How is rosin for string instruments made and what discerns quality?
In: Technology
It is there to bring friction between the bow hair and string.
How it is made is actually quite simple. With natural rosin you simply collect sap trees by tapping them, drilling a hole then putting a tap in so it flows out. Then you distil the sap to collect rosin. Then you heat it to melt it and pour it in to whatever shape you want.
