You put glue and water.
Back then they might have used a plant to make glue if they knew about glue but today I think we make glue with chemicals.Simple paste can be made with flour and water.
No , the glue will not apply smoothly and will not make a lasting joint.
Water will thin white glue and at some point make it useless.
Using hot water to make glue solution can help in making the glue easier to apply due to the lower viscosity. However, the strength of the glue bond itself is determined by the properties of the glue and the surface it is applied on, not just the temperature of the water used.
NO!
Rip up paper into small pieces, soak in the water and stir it, then add the white glue.
If you water any glue down, you simply make it weaker, with less adhesive effect.
