheet glass, these let you focus on composition and color decisions. The pack size (60 large, 60 small) is balanced and practical—you aren’t left with a mismatch of sizes at the end of a project, which I appreciate.

These are ideal for:
- Beginners who want an immediate win building floral motifs without learning complex glass cutting.
- Intermediate mosaic artists looking to speed production or add iridescent highlights without committing to full iridized sheets.
- Teachers running workshops where repeatable, safe shapes keep sessions moving.

They’re less ideal for:
- Makers who require exact symmetry and identical edges out of the box.
- Anyone expecting bold, holographic iridescence under all lighting.
- Kiln artists seeking fusible-compatible parts.

Tips for best results

• Pre-sort by tone and sheen. Group warm/cool and more/less iridescent pieces so you can balance a composition quickly.
• Orient for light. Lay tiles on your actual display surface and rotate them; the sheen changes with angle and can turn a flat-looking bloom into a lively one.
• Keep a diamond hand pad nearby. A couple of strokes tame sharp edges and clean up minor chips without changing the piece’s footprint.
• Use clear adhesive for transparent placement. For glass-on-glass, silicone avoids milkiness and keeps the iridescence crisp.
• Pair with round centers. Small glass gems or coin-shaped tesserae make instant, clean flower centers that visually anchor the petals.

Recommendation

I recommend the PALJOLLY petal tiles for mosaic makers who want to build floral and leaf motifs quickly with a tasteful iridescent accent. The convenience of two ready-to-use sizes, workable color assortment, and mosaic-friendly thickness outweigh the minor drawbacks of hand-cut variability and occasional small chips. Just set expectations around the iridescence—it’s elegant rather than flashy—and plan on light edge cleanup for pristine glass-on-glass work. If you need kiln-compatible or perfectly uniform pieces, look elsewhere; for efficient, creative mosaics with a gentle shimmer, these are a smart addition to the studio.
