Typical LR Corinthian “red brick“ fabric, firing, and surface. Very thick webbing and thin, sharp joining ridge at seam; good alignment.
Preservation comment
One large sherd preserves ca. 50% of back to middle top of lamp, including most of discus and shoulder and entire handle. Slight to moderate, sparse abrasion and pitting; mostly clean breaks; large, thin, irregular patches of encrustation.
