Ikea Genomsnitt Scale
There are a few tools which seem to be more versatile in the ceramics business than a scale. I originally purchased this scale from Ikea so I could weigh my clay in an attempt to make pieces more similar in shape. Starting with the same size ball of clay has done wonders for my craft; possibly even a borderline superstitious obsession but, has no doubt assisted me in improving my technique over time. By taking the same amount of clay and seeing how far you can stretch the walls up without making them too thin, or working on making sure the clay makes its way from the bottom to the top in nice even lines. It's all part of the craft and can be both magical and defeating.
I did however, end up using my scale for many more things including weighting out glazing materials, weighing my finished pots for online sales/shipping costs. I also used my scale to take measures for pricing out my pottery by documenting the amount of glaze and clay each piece takes. This particular model is just one smooth surface, which means it's easy to clean, and the digital scale in both pounds and grams is especially useful.
