PHOTOMICROGRAPH

Due to variations in printing, do not employ photomicrographs to match colors. Substrate, if present, and earliest layers are located at top of photomicrograph.

STRATIGRAPHY

Cast iron substrate is not present in photomicrograph. The following stratigraphy is derived from both embedded and loose sample fragments.

LAYER	COLOR	MUNSELL	COMMERCIAL	COMMENTS	REACTION
1	red/orange	1.25YR 5/12	MS 129-3	red lead primer	Na2S +
2	bright yellow	1.25Y 7/12	P&L 1764	chrome yellow?	Na2S +
