SC - RE Isinglass

[Trierarch at aol.com]

Hi,
The substance called isinglass is a substance used like a gelatin.  Gelatin 
like we know today comes  primarily from  bones.  The first recorded 
documentation regarding "gelatin" was about 1682.  Isinglass however has a 
longer history, it is a type of gelatin extracted from the air bladders of 
certain fish, particularly sturgeon.  It can be purchases today in dry or 
liquid forms (with or near things like Irishmoss) and is used primarily for 
clearing yeast and other suspended particulates from beer.   Hope this helps.

    Just something to think about... It's my understanding that the
    substance called isinglass, used to preserve eggs, is in fact sodium
    silicate solution, a thick, glycerine-like syrupy stuff not actually
    related to the fishy product, more closely related in fact, I
 suspect,
    to glass, hence the chemical name.
    Have you run across any information on this question in your
 research?
 
 Hmm, no. Thanks, I'll pull that part of the commentary until I can check it
 out. 
 The article just called it isinglass. Another multi-purpose term. Arrgh. >>
