Sodalite

Chemical Formula: Na4Al3(SiO4)3Cl

Sodalite is a rare, rich royal blue mineral widely enjoyed as an ornamental stone. Although massive sodalite samples are opaque, crystals are usually transparent to translucent. Sodalite is a member of the sodalite group and together with hauyne, nosean and lazurite is a common constituent of lapis lazuli. Discovered in 1806 in Greenland, sodalite did not become important as an ornamental stone until 1891 when vast deposits of fine material were discovered in Ontario, Canada. It has since been named Princess Blue after Princess Patricia who, upon visiting Ontario some time after its discovery, chose sodalite as interior decoration for Marlborough House in England.

A light, relatively hard yet fragile mineral, sodalite is named after its sodium content; in mineralogy it may be classed as a feldspathoid. Well known for its blue colour, sodalite may also be grey, yellow, green, or pink and is often mottled with white veins or patches. The more uniformly blue material is used in jewellery, where it is fashioned into cabochons and beads. Lesser material is more often seen as facing or inlay in various applications. Although very similar to lazurite and lapis lazuli, sodalite is never quite comparable, being a royal blue rather than ultramarine. Sodalite also rarely contains pyrite, a common inclusion in lapis. It is further distinguished from similar minerals by its white (rather than blue) streak. Sodalite's six directions of poor cleavage may be seen as incipient cracks running through the stone. Hackmanite is an important variety of sodalite exhibiting tenebrescence: when freshly quarried, it is a violet to red colour and gradually fades to a white or green in sunlight. If left in a dark environment for some time, the violet will return. The process is accelerated by the use of shortwave ultraviolet light. Much sodalite will also fluoresce a patchy orange under UV light.

Sodalite is found in only a few places on earth: at Mount Vesuvius near Naples, in Canada, Greenland, Norway, Portugal, Romania, and Russia. The sodalite from Kremer Pigmente comes from Brazil.

Caution:

Materials impregnated with oil may spontaneously combust (auto-oxidation). Burn rags under supervision or dry outspread.

 

Special Sale: "Fine Colored Glass Pigments"

The colored glass is produced by melting lead crystal glass with heavy metal oxides, thus a wide variety of colors is achieved. The light fastness of all colored glass powders is excellent.



The colored glass pigments can be used in all media, such as oil, acrylic dispersions, lime and all kinds of glues. In certain mortars and cements the pigments may cause blooming. For application in exterior environments it is advisable to do trials first. The colored glass is crushed and then ground to a gritty powder of about 0.25 mm. The powder is then sieved.

Etching Varnish RP

silky gloss, deep black etching varnish

The asphalt based etching varnish offers a high durability on the plate while maintaining continuing flexibility. It prevents lines and dots in drawings from chipping or fraying for a longer period of time (up to two months). Additionally the silky gloss and deep black finish reduces surface reflections.

Please follow below link for a video showing the development of the etching varnish RP and an application guide:

Marble Gravel Stone Chips

In general marble is the denomination for metamorphous white or coloured rock with a share of calcite of more than 50%. Only seldom is marble unicoloured. Particals other than marble turn the usually snow white material into striped, flamed spotted, strealzed, tigered coloured marble. Fevric oxyd turus marble into red; ferric sulfid into bluish-black; brown iron, ferric- and mangancarbonat as well as ferric oxyd lead to yellow and brown hue; ferric silicats (esp. Chlorid and epidot) lead to green colours. Grey, bluish and black hues may also stem from graphite or bitumen.
