The bad news - A very large piece of metal that I need to continue with No.7 has been on backorder for 3 months.
The good news - This forces me to take a break from the marathon project, and make some smaller pieces.
This one goes on sale this Tuesday at ericfreitas.com
Tucson, AZ visiting Jelena and Neil. Someone was using this as the landscaping rock on a hill in their backyard.
Alpenglow in the morning (5 AM) and already too late in the day for our 2002 attempt on Quartz's east face. In 2004 we came back and got up at 2 AM, summitted in the early afternoon, back to the tents at 11PM that night.
A mineral is a naturally-occurring, solid, inorganic, crystalline substance having a fairly definite chemical composition and having fairly definite physical properties. At its simplest, a mineral is a naturally-occurring solid chemical. Currently, there are about 5400 named and described minerals - about 200 of them are common and about 20 of them are very common. Mineral classification is based on anion chemistry. Major categories of minerals are: elements, sulfides, oxides, halides, carbonates, sulfates, phosphates, and silicates.
The silicates are the most abundant and chemically complex group of minerals. All silicates have silica as the basis for their chemistry. "Silica" refers to SiO2 chemistry. The fundamental molecular unit of silica is one small silicon atom surrounded by four large oxygen atoms in the shape of a triangular pyramid - this is the silica tetrahedron - SiO4. Each oxygen atom is shared by two silicon atoms, so only half of the four oxygens "belong" to each silicon. The resulting formula for silica is thus SiO2, not SiO4.
The simplest & most abundant silicate mineral in the Earth's crust is quartz (SiO2). All other silicates have silica + impurities. Many silicates have a significant percentage of aluminum (the aluminosilicates).
Quartz (silicon dioxide/silica - SiO2) is the most common mineral in the Earth's crust. It is composed of the two most abundant elements in the crust - oxygen and silicon. It has a glassy, nonmetallic luster, is commonly clearish to whitish to grayish in color, has a white streak, is quite hard (H≡7), forms hexagonal crystals, has no cleavage, and has conchoidal fracture. Quartz can be any color: clear, white, gray, black, brown, pink, red, purple, blue, green, orange, etc.
Purple quartz is called amethyst. The coloring agent for amethyst is not agreed upon. Some workers say that it is due to Fe+4 impurity, some say the impurity is Fe+3, and others say it is Mn.

This Brazilian quartz crystal has a rather unusual form. Due to a growth interruption, a single prism split into three partly-intergrown prisms. Unfortunately, the longest one has noticeable termination damage.

Those sort of not-quite-windows that cover basements. There used to be more of them around, I'm sure.
Very large calcite plates have left impressions in the quartz. Some of the calcite is still there in thin layers. Maratoto Valley.
Mid-Century remodel on Mt.Tabor in Portland with Quartz Carpet throughout the main living area, hallways + kitchen. Pictures courtesy of Kammen Architecture, California.
Quartz Carpet is a slip-resistant natural stone floor that combines a unique, foot-massaging finish with natural quartz granules in a clear low resin finish for an uncluttered, sophisticated look that can be found in some of the most luxurious residences and bespoken commercial projects throughout the world.
Seamless when finished, a Quartz Carpet floor in installed on site and can accommodate any contour in the surfaces, leaving you with a clean, modern look that adds gracious beauty to your home.
Made out of millions of stones, polished by nature our floors are compatible with radiant heat and are ideal for every room in your home. With the same maintenance as a regular carpet, quartz carpet is the result of over 30 years of product development in Europe, having developed a unique coating system for quartz granules that ensure uniform color, UV stability and a color range with over 1,000 color options.
Benefits:
Anti-slip texture
Infinite color range and combinations
Stain resistant
25 + year projected life cycle
Easy to Maintain
Naturally beautiful
Totally seamless

Quartz is an abundant mineral in the Earth's continental crust. It is made up of a continuous framework of SiO4 silicon–oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall formula SiO2. There are many different varieties of quartz, several of which are semi-precious gemstones. Throughout the world, varieties of quartz have been, since antiquity, the most commonly used minerals in the making of jewelry and hardstone carvings.

A set of crystals discovered in one of Switzerland's many caves. A team of guys has been excavating these for a few years and now has them on tour with a short film. They are the largest quartz crystals in....something. they are big. This one is smokey quartz.
