Re: [papercreters] Re: Testing R value



Hi Calle,
Yes you are absolutely correct.  The effects of type and amount are what may come out of a good testing program.  I may not be able to test all the parameters of all the different samples, but can do some.  For example, tension tests would be hard for me to accomplish, but compression and shear would be fairly easy.   
Judith has some good data on a burn test but I don't recall the mix.  It would be good to have that as the Portland mix decreased to see where burning becomes a serious safety issue.

Spaceman, does the kind of paper matter? I would think that newsprint is more absorbent, cardboard is less refined, magazines have more additives, and office paper another kind of finish or bleaching process.

So they may react differently. Having pulled sheets of paper for "Handmade Paper" cotton does very different than say fiber from bananas, or tree fibers.

So when the discussion is on being consistent, dosen't that mean paper content also?
Thought we read somewhere that the clay content of the glossy magazines did something to the end product.
