Silicone Measuring Cup

Mixing gypsum in a plastic cup wastes material: the slurry clings to the wall, sets in the corners, and the cup goes in the bin after a few pours. A silicone cup flexes, so the last of the mix comes out in one squeeze, and set residue peels away clean. The dual scale reads in millilitres and fluid ounces, which matters when one product datasheet gives you 100 : 38 by weight and another gives you 3.4 fl oz of water. Heat-resistant to 230 °C, so it also handles warm resin and wax, and the pour spout is sharp enough to fill a narrow mould without dribbling down the outside.
