Vitreous, vitrify

Vitreous (adj): resembling or containing glass.
This word comes from the Latin root “vitreus” which means “glassy, transparent”. This root in turn is derived from Latin root “vitrum” which means “glass”. A term which is cognate to this root is “in vitro” which means “in glass”; you may have seen this term in relation to “in vitro fertilization”. Well there are two types of fertilization: one is “in vivo” (in the living system, in the life form) and other is “in vitro” (as the fertilization is done in Petri dish which is made of glass.)

Vitrify (V): convert into glass or a glass like substance by exposure to heat.
People you might have heard about a particular type of tiles that are quite famous these days, by name “vitrified tiles”, they are called so because they undergo a process called as “Vitrification” which gives them a shiny, glass like appearance.
