This is my note and video about aluminum saucer casting. I use the same sand molding technology as in my previous videos. If you're interested in more details about green sand casting please read as well my other instructables and watch videos such as "Clothes hook - Aluminum casting" and "Brass casting heavy paperweight". Now, I'll mention just the main steps.

Step 1: Making a Mold
I used a ceramic saucer as a pattern.
Step 2: Casting Aluminum
I always have the problem with the quantity of melted aluminum. This time I prepared much more than was needed. Some aluminum got on the flask but it wasn't a problem.
Step 3: Taking Out the Saucer
When aluminum had cooled I opened a flask and took out the saucer.
Step 4: Finishing
Cut off technological metal and sanding the surface.
