Enamel from Frey Willie

Hello
Just got my bracelet from Frey Willie in Austria. It does not
look like enamel on metal. what is it? thks marie

I just googled Frey Wille and looked at their very colorful enameled
bangles. The vivid colors remind me of the paint-type liquid enamel
that was used on the Diorette floral rings. If anyone is familiar
with the product and the techniques involved, I would so appreciate
the I’ve made some silver pierced pieces that would look
marvelous with color but I cannot use my kiln in my present work area
so classic enameling is not a possibility at the moment.
