I don't think there are gold ink for pens, but I hope there is a chance for dip nibs. For decorative touch ups and greeting cards it can be nice.

I have a bottle of "Royal Talens Ecoline 801", but it's very difficult. I have a few dip nibs, not a that many to choose from. Is there a special nib for thicker inks? Is there are more well behaved gold ink available?

At the moment I am just playing around with deep reds, colors and metallic inks to improve my skills.
