The double ended caliper is a precision tool used in ceramic modeling to measure and compare dimensions of a piece at any stage of its creation process. This instrument, with two curved arms that can be adjusted to cover the diameter or thickness of a piece, is indispensable in both handmade and industrial ceramics. It can measure wall thicknesses, internal and external diameters, and depths, ensuring that pieces have uniform proportions and meet the intended aesthetic or functional requirements.
When throwing, the double ended caliper allows accurate measurement of mouth diameter, wall thickness and base size, ensuring symmetry and consistency in repetitive designs. It is also used in the finishing stage, where dimensions are checked before firing to ensure that parts fit correctly, as in the case of matched lids and containers.
Interesting Fact
In traditional Chinese ceramics, calipers made of bamboo were used to measure the dimensions of delicate porcelain bowls, ensuring the perfect symmetry that characterizes these pieces.
Helpful Tip
When measuring parts during throwing, regularly check the dimensions at different points to detect any irregularities and correct them before the part dries.
