Why Gold Leaf Appears to Oxidize in Acrylic Resin Trays
While pure gold does not oxidize, gold leaf can sometimes appear discolored or tarnished when embedded in acrylic resin trays. This is typically due to one or more of the following factors:
Chemical Reaction with Resin Components: During the curing process, certain chemicals in acrylic resin may react with metal impurities in the gold leaf, causing a tarnished appearance.
Moisture Trapped in Resin: If moisture is present in the resin or environment during curing, it can cause metal alloys to oxidize more quickly, especially in thin layers like gold leaf.
Adding the gold leaf after prevents oxidation 😉👌🏻
