BZCG = Silicone Bronze Casting Grain, Polished

Silicon Bronze Casting Grain (Polished)

For when copper wants to put on a fancy jacket.

If copper and gold had a very practical cousin, it would probably be silicon bronze.

This polished casting grain is a high-quality silicon bronze alloy that melts cleanly, casts beautifully, and produces a warm golden-bronze color that looks far more expensive than it has any right to. Made from a consistent alloy blend of approximately 95% copper, 4% silicon, and 1% manganese, it offers excellent fluidity and solidification characteristics for reliable casting results.  

The grain form is easy to weigh, easy to melt, and a whole lot more convenient than chopping up random chunks of metal and hoping for the best.

Why casters like it:
* Warm golden-bronze color
* Consistent alloy composition
* Excellent fluidity during casting
* Tight grain structure and good detail reproduction
* Lead-free alloy
* Polished shot helps reduce oxidation before melting
* Easy-to-measure grain form for repeatable results  

Specifications:
* Approx. 95% Copper
* Approx. 4% Silicon
* Approx. 1% Manganese
* Melting range: 1580–1789°F
* Recommended pouring range: 1850–2250°F
* Lead-free
* Polished grain/shot form
* Random grain sizes up to approximately 1/2”  

Bench Reality
Bronze is one of those metals that makes people stop and ask:
“Wait… what is that?”

It has a warmer, richer color than nickel silver, more character than brass, and doesn’t scream “I’m trying to be gold.” It develops a beautiful surface over time and takes patinas, textures, and polishing exceptionally well.

And unlike the coffee can full of mystery scrap metal under your bench, you actually know what’s in this alloy.

A Friendly Warning
Once you start casting bronze, you’ll find yourself looking at every project and thinking:
“This would look pretty good in bronze.”

Unfortunately, you’re probably right.

Warm color. Reliable alloy. Excellent casting characteristics.

A great choice when copper alone isn’t quite enough and gold isn’t in the budget.
