Getting a flawless silver ingot doesn’t have to be a guessing game. 🌪️🔥
Here is my quick 4-step routine for a perfect, pit-free pour every single time using the KC Ingot Mold:
1️⃣ Prep the mold: A quick coat of Boron Nitride spray is the absolute game changer here. (Don’t forget to wipe the flat surfaces afterwards!)
2️⃣ Angle it: Tilting the mold lets trapped air escape easily—say goodbye to annoying pits and porosity.
3️⃣ Melt it clean: Add a pinch of borax! This flux acts like a protective liquid glass shield over your melt. It binds existing oxides and prevents new ones from forming. Keep heating your silver until it reflects like a mirror with zero crust.
4️⃣ Temp check: Slightly pre-heat the mold to get rid of any trapped humidity and to avoid thermal shock. (Pro tip: If your metal ever spills or splashes out during the pour, your mold was likely still too cold. No stress—just remelt and try again!)
The result? A perfectly clean, solid ingot that is instantly ready for the rolling mill!
🔍 Quick Pour Troubleshooting:
❌ Mold not completely filled or not a perfect cylinder? \rightarrow Your melt was a bit too cold.
❌ Large, rough crystals visible on the surface? \rightarrow Your melt was too hot. Try to dial back the heat a bit next time!
