Stainless Steel Pottery Calipers are a very handy tool for potters and ceramists, which are capable of measuring the thickness and diameters of thrown pottery and sculptures, both inside and out.
 
Their easily adjustable compass-like design allows you to take measurements from a model or master piece and compare dimensions against working pieces to ensure consistency in your work.
 
This makes them a very handy tool when creating pottery or ceramics in sets which are required to be a consistent size and/or thickness, e.g. when creating sets of dinnerware, drinkware, or fitting lids
 
Come in 3 handy sizes: 28.5cm/37cm/46cm (after open)
