Bronze Wear Primer Paint and Paper Fiber

Bronze Wear, Primer Paint, and Paper Fiber

These particles are from a transformer oil sample. The red particle is a fragment of red primer paint. The two "gold" colored particles are bronze (CuZnPb). There is a small copper particle to their right. The paper fiber is significantly degraded as indicated by its low birefringence and its terminations.
