FAQs

There is no need to change your clay. You can use the same mix as you were using with natural olivine. If using Green Diamond as a facing sand, you might want to adjust the clays up a little because of the bulk density difference. There is more surface area per pound of Green Diamond

YES. Our studies have shown that the makeup sand, for dry reclaimed Sodium Silicate no-bake, was reduced from 35% with Olivine to 15% with Green Diamond synthetic olivine. Green Diamond sand reclaims faster, easier, and is cleaner than the natural Olivine, and doesn’t break down as easily.

Delivered price of Green Diamond synthetic olivine is very dependent on freight and packaging. Even if the delivered cost is more, you will see savings in reduced makeup sand, lower pouring temperatures, and better finish, which should negate any higher price. Also, since Green Diamond sand is 10-20% lighter in bulk density, there would be

We offer AFS GFN identifiers for each of our foundry products. We prefer that you send us a sand sample to be tested so we can accurately recommend an appropriate size for your facility. In general, our AFS 100 is used by shops that pour only aluminum and have automatic molding machines. AFS 115 is

NO. You can take out 1/4 or 1/3 of your system sand and replace it with pre-mulled Green Diamond, which will accelerate the conversion. Or, you can just stop adding your current system sand source and transition into our synthetic olivine. If you switch from natural Olivine, you will not see any difference in your

No, we only accept spent Green Diamond materials to maintain strict quality control. Participants must sign a recycling agreement and meet handling requirements.

Our Clackamas, OR facility processes spent Green Diamond materials, screening, drying, and refining them for reuse for other products. This program reduces landfill waste and ensures consistent product quality.

Our specialty aggregates are used in industrial flooring, coatings, landscaping, and high-traffic surfaces. They provide superior strength, chemical resistance, and longevity compared to traditional aggregates.

Our granules are designed for durability, UV resistance, and color retention, helping extend the life of roofing materials. They enhance traction, improve weather resistance, and can be used in solar-reflective applications for energy efficiency.

It is widely used for ductile iron, gray iron and non-ferrous metal casting. However, specific applications may require different grain sizes, so it’s best to consult with our team to determine the right fit for your needs.
