Pink Bronze Patination

 

Description

Very delicate coloured bronze patination. The key to this patination is in the application of the main colouring solution, a very subtle patterning can be achieved in its application. The patination is durable if well sealed and remains stable if well maintained. 


Metal Preparation

Silicon bronze sanded to a even 120 grit
 


Colouring chemical solution

Water ----- 250 ml
Medium Bismuth Nitrate Solution ------ 1 teaspoons
Titanium Oxide ------ 1 teaspoon
Red Iron oxide ----- 1/2 teaspoon
Additional Fixative ----- Weak sodium silicate solution
* Leave solution for 24 hours, this helps the bismuth completely dissolve.

 

1st Colourcoat Application

Heat the bronze evenly, the solution should just sizzle and evaporate away as you apply it with a natural haired paint brush. For this particular patina, we wanted to achieve a delicate patterning in the patina, so we used a small no. 6 round brush for application. This enabled us to apply very small amounts of solution onto the bronze at each application. This helps with the control and how the solution disperses on the hot bronze surface. The oxide pigment mix that forms on the surface of the bronze, should be developed slowly in thin layers. Let the solution settle out for a lightly washed out colour and for a stronger colour keep the mix stirred as you apply. You can use this method to develop a greater patterning or contrast in the patina. The resulting patina is visually very delicate, with a small amount of variegated but even patterning across the entire surface.  

 



Sealing Solution

Sculpt Nouveau Smart Coat - 1K Polymer Sealant


Application

When the bronze is at room temperature, we use soft cloth or brush to apply 3 coats, letting them fully dry between applications. 

Highlighting

To add additional colour to highlight areas, we mix a small amount of pigment with a small amount of sealant and use a sponge or brush to add this mixture.

Darkening Shadowing

To create shadows or to darken areas we use a graphite wax, this is thinned down with a clear wax to create a translucent paste. This is applied both under final wax layers or over the final wax layers.


Final Wax layers

We use renassiance wax for the final waxing. Its applied with a soft brush in a very thin layer, left for 10 mins and buffed to a hard finish. We add three or four layers, with the final layer buffed to the final finish.
