Code numbering is an essential part of any testing program. This type of stamp is ideal for stamping code numbers and other information on plastic clay test specimens (e.g. SHAB test bars). Set up the run or recipe number on the left and the specimen number on the right. You can find these stamps on Amazon by searching "12 digit rolling alphabet symbol number stamp".

Use this to make length marks in standard SHAB test bars (for testing clay body or clay material drying shrinkage, firing shrinkage and fired porosity). This can be 3D printed. The markers are 10cm apart (outside edges). Most printers can achieve this measurement accurately. To be sure check yours using a caliper, if it is not close to 10cm adjust using sand paper or reprint using an adjusted dimension.
