I have found that a chart as well as investment mixing instructions
usually comes inside my investment container, and I use both Kerr
and Ransom and Randolph investment. Are you using these brands or
Are your flasks unusual sizes? If not, I can fax you my charts which
list the different water to investment ratios for the different size
standard flasks and also for heavy to delicate wax patterns.
There is so much that I will not list it all here, but
anyone can contact me off list and and I will refer to my
manufacturers instruction charts for you, or fax them to you.
