As stated I have been using X-Vest investment powder for all of my learning journey. I am sure it is great for some people. But not for me anymore. I ordered a new investment to try out and I can’t believe how much time I have wasted!!!!
The problem with X-Vest was that it is super hard after the burnout and does not come off the casted object easily. I had to scrape for 30 minutes using all kinds of tools to get the cast out of the flask and clean the model.
This is now history. The new investment powder is made by: Certus and called “Optima Prestige” (link). It mixes easily, the casting surface is very detailed and smooth and to get the model out of the investment after casting, all you have to do is quench it in water after a cool-off period of 15 minutes. When quenching the investment is magically flying off the model and there is very little and easy cleaning left. What a relief!
