How to create plique a jour with Tom Herman and Patsy Croft.
Plique a Jour is a vitreous enameling technique where the enamel is applied in cells, similar to cloisonné, but with no backing in the final product, so light can shine through the transparent or translucent enamel. It is in effect a miniature version of stained-glass and is considered very challenging technically.
Plique a jour can be created in two ways, one, by saw piercing a sheet of metal or two, by fabricating a structure of wires.This first images shows the tiny wings above the ruby drops as plique a jour formed in wire and enamels laid in.

This second image the plique a jour is created from a sheet of gold that is saw pierced.
With a vision we started.

Test Plates of Enamels
The first video shows Tom saw piercing the poppy petals to create plique a jour.
This second video I am floating the enamels into the poppy stem leaves.
This should give you a good idea of how to create plique a jour, enjoy!

This is what I call Enamel Test Plates! Raj Lathigara, Ph.D. is serious about his journey in enameling. Getting to know your product is so important. I completely understand we are so excited when we see this beautiful art for of enameling, we just want to jump in and start playing.
But, if you can take the time, as Raj did here to make test plates of all your enamels you will find it to be a huge advantage as you begin your journey.

Properties of Opalescent Enamels. Okay, get ready for this. Most modern day opalescent enamels are not truly opalescent but rather semi transparent. A true opalescent is a mixture of two immiscible enamels. (Immiscible Definition
Immiscibility is the property where two substances are not capable of combining to form a homogeneous mixture. The components are said to be “immiscible.” In contrast, fluids that do mix together are called “miscible.”
Components of an immiscible mixture will separate from each other. The less dense fluid will rise to the top; the more dense component will sink. This can also be true of solids but in the case of enamels, it is referring to the molten state.)
The old leaded Thompson were true opalescent enamels. In the case of their 835 Opal White, the glass was immiscible unless fired too hot. If you fire them too hot they become miscible and the resulting glass becomes an opaque. According to the late (great) Woody Carpenter, these enamels also contained arsenic. The “too hot” varied from one batch to another. I have a rather large container of 835 that goes opaque at about 1325 degrees and so as long as you fire under that temperature, your results will be a glorious true opalescent enamel. It should be noted that most medium fusing enamels are meant to be fired hotter than this. It is possible to get them to a glossy stage at 1325 but it will take 3 minutes or more for a small jewelry piece. In actuality, it doesn’t matter how many times you fire a piece as long as it never gets hot enough to change the chemical makeup and cause it to go opaque. Because they are so delicately fussy about temperature, you may find that firing on a layer near the end is safer for you but it really is about the temperature.
The Japanese opals are all semi transparent and not sensitive to overheating. The colors are quite lovely and troublefree but not actually opalescent enamels. Have a look at a Faberge Egg in person some time for an example of Opalescent Enamel. They are delicious.

Yet Another Dead Whale Is Grave Reminder Of Our Massive Plastic Problem
Trevor Nace , CONTRIBUTOR Opinions expressed by Forbes Contributors are their own.
WE have a massive plastic problem.We have to get rid of plastic. Look at this……. A sperm whale was found washed ashore dead after swallowing 64 pounds of plastic debris. The male sperm whale was found on the Murcian coast in southern Spain in late February, reminding us how critical plastic waste in the oceans has become.
Experts found the inner walls of the whale’s abdomen to be inflamed due to a bacterial or fungal infection. This is likely a result of the whale unable to expel the plastics from its system, resulting in peritonitis.
WE have to gert rid of Plastic!
The male sperm whale, an endangered species protected in the US under the Endangered Species Conservation Act, weighed over 6 tonnes and measured 33 feet long. Sperm whales typically eat squid and live around the same lifespan as humans, averaging 70 years.
As a result of the whale’s death, the Murcia government launched a campaign against dumping plastic waste into the coastal town’s water. The coastal community is working to raise awareness of the ever-growing plastic problem in oceans and the need for beach cleaning.
With an increasing amount of plastic discarded in oceans, whale deaths due to ingestion of plastics are becoming far too common. Just two years ago a pod of 13 sperm whales all washed ashore dead from ingestion of plastic waste.
To cope with this dilemma, many countries around the world are phasing out single-use plastic bags as typically seen in grocery stores. Below is a map of where countries are in their phasing out of low-density polyethylene plastic bags.
Green indicates plastic bags are banned
Yellow indicates a tax on some plastic bags
Orange indicates a voluntary tax agreement
Purple indicates a partial tax or ban at a regional level
The European Union is pushing a transition to have all plastic recyclable or reusable by 2030 with many agencies around the world discussing phasing out non-biodegradable plastics completely.
However, in the meantime efforts to clean up beachesand oceans are underway due to dedicated and novel initiatives.
