Subject: RE: data

Sorry- we have a few issues with releasing the data that I am trying to work through. Hoping to have 

them fixed later today, but not looking good.

Please note the following:

- Because of monetary concerns and potential for proprietary formulas (yes- the mix of clay and 

shale in a product can be confidential), we asked facilities to submit green brick for our testing. While we 

occasionally received a single raw material, I believe, the vast majority were already mixed samples for 

one of the brick bodies at the facility. Identifying the clay formation may be difficult. 

- We did not gather any information on the clay formation. We can attempt to gather this 

information quickly (within the constraints listed above concerning mixing). Are there any other factors 

you would like us to collect at the same time. We are hoping to get information on whether the sample 

was clay, shale or a mix.... but again, that is one of the few areas where confidentiality between sources 

may come up.

We will be sending the info to you in its raw form. We are concurrently working on our thoughts about 

where the data may lead. We look forward to talking with you as soon as you have been able to review it, 

as well.

I will send the information as soon as I am cleared to do so.

Sharon- sorry this is taking longer than I hoped. We are closing in on approval from everyone- but I have 

been waylaid... First by the birth or my grandson at the end of last week (!).... And now by our annual 

meeting. I will be trying to pull all approvals together between meetings today and will try to get you the 

raw data tonight... If not tonight, it will likely be Friday. I apologize for this in advance. We are trying to get 

you everything we have since we continue to believe that the floor should be based in more than 3 kilns, 

plus we want to show you overall variability... We will send you our thoughts on the data later- I do not 

want to hold up the submittal by my need for approval of our thoughts.
