4. Low moisture content: <1.0%
5. Available in 250g, 500g and 1.5kg packaging options

Uses:

1. Ceramics and pottery glaze formulations
2. Glass and frit production
3. Paints, coatings and resin filler applications
4. Laboratory and research use
5. Industrial polishing, casting and refractory mixes

How to Use – Popular Applications:

1. Ceramic Glaze Additive
   Weigh the required amount, typically 10g–100g depending on batch size. Mix thoroughly with glaze ingredients and water. Wear a dust mask and gloves. Avoid inhaling fine powder.
2. Resin or Epoxy Filler
   Add gradually at 5–30g per 100ml of resin, depending on desired thickness. Stir slowly to reduce airborne dust. Use in a ventilated area.
3. Paint and Coating Filler
   Add 20g–200g per litre of coating mixture. Disperse evenly using mechanical mixing. Test a small batch first for finish and viscosity.
4. Refractory or Casting Mixes
   Combine with other dry minerals before adding liquid binder. Typical use may range from 50g to 500g per kilogram of dry mix. Wear eye protection and respiratory protection.
5. Laboratory or Research Samples
   Measure using calibrated scales. Keep container sealed after use to prevent moisture absorption. Follow your laboratory safety procedures and SDS guidance.
