Basic research on the formation of monolithic glasses from metal alkoxide has been done concerning gelling of silicon alkoxides and dehydration of those gells. The felling time were increased with increasing of Carbon number of alkyl radical of alkoxide and am-ount of water and the lower pH value of water. Large portions of water and organic materials were rem-oved below 25$0^{circ}C$ and shrinkage of glass took place above 80$0^{circ}C$ Therefore heating up to 25$0^{circ}C$ and above 75$0^{circ}C$ must be done gradually with rate of 0.5$^{circ}C$/min.
