Our glass is carefully sandblasted and does not require a color fill. Color does improve readability, however, which may be an important consideration if you plan to have a photo shoot or need the award to hold a lot of text in a small point size. We offer silver or gold metallic fill that has a carnauba wax base, but some petroleum content (view MSDS). The fill is applied by hand after the glass piece is sandblasted. The fee for color fill is $10 per piece. To request fill for a glass product in our store, choose the fill color from the dropdown menu on the product page. The price will update automatically.
