Tim Rast, a Canadian archaeologist and flintknapper, uses his blog, “Elfshot: Sticks and Stones” to communicate his discoveries in the field of experimental archaeology.  He is a highly qualified authority within this field.  His commentary offers a complete approach; from research, to construction, to reflection – he offers insight on every factor of the object.  Also, as he creates replicas for museum and academic applications, there is a bit of interesting stuff about how to replicate patinas, and his approaches towards materials and pigments are especially interesting when one thinks about how these activities can be reflected within the archaeological record.  Great Stuff!                                http://elfshotgallery.blogspot.com/
