Sterling Silver granulation

 John suggested coating the granules with saliva helps them
adhere to the surface and fuse more easily.  

I never heard of this for granulation…but when I learned the
kumboo technique, I was taught to use saliva help the gold foil
adhere to the surface and to aid in fusing. So…who thinks that
there might be some scientific proof behind this and why?
Burgess? anyone?
