[Cob] Radiant heat in earthen floors

Tys: A friend of mine did a science fair project where she made up  
test floor panels using water based urethane, oil based urethane and  
boiled linseed oil. She then dropped a ball peen hammer through a  
plastic tube on to the floor samples. The boiled linseed oil out  
performed both urethane panels. We believe this is because the boiled  
linseed oil penetrated deeper into the floor surface. I also tried  
Oil based urethane over boiled linseed oil. The two layers  
delimitated over time.
