Finally, after a lot of procrastination, and dealing with the
unfounded fear of my vacuum, I am finally ready to do the vacuum
casting. I still have a question, before I attach all the sprued
models to the flask bottoms, and get ready to invest.
I have weighed each model and its sprues. multiplied the weight by
10.4 grams, then multiplied that weight by 1.33 to allow for the
button. So far so good.
Now to my question. I will be casting 3 rings in each flask. For the
button, do I add the full amount of the extra (1.33) figured foreach
model This seems to me to be too much silver as I only have the one
botton. Nothing has changed except that instead of attaching one
sprued ring to it, I will be attaching 3. The wax button Is the same
size and weight as for one ring. I was wondering ifthere is some
formula or rule when casting more than one item in the flask.
Thanks for all your wonderful help. Alma.
