Mould Making Resin Casting and Others
Small scale to help me measure the quantities of silicone rubber and catalyst (or A and B parts of the polyurethane resin mixture), in terms of weight (as they're supposed to, instead of in volume). The scale measures a max of 1000g in 0.1g increments. I cost me 7 euro online, cheap and funcional.
I usually make the framming of the mould with cardboard (glossy side in). This way I can reuse cardboard boxes and safely dispose of the leftovers.
Cut out yogurt bottles are used as containers to mix the silicone or the resin. They are made of a plastic that doesn't melt when in contact with any of the A or B parts. Again, a way to reuse, recycle and reduce the amount leftovers.
