This Nitto Gakku green plastic gauge combines two essential tools in one: A 2mm thick clay thickness guide for rolling, and a ring size gauge. Designed to simplify the process of crafting with precious metal clay (PMC) and art clay, it ensures precise sizing and even thickness during your jewellery making projects.

This tool can be used both to roll clay to a consistent thickness and to measure ring sizes before and after firing. The slots allow your roller to glide evenly over the guide rails, maintaining consistent height while shaping your clay. The built-in circular cut-outs provide an easy and direct method to measure and predict shrinkage in ring sizes due to firing, making it ideal for silver clay, PMC, art clay silver, and ceramic ring design.

Product Data:
• Size: 200mm × 40mm × 2mm
• Weight: 64g
• Material: Plastic
• Package size: 265mm × 65mm × 15mm
• Colour: Green

• Country of origin: Japan

To use as a thickness board, place a slab of silver clay between two boards and roll your silver clay over it to maintain even thickness. To use as a ring gauge, form your ring and check its size against the cut-outs to estimate the final post-firing fit. When used in combination with standard or quick-fire silver clay, sizes marked on the board correspond to expected sizes after firing.

Store in a flat, cool place away from direct sunlight to avoid warping. Do not expose to excessive heat. Clean with a damp cloth after use to maintain clarity of the measurement holes. Not intended for use with high-temperature kilns or open flames.
