How do you take care of a France Cast?

As casting technology has evolved, our replicas have evolved through three basic materials. We began in 1986 with replicas made of plaster impregnated with polyurethane. These were detailed but fragile. We then made casts in epoxy, which was much more durable, but dangerous and difficult for us to pour and trim (though safe in the final product). We are currently using a resin that is safer for us, and gives incredible detail in a durable cast.


If you own an epoxy or today’s resin cast, you may clean the cast with soap and water or mineral spirits. Mineral spirits may remove some of the oil paint wash used to accentuate detail, but it will not harm the cast itself. You could even put the casts in a dishwasher (ok, maybe you don’t want to do that, but you could!).

If you own a plaster cast, you may clean it with a damp cloth using a cleaning solution (like Orange Clean or Windex), but do not soak the cast. Plaster is reasonably strong when it is cured and dry, but it weakens when wet. If your cast gets very wet, just set it aside and let it dry.


Even though today’s resin cast is durable, students are experts at blunt force trauma to teaching materials, and accidents may happen. With any broken cast (plaster, epoxy, or today’s resin), use 5-minute epoxy for the repairs. If you wish, you may use Super Glue on the epoxy or resin, but it doesn’t work very well on the plaster.

If you would like us to repair the cast, give us a call!
