I am very new to molding/casting, and have some questions about vacuum degassing. I've seen many videos of people degassing after mixing together parts A and B. They typically do this and then pour it slowly over the object they are molding. Some people have commented about degassing after the mold has been poured. What are your thoughts on this? Is this typical? Do you let it cure in the vacuum? Even after the silicon has settled it still seems to be raised more than when the vacuum is released. Would this effect the mold? Lastly I have thought about degassing A and B separately and then again after mixing. Is this beneficial, or would it be a waste of time.
Thank you! Again I'm super new to this, but very excited. I apologize if I haven't used all the correct terminology. Please correct me if I haven't, I want to learn.
