The raising looks great. Nice ripple effect from your hammer stroke patterns. Can you show us your home made stake? Bob ![]() Way to go

Lorrie, Are you going to plannish it some more or is your arm wore out? If you do not want to mess around with the sawdust, just wrap in saran wrap. www Metalrecipes -- heat and beat to the desired shape, repeat as necessary. ![]() Plannish?

Ah-well I guess the answer would be YES, since the apprentice is still learning. Thanks for the great teaching. I have a long way to go. Would like to just get one completed that looks good. I'll try both processes for the patina. I have another one I am working on but it has a very rippled/wavy effect about 1/3 of the way done. Should I try to plannish this to flatten it out a bit, or just keep pounding on the ripples as I travel along the rows? It's getting hard to follow along the rows with the metal raising up right where I need to pound it down (if that makes any sense at all). ![]() Sure

Lorrie, maybe switch to the other hand to hammer with, grin. www Metalrecipes -- heat and beat to the desired shape, repeat as necessary. ![]() Lorrie, Looks to me like

Lorrie, Looks to me like you're doing fine! After every series of raising, you should bouge the piece thoroughly with a rawhide mallet over a stake. Do this with all the force you can muster - really whale the hell out of it! This evens out the stresses, knocks down a lot of the ripple effect and gives you a better place to start when doing the next series. Occasionally, when I'm raising in copper (which is really soft), I find that one course is more pronounced than the previous one. If that happens, then I will bouge a bit before i go on to the next course. Generally though, I just do all the courses for the series, bouge the piece, anneal and start the next series. If the bouging after raising didn't even things out enough to suit me, I might bouge lightly after annealing, too. Hey, raising is a process that looks really rough until you get almost finished, sometimes. If you do the narrowest possible courses and only move them a moderate amount each time you can have a piece that looks less lumpy while "in progress", but you'll take a lot longer to finish it, too. I'm impatient so I whack away, bouge a lot and keep it moving as fast as I can. I usually get away with it. (grin) Rich ![]() Thanks Rich, I can't wait to

Thanks Rich, I can't wait to learn more about this process. My next big adventure will be to try and tackle a type of vase. Not sure what kind of tools needed for that. ![]() The same basic tools,

The same basic tools, Lorrie. Stakes and hammers. You may need to find or make a stake that has a curvature to match the vase so yo can get it inside the mouth of the vase when the raising progresses to that point. For some really good information on raising, I would commend to your attention the book "Silversmithing" by Rupert Feingold. Rich |

For patina I would check out the description of bury patina written by Claire Sanford in Metals Technic published and edited by Tim McCreight.
I have used 1cup water, 1cup household ammonia, & 1Tbs of salt. Dissolve salt in water and add ammonia outside with lots of ventilation. Wet sawdust/pet bedding until it can be squeezed in your hand without wringing any drops and yet it can leave a wet spot on a sheet of paper.
Bury the metal in the sawdust and seal the container. Check it after 3 hours and then every few hours until you get the result you want.
Best,
Fred
