The company started in 1930, with clays. Then they made "canicas de cristal", which I presume to be clearies. Then in 1944 they made "Trébols”, which would be cat's eyes, and that may have been before Japan started making cat's eyes. (Someone may correct me with more up-to-date information.)
The Vacor swirls may have started being made as early as the 1980's, but definitely were in production in the 1990s and still are to the present. The Galaxy/Planet style is from the 1980's and still made later.
They made some stunning marbles in the 1960s. Here is an example posted on Facebook by Ricardo Mendoza. Style name: Mosaico
