Does it take a long/years to turn them purple? How purple will they get?

made sometimes between 1904 and 1912. The purple color will darken slightly if left in the sun for a long long time or you can nuke it (not recommended) under high radiation and it will be a dark purple and considered Fake or altered.

It takes a while to turn purple in full sunlight. It's possible to get to quite a deep purple naturally but it requires decades out in the sun.

Color depends on the amount of manganese in the glass. Naturally turning amethyst takes many years.
