We spend a lot of time with glass inside, so it is a real treat to see it in the field - especially on a volcano! We made some borosilicate gas sampling bottles for the USGS Hawaiian Volcano Observatory, and the folks there were kind enough to send these words along with some pictures:

We anticipate many years of happy volcanic gas sampling with them. 
When we have glass needs in the future we will be in touch! aloha, Tamar"

Tamar also clued us in on the orientation of the bottle! Our initial decal was on upside down....
