Investment to water ratio


#1

Dear Orchidians, I have searched the Orchid site but couldn’t find
the following info so i thought I’d ask and see if anyone can answer
my question. I have some small flasks and i do not know the
investment to water ratio for them. I am using Westcast investment
and they have a chart listed in the rio grande catalog but I am not
sure how to determine the flask sizes for the ratios. I have 4 sizes
i need to know about. The Flask sizes are 2" X 2 1/2", 2 1/2" X 2
1/2", 2 1/2" X 3" and 2 1/2" x 4" And lastly, how long do you have
to wait for investment to dry before you dewax with a steam dewaxer?
If anyone has this info I’d greatly appreciate it! Thanks so much!
Tai
