How do you use portal parts? – Junk Jack Review

This game is amazing and all and it’s good as terraria! This game has entertained me for years and it’s so fun to explore! But there’s one question I have, how do you use portals? I’ve been trying to figure out how to use portals but it didn’t work and still don’t know yet and I’m so curious what’s in there. So please let everyone get a hint of how to make and use the portal.
