Query: useless in no time

How come the Pyrex and Kimax labware I have will keep the graduate marks on them through hideous chemicals and severe dishwashing and the Pyrex measuring cup for my kitchen lost ALL of its markers after 2 trips through a HOME dishwasher?I bought this because the 55 year old one from my mother had lost all of its markings. Now this new one is just as useless.
