Can You Name All The Blue Hues, Shades, Tints, Tones And Other Variations?

There are hundreds of blue shades and we have many examples of a certain color name assigned to different HEX codes. On the other hand several blue colors are known under more than one name. We’ll try to present as many blue tints and hues as possible in slightly different arrangement as you might expect. Each color carries its own story and this article is touching dozens of them.

Royal cobalt blue For Trust And Authority

Royal cobalt blue is used to express and emphasize authority for many centuries. It is no coincidence police uniforms are so often blue or mainly of blue color. Its effect on human psychology is in most cases calming and ancient culture associated it heaven and gods. The reason is obvious: while royal cobalt blue is not so widespread in nature as some other colors, it dominates sky and water, two major elements in nature, both closely associated with divinity.

When King of England (George III) needed color with strong impact to immediately express royalty, several clothiers across the country tried to develop the right color and shade. Ultimately Scutts Bridge Mill won the contest. Queen Charlotte wore the robe in this color, what gave the color an alternative name Queen Blue.

With addition of white or black we can instantly create dozens of shades and tints for the same color and with different processes of production and addition of some red or yellow inevitably followed. Especially addition of red led to dramatic changes, what can be seen at royal purple above. It’s actually pretty interesting to find out how many ways are to make color royal cobalt blue, which is szpposed to be a so-called basic or primary color.

Around 1950 another, lighter shade of royal cobalt blue became known as royal and with an introduction of computer graphics (plus numerous limitations, which were gradually changed) and so called web safe colors, we got almost more than we can handle. Simply naming colors with numbers seemed a practical idea, yet it doesn’t guarantee the standardization.

Manufacturing Techniques of Porcelain Enamel

There are two major groups of standard process steps used in manufacturing porcelain enamel materials:

Surface preparation is for removal of soil, oil, corrosion and similar dirt from the basis material. The clean surface allows the porcelain enamel to bond well with the basis material.

Coating, including ball milling and enamel application. Ball milling is performed to mix and grind frit and other raw materials, forming an enamel slip of appropriate consistency for a particular application.

Efcolor cold enamel coating

Efcolor enamel powders are fired at just 150ºC, so there is no need for a specialist kiln. They can be baked in your home oven, or use the specially designed Efcolor Tea Light Stove (If you have a fan assisted oven you might need to check where you place your pieces, so that the fan doesn’t blow the powder off before it has had a chance to set).

Efcolor enamel coating can be used on a wide range of surfaces inlcuding wood, porcelain, glass, silver, copper, bronze, brass, stone, ceramic or any other surface that can be fired at 150ºC… including our great range of copper blanks which can be found here.

You can get some great effects by sifting through stencils or shapes, or by adding elements to the powder and then baking in place. We recommend you get a sifter/sieve top to make it easier to spread the colour over your surface.

Water Use of Porcelain Enamel

The cleaning processes for removing oil and dirt employ water based alkaline cleaners. Acid pickling solutions are used to remove oxides and corrosion and to etch the surface of the workpiece. Water is also used to rinse the basis material after it has been cleaned by the above listed processes.

A water solution of nickel salts is used in nickel flash operations in the steel subcategory.

The ball milling operation uses water for washing out the ball mills between mixing batches and for cooling the ball mills. During application of the porcelain enamel slip, water may be used as a curtain device for entrapping waste slip from overspray.

The characteristics of the wastewater generated by a porcelain enameling facility may vary depending on basis material cleaning and coating.

Cadmium Yellow Medium

Cadmium Yellow Medium is a Series 4 opaque color. It has a
masstone of intense rich yellow, with a very similar undertone. It
has a strong Cadmium pigment which is sensitive to moisture and
should not be used outdoors.

Color Comparisons

Cadmium Yellow Light / Arylamide Yellow Light / Cadmium Yellow
Medium / Arylamide Yellow Deep / Cadmium Yellow Deep

In this sequence of bright yellows shown side by side it is
possible to compare the cadmium colours with similar arylamide
colours. Cadmium Yellow Light is distinctly greener that the other
colours shown here and should be compared to Transparent Yellow
which in masstone looks rather muddy but when White is added has
the same lemony yellow colour as Cadmium Yellow Light.

Arylamide Yellow Light sits between Cadmium Yellow Light and
Cadmium Yellow Medium and is a very bright and opaque colour.
Cadmium Yellow Medium is a mid point yellow colour and Arylamide
Yellow Deep always looks slightly muddy in masstone, but is bright
in tints, but not as bright as Cadmium Yellow Deep which is shown
next.

The long swatch at the bottom shows Arylamide Yellow Deep which is
transparent enough to be used as a glaze. The other yellows shown
here are rather too opaque to be used in glazing.

What is the Porcelain Enamel Industry?

Porcelain enamel is the application of glass-like coatings to metals such as steel, cast iron, aluminum or copper. The purpose of the coating is to improve resistance to chemicals, abrasion and water and to improve thermal stability, electrical resistance and appearance.

The coating applied to the workpiece is a water based slurry called a “slip” and is composed of one of many combinations of frit (glassy like material), clays, coloring oxides, water and special additives such as suspending agents.

These vitreous inorganic coatings are applied to the metal by a variety of methods such as spraying, dipping, and flow coating, and are bonded to the base metal at temperatures in excess of 500 °C (over 1000 °F). At these temperatures, finely ground enamel frit particles fuse and flow together to form the permanently bonded, hard porcelain coating.

At the time of the 1982 rulemaking there were approximately 130 porcelain enamel facilities in the United States.

Enamel Powder Transparent Red

This is a low temperature resin based enamel powder which can be used on metals such as silver or copper, along with glass, wood, porcelain and stone. As with all enamels, this Transparent Red enamel does not require the use of a kiln, as it can be fired in a conventional oven at 150°C.

This fabulous product enables anyone to create enamelled jewellery designs with ease. Simply sieve onto your chosen backing, transfer to a firing plate, and fire in a pre-heated oven at 150°C for 3 – 5 minutes. Care must be taken when removing your piece from the oven as it will be hot. A Sieve Top (861 700) may be useful for easy application of the powder.

Properties of black cobalt coatings

The optical properties of electrolytic black cobalt coatings with different film thicknesses are reviewed.

Although the intrinsic selectivity of black cobalt is only moderate, efficient selective surfaces can be prepared on highly infrared reflecting metals like smooth copper. The optical and structural investigations show that the porous material consists of a granular distribution of a cobalt-rich phase, which causes a significant infrared absorption.

Due to this, the angular dependence of the thermal emission is strongly dependent on film thickness. The influence of different annealing steps on the film properties is discussed.

It is shown that black cobalt can be used in high-temperature designs of flat plate evacuated tubular collectors, provided the annealing process is performed under inert conditions. If the coating is used in air, degradation may occur due to oxidation of cobalt metal above 200°C.
