Saving Four blocks of raw meerschaum

Four various size blocks of Turkish meerschaum. Export of meerschaum from Turkey is restricted, and currently all pipes must be carved in Turkey. These blocks were purchased in Turkey as "sepiolite samples", which is the scientific name for meerschaum. Could be used for saving small pipe projects or repairs, but would be challenging to carve an entire pipe.

Blocks are measured clockwise, starting from the top left, and largest measurement is given.

Block #1: 2.65" x 1.96" x 1.4" @ 1.47 oz
Block #2: 2.55" x 2.34" x 1.4" @ 1.81 oz
Block #3: 2.17" x 1.75" x 1" @ 0.87 oz
Block #4: 1.9" x 1.45" x 1.14" @ 0.66 oz
