VOUSSOIR - KEYSTONE MIXTURE 10 mm

70 miniature voussoirs, 10 mm length, obtained from the mixture of three different clay types.

11 well fitted voussoirs draw an approximately 23 mm inner size and 43 mm external size semicircumference.

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.
