Introduction: Pewter Sand Casting
There are many ways of pewter casting with a lot of different molds. In this tuttorial I show you a casting method with molding sand. It's a fast way to make a sand mold for pewter casting, but you can only cast one time. After casting you can use the molding sand again to build a new mold. In 10 steps I show you how to make a copy of a small plastic doll with pewter.
Step 1: What Do You Need?
What you need:
- Old saucepan
- Gas burner or hotplate
- Molding sand
- Short PVC tubes fitting into each other
- Wooden spatula
- Rubber hammer
- Hobby knife
- BBQ skewer
- Plastic doll
Step 2: Filling With Sand
Fill the bigger PVC pipe with molding sand and pressure with your hand. you can beat lightly with the rubber hammer for better filling.
Step 3: Place the Plastic Doll
Push the plastic doll in the mold and ensures that it adheres well everywhere. you can use the back of the brush to push the edges.
Step 4: Talcum Powder
Cover the surface with talcum powder and spread it with a brush. This prevents the two mold parts do not adhere to each other.
Step 5: Second Half of the Mold
Put the second half of the mold in the first half and press lightly. Put a stripe on both halves so that you can put them back in the same place.
Step 6: Filling the Seccond Half
You know how it is to fill but be very careful with the rubber hammer.
Step 7: Remove the Plastic Doll
Remove the plastic doll carefully with a hobby knife and prevent your mold damage.
Step 8: Create a Pouring Channel
create a pouring channel with the back of your brush and a BBQ skewer. Make sure the top is wide enough to pour in.
Step 9: Melt the Pewter
The melting temperature of pewter is 230 degrees celsius. Within 10 minutes on my stove the pewter was melted. You can remove the dirty film on the tin with a wooden spatula. And use a spoon to stir in the pan, if necessary. When the molten pewter is good you can start casting directly from the heat.
Step 10: Final Result
Remove the pewter doll from the mold after 10-15 minutes, because cast pewter is very hot. You can use the molding sand wich is not burned for a new project. Now you can sand and polish the pewter doll for a beautiful finish!
