Hello Carboneers,
My question is like Joao's. I used the same method. I had a glassplate over
a hot waterbath so that the temperature of the glassplate was around 43 C.
In my sens the gelatine solution can even out. Is that to warm ? How warm
should this be.
The paper for the tissue was before soaked in water and squeezed. To get it
loose from the glassplate after pooring gelatine on it I pushed a colder
glassplate in between the hot one and the paper. The gelatine should set by
this action.
Well, it did not work out very well. It looked like I had used Seven Up in
stead of water for my gelatine solution. (An advantage of Seven Up is that
you don't have tu use sugar in the formula) and I found it difficult
spreading the gelatine solution with a rod, finding the thickness of the
coating.
I will be back.
Witho
