[CAUT] Hot Hide glue woes (??)

[Fred Sturm]

Hi Michelle,
     Pianotek's hide glue was beautifully clear and yellow about ten  
years ago. More recently it has been a bit more on the brown side.  
Not as murky as what I used to get from APSCO, but in that direction.  
I don't think it is a real problem in terms of function - maybe a wee  
bit weaker, but not significantly. The clear yellow was  
extraordinarily pure. I showed some to a violin maker I know, and he  
was amazed and had to get some right away (I referred him to  
Pianotek). More recently he has been complaining that it isn't as  
good now.
     Of course, if you have high humidity, you can get various  
microorganisms infecting it, even during storage when dry. That can  
cause cloudiness and stink (and how!) if it gets acute. If you don't  
have bad smell, it's more likely impurities in the glue.
