What is the difference between 'normal' gold leaf and 'edible gold'?
Pure gold leaf is 24-carat. In its pure state it is very soft and delicate and is therefore mixed with other alloys to create different levels of hardness and to adjust the colour tone. That is why most jewellery is 18- or 22-carat gold (mixed with other metals); 24-carat is too soft for daily wear and tear. The same principle holds for gold leaf. If mixed with copper, silver, etc., one can get a wide variety of colours ranging from a slight reddish tone, to bright yellow, to white gold. The alloys mixed in to create these variances are not edible (like copper). Edible gold (mainly 23-carat) is almost pure gold but mixed with silver only, which is edible, so it is completely digestible. https://www.a1mint.com/shop/
