Fig. 2: Gel composition ((Al/Si)gel ratio) determined from the six leaching experiments conducted on CJ2 glass in pure water (SVj_PW and SVj_PW_GB).
From: The GRAAL2 glass alteration model: initial qualification on a simple chemical system
SiAlNacj2_1 (Al/Si = 0.1273) and SiAlNacj2_2 (Al/Si = 2*0.1273) are the two end members of the gel used to bound the variation in the gel composition through time.
