For modelers who make room-temperature vulcanizing (RTV) rubber molds and do resin casting at home, convenient measuring and mixing containers are a must. A great source of such containers can be found in the laundry room – the clear measuring caps that are provided with detergent. They come in various sizes, and many have simple measuring marks on the side that can be used to measure the proper ratio of RTV or resin. They are made of a chemical-resistant plastic which can be easily cleaned of cured RTV by peeling, or resin by gently flexing the container.
