I have seen posts about casting blanks and it appears that some folks do it in a pressurized environment and others prefer a vacuum and there may be some who use neither? So here is a poll to see what technique is preferred.
I use poly resin with different kinds of dyes i have not yet tried to cast any objects in resin so i dont know how it would work without a presure pot but when i do i'll let you know.[][]
I checked neither. This is because I use pressure on specific things and vacuum on other things. It's not whether I prefer one over the other, It's which one will do what I need it to do.
