A ceramic powder for a ceramic component, in particular based on zirconia and/or alumina, in particular for a timepiece or jewelry piece. The powder includes at least one noble metal among platinum, rhodium, osmium, palladium, ruthenium and iridium, at a quantity of less than or equal to 5% by weight.

A pressurization device includes a body, a shaft, and a stopper. The body includes a setting section and an insertion section. The setting section is configured to accommodate an object to be pressurized. The insertion section includes a female thread part formed on a hole wall thereof. The shaft has a male thread part. The shaft is configured to advance and retreat with respect to the setting section by rotation. The stopper is configured on the shaft. The pressing part is configured on a first longitudinal end of the shaft to press the object in the setting section against a prescribed fixed part when the shaft advances. The handle is configured on a second longitudinal end of the shaft to rotate the shaft. The handle includes a torque limiter being configured to block transmission of power between the handle and the shaft when the power exceeds a prescribed amount.

A Brunnian link is a link formed from a closed loop doubled over itself to capture another closed loop to form a chain. The example kit provides for the successful creation of unique wearable articles using Brunnian link assembly techniques and includes several pin bars that are supported in a desired special orientation by at least one base. The desired special orientation is dependent on the desired linked configuration of the completed article. The pins may be assembled in various combination and orientations to provide endless variation of completed link orientations.
