Revived from its original 1980s formula, this glaze medium was created to ensure colours remain untinted, even in the lightest passages. Designed especially for whites, light blues , and yellows—where preserving delicate tones is essential—Roberson Original Glaze Medium contains no cobalt driers. While such driers speed up drying, they can subtly discolour pale colours, so their omission keeps hues perfectly clean. As a result, the drying time is longer, but the clarity of light tones is fully maintained.   Safety Data Sheet (pdf) Show more
