VOUSSOIR - KEYSTONE MIXTURE 6 mm

70 miniature voussoirs, 6 mm length, obtained from the mixture of three different clay types.

12 well fitted voussoirs draw an approximately 28 mm inner size semicircumference. External size is 40 mm.

Hardness of these voussoirs is adequate to allow modellers adjust to the limit each single piece to the adjacent ones with some sand paper.  Even the semicircumference diameter can be modified this way.

5 mm thickness allows the voussoir combination with diverse stones with the same thickness or thinner.
