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. >>
