Sometimes, Insects Decide (Decidere di Insetti)

This past Friday, I had received a shipment of an extraordinarily expensive and rare stone from Rome to use in an art project. It was the legendary 'imperial porphyry' from ancient Egypt. Until locating this sample I was considering using a substitute stone from Trentino Italy, but that one was less brilliant red / purple and the white specks (phenocrysts) were less perfectly white. Since all of my other 'ingredients' were the authentic originals, using the lesser stone seemed like a compromise that shouldn't be made.















In order to make the work look authentic as the 1700 year old original pictured above, I tried to talk myself into breaking the center circle and putting it back together again. But, I kept thinking about the rarity of the stone and how I would be smashing (temporarily) something that costs so much. It was like when you are about to jump off a high-dive platform for the first time and the voice in your head is talking you out of it.

Yesterday afternoon, I carefully drew off the perfect 7" (17cm) circle, I set up my diamond saw outside with a 0.25mm (tiny) blade to avoid material loss of such a precious material. I worked intently, keeping my fingers out of harm's way (the blade is tiny and somewhat flexible since it is so thin).

The wind in Texas has gusted very strongly for the past few days. But despite the wind, about midway through one of the cuts to shape the expensive stone, a yellow jacket wasp bumped up against my leg. I tried to shoo it away with my foot, but it was not having any of that. It kept aggressively buzzing around.


















It flew at my face on a final attack dive bombing run, and I had to concentrate on not losing fingers while this happened. Jumping back, but with hands away from the blade, the stone flew off the saw table and landed on the cement where it broke into three pieces. Satisfied with the mayhem it had created, the wasp flew off happily.

I pieced back together the rare stone pieces and finished shaping the perfect center circle. Sometimes, things work out just fine, don't you know?

Hooked on Sardonyx (Affeto Sardonice)

It's a cloudy dreary chilly day in Dallas, which is fine because it all goes well with my mood today. Downtown, the streets are filled with people on their way to lunch.



















I've just ducked into one of my favorite places called Porta di Roma, a Chinese takeout place. Just kidding, it's Italian food. The name means 'gateway to Rome', but no matter how many doors I open here I can't see Piazza Navona through any of them.

The food is really authentic and the view is great because it's directly across from Neiman Marcus, the famous high end retailer. People watching is at its best in Dallas here. You can see millionaires pull up in chauffeured stretch cars, or maybe a homeless guy wearing a baseball cap with wings slowly pushing a shopping cart with watermelons dressed like Cabbage Patch Kids (tm).

As for myself, I need to stop back into Neiman Marcus today because:
a) my personal shopper there has rent due soon and keeps tweeting me
b) they finally have their secret cookie recipe for sale as in the urban legend, or
c) I want to see if the sardonyx bowls that were full price last year on sale now

As is the case when taking tests, 'C' statistically is the right answer.

Sardonyx is a type of onyx / calcite with just the right red / brown colorations that nice sconces and lighting fixtures try to copy with patinated glass. But, this is the real mineral deal that was used for thousands of years and usually worth more than gold.

In Venice, in the treasury of the San Marco cathedral, they have wonderful sardonyx treasure cups taken back in the fourth crusade like this one with the lower section in the rare stone.


















Going back further, first century Romans created great works with it as the cup of the Ptolemies and 'Great Cameo of France' below.




























I'm kind of a sculpture guy first, so you can understand my appreciation for a material that is so workable like this from a carving standpoint, and also has such beautiful color and translucency.

Some nice sardonyx sconces are called for in my media room. It's probably not a good idea though to just hang the Neiman Marcus bowls on the wall with duct tape and bailing wire? I think they were $11,000 last year.
