I don't know what I did. Help (non-emergency)

(from a severe amateur, please bear with me)

I mixed heavy dilutes of sodium tetraborate and sodium metasilicate which created a whitish, translucent gel with water resting on top. Does anybody know what I just made?

Looks like whitish, translucent to me.

In the books it's gold

You probably made silica gel

Borax isn't usually thought of as an acid, but it's more acidic than sodium silicate.
