The majority of these pegs have an enormous diameter on one side and a smaller one on the other side, so it is crucial to take out the smaller-diameter sides first. Sashes made later in the century made use of glue instead of pegs. They can be separated by cutting the glue line using an instrument, and then tapping the mortised part loose using a mallet.
