[Cob] natural finishing oil (non toxic!!)

[Ocean Liff-Anderson]

If you want to avoid the toxic solvents and heavy metals in linseed  
oil, the folks at Land Ark (Kiko's neighbors) in Blodgett, Oregon  
have created natural finishing oils, citrus solvent and other natural  
finishes.  http://www.landarknw.com

Here's a page describing the use of their finishing oil on earthen  
floors:  http://www.landarknw.com/Earthen%20Floors.html
