Electroforming an Iris Seed Pod

Step 16 Things to look for on the 45 minute check-ups

Pay attention to any points or protrusions on your piece, as they can be prone to a fast build-up, seen here on the tips of the iris pod. If little granules of copper begin forming on your object, turn down the amp/voltage, and make sure the seed pod is at least 2 inches away from the anode.

I often get granules forming on my leadwire before my actual object, but since this is discarded, doesn't pose any problems.

Excellent instructable!  I was wondering what you do if this extra buildup happens.  You talk about adjusting the voltage, but do you have to sand or file the excess down?

I remember reading an article on electroforming and they suggested if one area of your piece is forming too quickly you could use some sort of laquer (sp?) or paint over the area that is forming too quickly. After the rest has "caught up" you can remove the paint and continue electroforming.
