| Sourcing | This color is sourced from actual gold. To be more precise, the gold we find in food has the chemical composition of 961.5‰ Au (Gold) and 38.5‰ Ag (Silver), hence the dye is created from pure 24-carat gold which has a minimum of 99.99% certified grade of gold. |
| Manufacturing | To create this additive, the sourcing material typically first comes in thin sheets (thickness of which is one-tenth of a micrometer). The sheets are milled (typically by a mechanical mill with a particular kind of mountable grids) to reduce the size and, based on the exact need, create crumbs, flakes, or powder. Manual cutting with a knife is used if the creation of perfectly squared leaves is necessary. For the unsquared leaves, these are kind of a by-product of the milling process and can be simply extracted and used. For the purposes of purification, the gold gets heated to about 100°C for a duration of at least 2 minutes. |
