This is a semi failed but fun hanging concrete lamp. It was originally an attempt to slip cast concrete, which didn't work out so I ended up flicking and smoothing the concrete on. This gives it a rough interior and smooth sleek outer shell which is surprisingly strong but much thicker then the original slip cast that I wanted.
I am new to concrete but am loving it so if anyone has ever done any slip casting with concrete I would love some tips.
What you need:
ABS styrene 2.5mm
sand (fine grit)
small piece of foam core
Step 1: Cutting the mold
Print the two lamp guide templates onto A3 paper, and cut them out.
Tape them down to your 2.5mm ABS styrene.
Cut around each piece. You should have 5 pieces.
