jmw,
Don't fret, no offense taken. Chances are these are old carboys that we're probably sitting around in someones basement for a long time. I didn't quite get the joke anyway. I was assuming that it had something to do with the gas leak from the US company over there that took out a lot...
Thanks all for the information. The acid baths basically had me scared off anyway. All I know about the carboys is that my father had acquired them to make berry wine in. I don't believe he used them and he's since passed away so no history is available.
I'll use my best judgement on how...
The galvanized SIP (stay in place) forms that you see under bridge decks are only forms. Once the concrete is cured their job is done. Usually, the bottom or the corregations are filled with strips of styrofoam to reduce deadload so they're not composite. This also gives a uniform slab depth...
I have aquired two glass carboys that I wish to use for brewing beer and making wine.
I don't know their source or what has been stored in them in the past. There doesn't appear to be any residual liquid remaining in them. One has a styrofoam insulating cup that comes about a 1/3 of the way...
