A virtual mini-museum of the halcyon days of the Canadian pencil industry.
I typically write about graphite or colored pencils on this blog but today I bring you grease pencils. The are sometimes refereed to by different names for example China marking pencil or chinagraph. They refer to the same tool – a soft, greasy wax, commonly wrapped in paper rather than encased in wood. They are commonly used to mark smooth, shiny and non-porous surfaces like China (hence the name "China Marking"), porcelain or glass.
Blaisdell and Dixon appear to have been the two main Canadian manufacturers of grease pencils. I really know very little about the history of Blaisdell in Canada. Blaisdell made wooden graphite pencils in the US but I've never seen any Blaisdell products made in Canada other than grease pencils. If you know more, please let me know.
