I made a sample engagement album or it can be used as a guestbook. That's how I saw an example of it and I loved the idea. It needs to be signed with a silver pen.
These are concrete samples taken from building sites - they are stored for either 1w/1mo/3mo and then tested for strength. If test fails, construction must stop, building taken down, and some heads may roll...

I made several samples to try to decide which bottom fabric I wanted to use and how I wanted to cut the top fabric. I ended up going with the bottom right pattern. It's a dusty bottom fabric that I bought on sale at Alabama Chanin a few months ago.
A carbon nanotube sample ready for measurement. The yellow chip carrier is approximately 11mm wide. This was the first time I experimented with focus stacking (5 photos).

Pushing the Boundaries of Plain Weave. Workshop with Jane Stafford. Hosted by the Greater Vancouver Weavers & Spinners Guild on March 20 to 22, 2009.
Sample in UKI mercerized cotton.
This 5-mm-wide sample holder features a flat platform for attaching a sample of material, surrounded by three suspended chip sensors that are connected via gold wires to the sample. The sensors include one heater (white in appearance) to supply heat to the sample, and two thermometers (gold in appearance) to measure that heat as it travels through the sample. This sample holder was designed and assembled by Shermane Benjamin.

Corundite (emery rock) with corundum/sapphire (blue) and calcite (yellowish-brown). (broken surface, dry)
Corundite is a remarkable metamorphic rock. The sample seen here has an attractive bluish color and wisps of yellowish-brown. Its composition and origin are quite unusual. Corundite (also known as emery rock) is dominated by corundum, a very hard (H ≡9) aluminum oxide mineral (Al2O3). This particular rock has blue corundum, therefore it can be called sapphire. Rock-forming corundum is rare.
This material comes from the Naxos Emery Deposits on the island of Naxos in the Aegean Sea. Naxos is dominated by metamorphic rocks and some igneous rocks. Much of the island consists of marbles (originally limestones). Some of the original limestones had lenses of bauxite, which is a rock having aluminum hydroxy-oxide minerals. Upon metamorphism, the limestones were converted to marbles and the bauxites were converted to diasporites (= diaspore (AlO·OH)-dominated rocks).
Upon further metamorphism, the diasporites were converted to corundites plus water. High fluid pressures fractured the rocks, and the fractures got filled up with corundite.
Metamorphism on Naxos occurred during the Cenozoic in two main phases. A high-grade metamorphic event occurred during the Eocene, at about 40-50 million years ago. A second, intermediate-grade metamorphic event occurred during the Early Miocene, at 16-20 million years ago.
