This is my way to prepare the size:

200 gr. parchment clips which were cut to 1X1cm., to be left over
night in a gaza cloth (or any other light cloth) in a tap water
container. Remove the parchment from the container throw away the
water. Put the gaza with the parchment and 1 liter tap water into
double-boiler and heat it up to 85 Celsius for 3 hours. While
heating it is recommended to stir once in a while the gaza with the
parchment clips, you can add some water to the "soup" to keep the
same water content 1 liter. Now you got the parchment size, when the
//zise gets cooler I filter it to remove impurities and  since I don't
use this quantity at once I use plastic sacks for ice cubes (for ice
cubes home made) and I freeze it, whenever I need some size I use
the microwave to defrost the size to liquid state.  Good luck,
