1 - Smooth-Cast® 325 casting resin, So-Strong® Black tint and Bronze powder are combined to make a 'Cold Cast' Bronze Casting. Any metal powder (-325 mesh) can be used including copper, brass, nickel/silver, etc.

2 - Equal amounts of Smooth-Cast® 325 Part A, Part B and Bronze power are measured by volume.

3 - Two drops of So-Strong® Black tint are added to Smooth-Cast® 325 Part B and thoroughly mixed.

4 - Combine Smooth-Cast® 325 Part A......

5 - Smooth-Cast® 325 Part B....

6 - and the Bronze Powder into a mixing container and mix thoroughly.

7 - Continually scrape the bottom and sides of the mixing container while stirring to keep the metal powder from settling on the bottom.

8 - Pour the liquid into the center of the mold cavity. Silicone rubber works best for this application. This mold is made of Mold Max® XLS silicone rubber.

9 - Immediately begin brushing the material around the mold cavity creating a 'gel coat'.

10 - The mixture will continue to thicken as you brush. Once you feel the material starting to ''gel'' or ''stick'', stop brushing. Over brushing will result in a damaged casting. After brushing, let cure for 5 minutes.

11 - Measure equal amounts of Smooth-Cast® 325 Part A and Part B by volume. Add a few drops of So-Strong® Black tint to Part B and mix.

12 - Combine Smooth-Cast® 325 Part A with Part B in a clean mixing container.

13 - Mix the material thoroughly, scraping the sides and bottom of the container several times.

14 - Pour the liquid into the center of the mold cavity until full.

15 - Allow the casting to cure for a minimum of 60 minutes before removing from the mold.

16 - Finishing Stage: For best results, Mineral Spirits, medium/fine steel wool, and shoe polish are used to bring out the most realistic metal effect.

17 - Begin by wiping down the entire surface of the model with a towel soaked in mineral spirits.

18 - The mineral spirits will soften the plastic slightly and make it easier to bring out the metal shine when buffing with steel wool.

19 - Abrade the casting using medium/fine steel wool until the desired metal shine and luster is attained.

20 - Highlight the surface with black shoe polish to add depth and dimension.

21 - Allow shoe polish to dry then buff with a soft cloth.

22 - To prevent the oxidation of the metal, spray the polished piece with two coats of semi-gloss acrylic spray.

23 - Finished Cold Cast Bronze piece.
