You might consider >a chemical supply house. Check your yellow pages. Be very careful! Glacial acetic acid is 100% and must be diluted with four parts of water to make a 20% solution. Mary needs to make up 1.2gal of acetic acid to 6gal to obtain a 20% solution. If you must, do it outdoors, upwind of the acetic acid pouring and mixing. Wear the appropriate protective clothing. It is nasty stuff. Megan wrote: >I would recommend price costco/ sam's club/ b.j's or whatever other >wholesale place you can find, and then doing a silution to get the 20% >concentrate. Cookbook chemistry and all! No. You won't find glacial acetic acid for sale in those places. I would recommend buying the stuff already diluted to 20%. Call any local restaurant supply house (try Food Products-Whsle in the yellow pages) and they will tell you the nearest place to get it. Regards, Cameron.
