Are you looking for the individual weight from a wax pattern or are
you trying to determine the weight needed to cast the item. If all you
want is to convert the wax to silver and not cast the item I would
multiply the wax weight by 10 ( approx) and this will give you grams
or dwt depending on the scale you are using. If you want the amount of
metal needed to cast the piece, this is what i do.
1) weigh the rubber base with no wax or tree on it.
2) use a small burr and grind the base weight onto the rubber base so
you will never need to weigh the base again. 3)grind a number onto the
base if you have more than one base. (1 to 100 will do)
4) put your tree (wax rod ) into the base and weld a sprue to the
item you want to cast... then weld this Item to your "tree"
5) Take a piece of paper and label it tree # 1 (if you are casting
more than 1 tree.)
6) Weigh the base with all the parts and the tree,Subtract the base
weight which leaves the wax weight... Multiply by 10 to achieve the
silver weight, then add an extra 30 grams for the button of the tree.
7) in other words...
Total weight - base weight = total wax weight x 10 =silver weight +
30 grams for the button.
- after you have invested your tree, and the investment has
sufficiently dried (1 hr) remove the base and scratch the base number
onto the top of the investment lightly This so you will know which
tree to cast if you have more than tree.
Hope this helps.
