Over the years I have amassed a substantial number of casts, mostly of North American Paleoindian points.  The majority were given to me, I bought a few and traded for others.  The main donors were Marie Wormington (Denver Museum of Natural History casts), Geroge Frison and mainly Dennis Stanford (Smithsonian).  I have now made an inventory and find that I have 505 unique (individual) casts and about 40 duplicates.  I have put together an inventory on a spreadsheet with photos.  These casts have been used a lot in teaching, during presentations, as exhibits in a local cultural center, in knapping workshops from South America to China, and as examples I consult during knapping.  Here is an example of a spreadsheet entry:

Reproduction of Stone Artifacts by Casting

I am designing a project to get casting done in South America and have some enthusiastic colleagues who will assist in the process by getting access to items to cast, arranging logistics and possibly funding.  There are several reasons to want to have this done.  Here is a draft outline of the reasoning.  Along with many other motivations, the preservation of selected pieces is critical for the future.  This is not only the case for private collections but the tragic loss of collections in the National Museum of Brazil shows that even where objects are kept in ‘secure’ locations, there is no guarantee of their long-term preservation.




                        Museums and art world





                        Long term     


                        Flexible- Various casting options (eg. Color)


                       Multiple identical duplicates

                       Relatively easy to produce to conventional standards- portable production

                       Reasonable costs (self-sustaining options-commercial)


                       Multiple senses (sight AND touch)          


                       Collections held in institutions and privately


                       Multiple copies/multiple locations







                        Standard methods replication

                        Specialized methods






                        Museum displays/travelling exhibits

                        Public presentations

                        Collector collaborations
