Tutorial cleaning bones PART 4
There are a few ways to do this.
As bought here. That $26 goes a very very long way so if you plan on sealing a lot of bones or other organics it is well worth the money.
Paraloid is resin-like little nuggets. Soak half a handful in a glass jar of acetone until the chips or nuggets have thoroughly been "melted". The nuggets to acetone ratio depends on how thick or thin you want the solution to be.
You will need a hair painting brush you don't care about; it can't be a cheap plastic brush, the acetone will melt it too. Also, some alumminum foil and make a little platter for the bones you will seal; this is to catch any spills or drops.
First, test how thick the mixture is by dipping your brush into the jar and painting a line on the foil: watch it "dry" (actually the acetone is evaporating and leaving the resin behind)
