Sustainable Product Classification

Our understanding of sustainability in production primarily means manufacturing without using fossil raw materials. Fossil raw materials in general are all substances on our earth that have not yet been processed. Fossil raw materials in the narrower sense are substances like natural gas, crude oil and coal. The CO₂ footprint of a historical energy source is lower the less these three raw materials are required for production. Regardless of the type of energy generation and the corresponding transport expenses, a natural product, such as earth colors, are always more neutral than processed products, such as synthetic iron oxide. The use of cultivated, vegetable materials, such as indigo, is more sustainable than the use of the synthetic products (i.e. synthetic indigo).

In general, we can classify the following of our product groups as sustainable:

Natural earths
e.g. ocher, red bole, terra di sienna, umber, green earth

Mineral pigments obtained from stones
e.g. cinnabar, malachite, azurite, lapis lazuli, basalt, iron mica

Colored lacquers, dyes made from vegetable materials that are lacquered into pigments
e.g. madder lacquer, stil de Grain, indigo, purpurissum

Natural dyes and vegetable colors
e.g. sepia, dragon blood, logwood, saffron, henna, apple tree bark

Mineral fillers
e.g. champagne chalk, marble powder, bolus, quartz powder, granite, cristobalite

Natural mortar and building materials
e.g. pit lime and pumice powder

Natural binders
e.g. warm glue, fish glue, mastic, starch, natural resin, balm, wax, oil

Textiles made from natural raw materials
e.g. canvas

Brushes made from natural hair / bristles

 


NEW: Bone Black exclusive

Bone Black (C.I. Pigment Black 9) is also known as Ivory Black. Animal bones are processed in dry distillation without oxygen (charring). The bone char is then ground and sieved.

Large parts of ordinary bones have a spongy structure. When charring, these smooth surfaces result in gray particles due to the increased reflection of the light. The pigment will turn out deep black if the bones are carefully pre-selected.

Worked in oil the bone black exclusive is nearly as deep black as real ivory black. It is suitable for a wide range of applications such as plastics, paints, varnishes, wood glazes, artists' paints, coil coatings, cement, mortar, paper, etc., especially if dull matt surfaces are required. Bone black reveals its full matt depth in oil and synthetic resins. In aqueous the pigment is more difficult to mix and the color loses its depth.

NEW: Graphene

The production of graphene still is very complex. It is a flat carbon - perfectly composed of one single carbon layer. The stability and strength of graphene is extremely high, the tensile strength is about 130 times higher than steel. Graphene can be seen as a rolled out flat carbon nanotube. It is blacker than real ivory black.

In oily or solvent-based systems, graphene is very rich and deep black. Graphene is impermeable to gases, which is why oily spreads with graphene dry very slowly.

Warning: Graphene has an extremely low specific weight: 5 grams of graphene fit into a 500 ml jar, and about one hundred times lighter than water. A slight breeze can swirl the pigment. Graphene can become electrostatically charged. When dry, it spreads almost by itself. Graphene is a test product, the safety data properties have not been tested yet.

Aquazol®

Aquazol® is a water-soluble synthetic resin, like gum arabic or cellulose glue, which can be used for strengthening or as a binder for retouching. It is soluble in water and other polar solvents, e.g. ethanol, methanol or MEK. The adhesive strength increases with the viscosity of the synthetic resin.

Due to its thermoplastic properties, it can be used as a hot-sealing adhesive (approx. 55°C). The melting range is 110-120°C. It is also used as putty, as a substitute for skin glue, or as an additive for poliment gilding.

We offer the following types with differing specific molecular weight:

#63901 Aquazol® 50
#63902 Aquazol® 200, medium viscosity
#63905 Aquazol® 500, high viscosity

Kremer Pigmente Color Charts

Kremer Pigmente color charts are handmade using the screen printing process. Apart from a few special cases, the original pigments are bound in an aqueous binder based on gum arabic (#63300). This hardly changes the color of the pigment. Exceptions are pigments that cannot be processed in this binder, such as dragon blood and copper resinate.

All color charts come in a filable document folder. The color samples are printed on acid-free 180 gram paper, the individual sheets in A4 format can be placed side by side and compared.
All colors are applied in one layer. Part of the paper was previously printed with a gray scale, which is intended to illustrate the opacity of the pigments. The more opaque a pigment is, the less these gray levels are visible.
