With such a push against single use plastic and mirco plastics etc. Why is glitter left untouched? surely it has to be one of the worse plastic pollutants. Currently getting our Christmas shop ready, and its on everything and gets everywhere!
Edible glitter already exists. Iβd have to imagine that it is also biodegradable.
I wouldnβt think it would have to be biodegradable, just inert and non-poisonous
You certainly can with mica. The downside is mica mining has definite links with child slave labour depending on the source, so, not as fun as hoped. https://brewglitter.com/collections/whiskey-liquor-glitters
