Lithopone is manufactured by a process (Fig. 1) in which barium sulfide solution is prepared by reducing barite ore (BaSO 4) with carbon and leaching the resulting mass.
While the conclusions of the EU expert panel were considered in this report, Health Canada's Food Directorate conducted its own comprehensive review of the available science. This included evaluating new scientific data that addressed some of the uncertainties identified by the EU expert panel and were not available at the time of their review.
In their role as risk managers, the European Commission and Member States will now reflect on EFSA’s scientific advice and decide upon any appropriate regulatory measures or advice for consumers.

The use of iron in decorative arts dates back to ancient times, but it was during the Middle Ages that wrought iron began to gain popularity for both functional and ornamental purposes. Artisans meticulously crafted rod iron scrolls, which became a hallmark of Gothic architecture. These decorative elements were often employed in cathedrals and castles, symbolizing strength and elegance while providing essential structural support. With the Renaissance era ushering in a renewed interest in artistry and design, rod iron scrolls evolved further, showcasing elaborate patterns and designs that reflected the aesthetic ideals of the time.

2. Metal Iron and aluminum gates are durable and provide excellent security. They can withstand harsh weather conditions and require minimal upkeep. However, they may need periodic painting or sealing to prevent rust.
With pickets spaced about 4 inches apart along the fence panel, welds affix each one to both the top and bottom railings, keeping everything sturdy and completing the unit. A standard panel usually contains about 20 pickets apiece for an overall length of 8 feet. The full height of a finished iron safety fence panel mostly tops out at 5 feet, though 4-foot panels aren’t uncommon either. Local building codes tend to dictate the height required, so your experience may vary. Finally, at either end of a fence panel is a post.
At Orion Ornamental Iron Inc., they specialize in creating custom iron products that add beauty, elegance, and security to any property.

To maintain your aluminum window profile, here are some tips:
Cast iron is known for its strength and resistance to wear and tear, making it an excellent choice for outdoor applications. Unlike wooden fences that can rot, warp, or be eaten by pests, cast iron requires minimal maintenance over the years. It can withstand harsh weather conditions, including rain, snow, and ultraviolet rays, without deteriorating. Even if the paint chips, the underlying metal remains intact, allowing for easy touch-ups that can restore its original beauty. When properly maintained, cast iron picket fences can last for generations, making them a worthy long-term investment.
However, these efforts serve to preserve not just the material but also the artistry and history it represents. Over time, the character it acquires transforms your property into something akin to a local treasure.
This not only enhances the energy efficiency of a building but also contributes to reduced energy bills and a smaller carbon footprint This not only enhances the energy efficiency of a building but also contributes to reduced energy bills and a smaller carbon footprintwindow aluminium profile.It will come as no surprise to learn that modern windows are primarily intended to be ‘warm’. This means that they are not supposed to allow warm air to escape from the house. This parameter is described by the heat transfer coefficient Uw, which gives us the answer to the question of how much heat escapes through the window due to the difference in external and internal temperatures.

While fencing spires act as “posts” in wrought iron fences, posts are the square pieces of fencing that are either bolted to a surface or buried in concrete in the ground. These elements are crucial to the structure and durability of wrought iron fencing. A sturdy, well-installed fence will be able to stand up to season after season of inclement weather. Brackets, on the other hand, are unique to wrought iron fences. These elements hold fencing components to the posts. Brackets typically slide over rails and are set against posts before being screwed into place.
Finials are the decorative tips that are welded on top of your wrought iron fence or gate, and they often add a classic touch to its construction. Commonly known as an urn, these architectural devices were originally designed to bring attention to the apex (or top) of walls, buildings and other structures on castles. Today many finials also grace the tops of clocks, archways, flagpoles and even bedposts!
When comparing the strength of steel and iron, it is important to consider the specific grade and composition of each material. There are many different types of steel and iron alloys, each with their own unique properties and strengths. In general, steel is considered to be stronger than iron due to its higher carbon content and other alloying elements.
The low weight of aluminium windows, compared to other materials, is a significant advantage. This, in turn, enables them to be installed in virtually any location. They are ideal, for example, for use as roof and façade windows and in modern modular construction. The narrow profiles and properties of aluminium contribute to the windows’ low weight.
