In my case it soaks in around 2mm below the ceramic board surface , it is possible to fully soak ceramic matting.

Wouldn't soaking CFB in waterglass fill the air gaps between the fibers and result in the loss of most of it's insulation properties? A valid concern for sure. A sample I cut open was still fluffy in the middle. And I accept some loss of insulation for what I gained in abrasion/fraying resistance with the super soft CFB I had. Especially since my riser stub is 3 inches thick. I have no doubt the pros and cons of waterglass would be weighed differently with a better quality CFB. I just know I wouldn't have been able to use this poor quality CFB at all without it.
