2.4.1. Cross-Section Preparation

Samples for cross-section analysis were embedded in Bio-Plastic liquid polyester casting resin (Ward's Natural Science). Sections were ground to exposure using a Buehler Handimet 2 roll grinder with Carbimet abrasive paper rolls ranging in grit from 240–600. Samples were then polished using a Buehler Metaserv 2000 polisher with 6 μm and 1 μm Buehler MetaDi Monocrystalline Diamond Suspension.
