Re: pt/pd mounting > not gum related

You could also get a cracked transparent amber coating by brushing on  
a thick coat of gum arabic and allowing it to dry.   This dried  
cracked coating would be very water soluble, therefore easily removed  
by immersing the print in water, if you ever wanted to take it off.   
But for the same reason, also very vulnerable to water damage.
