We are looking for ideas on how to add a patina to pewter...we are wanting a gunmetal grey type colour. I have read that a dulted solution of nitric acid will work, has anyone tried this. I have picked up some Lime sulphur to try but i believe that will give an antique effect. Thanks Peter  Pewter patina

We cast lots of larger pewter figurines and then sprayed them with liquid graphite. After that dried, we would buff off excess to leave dark area in recesses to add to the relief. Acid followed by a baking soda wash to stop the reaction works, but is messy. Aerosol graphite is easier to control. pewter patina

Most pewter casting operations use the spray on graphite, rub off excess, then wax for their production. There are "true patinas" for pewter but as stated, the acids are a bit of a "problem" especially when you can get the consistent, non reactive and not dangerous "patina" with the graphite materials............. John Dach Thanks for the idea's...we

Thanks for the idea's...we are trying to produce pewter countertops so need something permanent and durable...I tried spirits of salts today, a weaker solution of hyrochloric acid...this worked pretty good and exposed the creases in the sheet that occur when the sheets are rolled, also left a pitted suface that gave it an aged look.

Pewter Patina
I tried to patina pewter with my standard patinas and got no where. The colors just rubbed off. You might contact Lisa Slovis Mandel for she has just published a book called the Pewter Studio. Her web site is www.lisaslovis.com . Hope this helps. Let me know what you get to work for I would like to try it.
