3 CONCLUSIONS

THE WORK presented here has identified the nature of the pigments on samples of Canosa ware in the collection of the J. Paul Getty Museum. Some of the pigments from these vases are very fragile and may require surface consolidation to ensure their stability. The range of pigments used is quite typical for the period of manufacture in the early centuries B.C., although it is unusual to see rose madder used as ceramic colorant; this material would burn out in firing and so be lost in a fired ceramic surface.
