Big Fudge

Hey Guys I just wanted to come back and say I did figure it out! My forge was too small and wasn’t getting oxygen so there was no combustion in the forge but I built a new one which is even better! Thanks for the help

Hello I recently built a new Venturi forge burner due to my old one being unreliable and kinda trashy. The burner works amazing outside of the forge I’ve got a nice strong blue flame with little excess but the moment I put it in the forge I lose that flame and it just starts shooting yellow flames out the side like I’m getting no oxygen. Is it my forge or something with my burner? I will upload some pictures if needed but any basic tips or tricks to play around with would be incredibly helpful thanks guys
