So my understanding of using Glass Cast 50 is that the maximum thickness you can cast is 25mm in wood. I am assuming this is for river tables where there is wood on two sides and potentially some on the base.  However it states that you can cast upto 50mm in moulds.
So if  I am pouring into a mould with wood on just 1 side then  technically i can pour thicker than 25mm? I am only looking for about 32mm but would like to do it in one pour. 
Any thoughts?
