River Garnet Source
Alluvial river garnet is selected for stable mineral quality, cleaner material and reliable abrasive performance.
SEPPE controls the conductivity of 20/40 and 30/60 blasting garnet at no more than 100 μS/cm. This article records the ASTM D4940-based test procedure and a 20/40 garnet result of 58 μS/cm after deducting the test-water reading.
Conductivity testing estimates water-soluble ionic contamination in a blasting-abrasive extract. It does not identify individual ions or assess waterjet feed stabili
This guide explains how to select SEPPE garnet grades, request samples and technical documents, arrange application testing, and use the results to prepare a manageable first bulk order.
