Fused glass powder for fine-filler blend design
A fine fused-glass filler for resin-bound engineered-stone makers shaping a dense mineral blend, smooth surface and repeatable mixing route. Select a particle cut that fits your slab design, then compare the material with your plant’s resin system and intended surface finish.
Designed for controlled powder blending
Use this powder when the formulation calls for a fine glass-derived fraction alongside coarser aggregates. The fine cut can be assessed for blend packing, dispersion and the way exposed particles read after curing and polishing. It is suited to development work where the buyer wants to tune powder-to-grit balance, surface appearance and process handling before selecting an incoming-material control plan.
| Property | Recorded sample result | How buyers use it |
|---|---|---|
| Color, L*a*b* | L* 98.83 · a* 3.36 · b* −0.27 | Compare shade under the same sample preparation and instrument conditions. |
| Moisture | 0.18% reported | Review storage and dosing needs for the selected resin process. |
| Material above 45 μm | 14.50% by mass in the recorded sample | Specify the retained fraction and acceptance range to suit your resin blend and processing requirements. |
Where the powder fits
In a slab line, the powder is selected as part of a combined aggregate system rather than on its own. Compare it with the planned grit fractions, resin viscosity and mixing sequence. During a lab or pilot run, record dispersion, dry spots, settling, press response and the polished surface. The useful specification is the one that connects the received powder to the buyer’s blend and finished slab requirements.
| Application | Selection focus | Trial check |
|---|---|---|
| Resin-bound engineered stone | Fine fraction within a multi-size mineral blend | Powder distribution, mixing and cured-surface uniformity. |
| Decorative slab development | Color contribution and visible particle texture | Side-by-side sample panels under agreed lighting. |
| Incoming material qualification | Sieve cut, moisture and lot variation | Current COA and a repeatable sampling method. |
Choose the grade around your blend
Share your target size curve, the apertures used on your line and whether the powder is a background filler or a visible feature. If the blend already contains a fine silica or glass grade, compare flow, resin demand and finish before substituting. A trial should hold the binder, pigment, pressing and cure conditions steady so that the powder change can be assessed clearly.

Frequently asked questions
Can the 45 μm sieve residue be specified for different customers?
Yes. The required sieve residue depends on the slab formulation and processing route. Provide your target retained fraction, sieve method and acceptance range so the grade can be agreed for your application.
What should I specify in an RFQ?
Give the sieve apertures and acceptance limits, target color, moisture method, sample amount and the resin-bound application so the supplier can confirm a suitable grade.
