Knapping Floor Tile

<< < (4/6) > >>

JackCrafty:
On a scale of 0-10 (with 10 being easiest to knap), here is where I place high-grade floor tile compared to other materials:

10  High-grade Heat-treated

9    Glass/Obsidian

8    True Flint and Highest-grade Cherts

7    High-grade Chert and Medium-grade Heat-treated

6    Medium-grade Chert

5    High-grade Porcelain and Ceramic  (includes high-grade floor tile)

4    Low-grade Heat-treated

3    Low-grade Chert

2    High-grade Quartzite and Rhyolite

1    Low-grade Quartzite and Rhyolite

0    Low-grade Ceramics, Natural Cortex


I usually don't recommend anything lower than a 7 for beginners and for those who want to work on advanced flaking techniques.

Note:  This scale has been updated on this thread:   http://www.primitivearcher.com/smf/index.php/topic,52976.0/topicseen.html

Thanks for the input Brian!  What do you think of the knappability scale?

jeffp51:
also thanks.  I can't wait to try it.  I am flying home from Germany tomorrow.

Yes, that is a fair grading system. There is plenty of great materials that far outweigh the floor tiles, but on cheap easy to obtain for most people other than glass....tile is a good practice material, and with your knapping videos that show a step by step....hopefully we will see some success.
