aluminium would melt if anything before the glass.
when i did enamelling silver foil was often used, gold could be, and sometimes copper embedded in clear vitreous enamel looks a lovely pinkish tone. Avventurina glass has its colour because of the copper filings-
Unless its enclosed in molten glass the foil can detach or rub away.

some foils on beads that look gold are actually silver covered with a transparent amber glass colour. obviously gold is more costly.

thin foil works well with glass because its flexibility allows for the expansion and contraction of hot glass cooling down without adding stress.

try holding strip of kitchen foil to a flame and watch it shrivel away ! (but take precautions not to set your home ablaze, please)
