        Jeshua, Any guess at how much time it would have taken to that core in the 1960 s? Truly amazing technology! Thanks, Rick ... From: hobbicast@yahoogroups.com

            The binder system used for this "printed sand" process is a Furan Resin
            (Furfuyrl Alcohol cured with an acid such as Toluene Sulfonic Acid or Benzene
            Sulfonic Acid). All Furan Resins turn a characteristic green color when
            they are cured.

            Another giveaway that it is an organic resin is the smoke that occurs when
            the liquid metal is poured into the mold (especially from the higher
            temperature iron).

            Sodium silicate would be colorless, odorless and smokeless.
