Platinum Casting - Paper liner material


#1

Hi All,

I’m just getting started in platinum casting. Has anybody come
across a common source of paper that can be used for liner in the
flasks for platinum casting.

Is blotter paper a good idea? Also is it a good idea to put holes in
the paper so that investment gets to the wall of the flask? The
instruction on the investment say to use coffee filter paper for the
sprue base with a wax cone. Is there anything better?

Jim,

The Contenti Company in Providence, Rhode Island sells a paper liner
with holes in it just for this purpose, it is called “TIVAC” Paper.
It is pre-cut for 4 inch daimeter and 5 inch diameter flasks from 6
to 8 inches tall. (Item numbers 360-342 and 360-352 with the lower
number being for the smaller size). Their phone number is: (800)
343-3364.

Lane industries specializes in ovens and related materials. They
have a line of sprue bases, liners and all. Designed to help the
water soak out and prevent cracking. Some users of Doc’s who use
flasks use these liners to help get the flask out without beating the
flask to death. Lane Industries LLC 973-209-2046 or
