Karl Lee pressure flaking glass

This is a link to a short video of Karl Lee pressure flaking glass . It is of interest to me because it illustrates how he uses his knee “like a vice” to remove the flake. The large piece of glass was modern, and probably a table top. This is the end result.

Glass Kimberley Point by Karl Lee

Today we had Karl Lee for the day, demonstrating and producing various pieces for three different research projects including my own. I tasked him with producing a Kimberley Point from the second piece of modern 6mm plate glass found at Chorlton Water Park. He did a pretty good job as can be seen above. Because the glass had a hole and a bevel Karl thought it was toughened table glass which would explain why it was difficult to get the removals to travel. He did however do a better job than me, and I think shape wise his is more characteristic of what would be described as a Kimberley Point. The day was pretty successful, however for me disappointing. For various reasons I wasn’t able to capture the video footage I wanted, and I had to miss the end of Karl finishing my point and so didn’t see first hand how he serrated the edges (although I did leave the camera running and so have got it). We didn’t go through the platform preparation either and so I think a trip to see Karl is in order. We can spend a bit of time playing with stuff, rather than cramming it all into one long day.

A glass point made by Karl Lee


This is one of two glass points made by Karl Lee. The glass itself is quite old, and removed from a metal grid that overlay a cellar. I think these blocks are called cellar lights. Each glass block was in differential condition, and they all proved really difficult to extract (thanks to Joe Curley). However, once out they were workable. Metin Eren used one of the blocks to make a point and described the material as good to work with. Karl had two blocks and produced two nice points, one of which went to Joe Curley. Although I never got to see the finished Metin Eren point, I did observe him producing the early stages. His style is interesting and seems different to Karl’s. With his knapping hand Metin rested his elbow on his knee, thus reducing variability from the shoulder. The only moving joints were his elbow and wrist and it allowed him to concentrate on where he needed to hit. This seemed to make sense and I have adopted the same approach.

Karl Lee making a handaxe

This is an edited video of Karl Lee making a handaxe. The handaxe making took around 20 minutes and it has been edited down to two minutes. The editing process was really interesting as it involved lots of watching and re-watching in order to discern exactly what was going on. My own knapping ability seemed to improve automatically after producing the video. I am definitely a visual learner but really surprised myself. The soil pipe handaxes were an unintended result of this process.

This is an edited video (two minutes only).
