Daniel Grandi: Thanks for your discertation as to the advantages of
the Tivac inserts. I am planning on giving them a try. Currently I am
using perforated flasks and can only fit four 4X6 flasks in my oven
at one time. I figured that by using standard flasks with the Tivac
inserts, I can fit nine 4X6 flasks at one time in my kiln. That alone
will make the changeover worthwhile.
I also knock my castings out of the investment when cold to prevent
cracking and also eleminates the need to dry the investment for
disposal. I can imagine that the solid flasks with Tivac inserts will
make knocking out the investment easier.
Thanks again for sharing your knowledge with us. As someone that has
had to learn most of what I know the hard way, I appreciate the
pearls of wisdom that you and others on this list share. Also special
thanks to Hanuman for hosting this website.
