Lost Wax Casting Step 7 of 9 Cleaning the newly cast charms

[supperstorm]

What kind of wax they use? can you make your own wax?

Very Good presentation. Easy to understand.

If I used gold as raw material, is the cleaning process remain same ?

[FeatheredGems]

The cleaning process is the same, but not the finishing/polishing. You would need a good dust collector on your grinder to save up the gold you grind off the castings.

well, if it's just citric acid, it would be enough to just rinse it with water, shouldn't require drastic measures as neutralizing.

for example, technically used acids (phosphoric,nitric, sulphuric, clorhidric or muriatic) are dangerous even when diluted, hence the necessity of neutralizing.

...but rules are rules.

good educational series though

I know I don't HAVE to neutralize citric acid. But I do because my castings go from pickle into the ultrasonic. don't want to keep dripping a little acid into the ultrasonic tank with every casting I add.
