Casting a platinum bangle from wax

[Goldfish]

A platinum bangle. With the cooksons wax conversion chart my wax which at the moment is 3gms works out at 64.5g. Which I think will be too heavy and costly.
Just want to check if this is correct? Any good recommendations for calculating wax to metal 🤪

An ambitious project with difficulties likely at every stage.
Using white gold casting grain, or better still, crafting it from Argentium sheet, or wire would be more realistic. Dennis

Yes you are correct It about 65grams of PT. Just find the specific gravity of the metal then multiply it by the weight

It would defiantly be a statement piece !
