List,

Not long ago there was a thread on lacquer. There was some discussion 
about water white nitrocellulose but there was no mention on where to 
obtain it. I looked around the area and no stores handle water white 
nitrocellulose. This lead me to the web. Here is a link with a basic 
description if you are interested:

I'm not an expert on web searches so it was impossible for me to find 
any distributors of this product in the east. I did find the product 
and a distributor in CA. The product is from US Cellulose and the 
distributor is Liberon Supply. Here is a page from their site:

Unfortunately one cannot buy anything smaller than a gallon. The price 
is reasonable for the gallon but with the shipping and HASMAT fee it 
costs $47.63. Well what the heck, I bought one!

The gallon arrived yesterday so I have not had a chance to try some 
hammer hardening with it. The solids are 24% by weight and it is fairly 
clear. Mixed with thinner it looks very clear. Eric Schandall was here 
for a visit last week (another story) and he gave me a bit of the 
Steinway mix that is unavailable to us. Attached is a pic of four 
bottles with different hardeners. From the left, the first is standard 
nitrocellulose lacquer from most hardware stores, next is the Steinway 
mix(3:1), US Cellulose mix (5:1) and finally the acetone mix from the 
Pianotek pellets. If the reproduction on your screen is accurate, the 
US Cellulose is the most clear of the four.

The information from the woodweb site says that water white will yellow 
with time. Of course that is on wood applications. It will be 
interesting to see how the hammers will look in time. How much time is 
anyone's guess.
