Yes they can. The molds from the 1962 Vac-u-form are the same as the 1964 Thingmaker/Creepy Crawlers molds. Wait, only if you are talking about the metal molds, don't put the plastic molds on the Thingmaker oven. The metal molds will work in the Jakks light bulb style ovens too but the tongs they give you wont fit on the molds so you will have to use a spatula or something similar to fish them out. Did that answer your question?
