1. Start with your project requirements

Before you compare any flat glass beads in bulk, write down these points:

• Use context: epoxy or other decorative flooring, building facades and decoration, lighting fixtures, or handicrafts.
• Size window: the bead size your design, layer thickness or fixture allows.
• Shape: flattened oval, round, or a true flat-back or flat-bottom profile.
• Color and finish: transparent, solid colors, or special effects.
• Wear exposure: foot traffic, abrasion and light exposure.
• Commercial terms: quantity, packaging, delivery schedule, budget and any certification your market needs.

The product information covers the first five points in part. It does not cover the commercial terms.

2. Published specifications

The Glass Cashew Nut Stones and Flat Beads product page lists these parameters:

These are supplier-published values. Before you approve a bulk order, check them against samples and the documents attached to the order.

3. Selection criteria explained

Dimensions

The listed size range is 12–17 mm. If your project needs beads outside this range, the standard specification does not fit. The supplier says it accepts custom size requests, but you need to confirm feasibility and tolerances case by case. Because the range spans 5 mm, ask which size or sub-range will ship. Don't assume one uniform size across the whole range.

Shape profile

The beads are described as having a flattened oval geometry, with flat oval consistency above 98%. If you are searching for flat round glass beads, or for glass beads with a flat back or flat bottom for gluing or embedding, note that the material does not describe a flat-back or flat-bottom profile. Confirm the cross-section with samples before you commit.

Material properties and wear

The listed Mohs hardness is 5–6 and density is 2.4–2.6 g/cm³. The supplier says this hardness helps the beads resist scratches and wear in high-traffic flooring. How the beads perform in your floor also depends on the binder, the topcoat and how it is installed, and the published material does not address those. Ask your flooring system supplier whether the beads suit the system.

Optical effect, color and finish

The listed refractive index is 1.50–1.90 and depends on composition. A higher value means more light refraction, so if light play is important for lighting fixtures or decorative surfaces, ask which composition and refractive index applies to the color you order. Six standard colors are listed, plus pearly, fluorescent and iridescent finishes. Custom colors can be requested. The supplier describes the colors as fade-resistant, but the material includes no test method or duration. Request supporting data if your project faces long light exposure.

Use context

The listed applications are building, flooring and crafts. The product descriptions also mention lighting fixtures and building decoration or facades. If your use falls outside these categories, there is no published guidance for it, and you should treat the recommendation as not applying until the supplier confirms otherwise.

4. What to confirm before placing a bulk order

The published product material does not state these points. Get them in writing:

• Price, minimum order quantity and price breaks for bulk quantities
• Lead time and current stock for your chosen colors and finishes
• Packaging format and unit weight
• Any certifications, test reports or compliance documents your market requires. The supplier mentions internal testing for hardness and color consistency but cites no certificate.
• Size tolerance and batch-to-batch color consistency for repeat orders
• Shipping terms to your destination

5. When this product is a good fit, and when it isn't

Likely a fit: decorative flooring, building decoration, lighting and craft projects that need flattened oval glass beads in the 12–17 mm range, in transparent, standard colors or special finishes.

Not covered: beads smaller than 12 mm or larger than 17 mm, true flat-back or flat-bottom profiles, and structural or load-bearing uses.
