Authenticity is a key concern when collecting antiquities. While banning the trade would not solve the appearance of fakes or looted items, collectors should be aware that there are alternatives and practices that prioritize the preservation of our cultural heritage while satisfying individuals’ interest in ancient artifacts.

Antiquities are precious tangible links to our collective past and have a powerful appeal that transcends mere aesthetics and craftsmanship. However, they can be fragile and require special care. Ideally, an antiquity should be kept in a secure environment that is out of direct sunlight and away from chemical exposure. It is also recommended that any significant change in temperature or humidity should be avoided.

The global antiquities market is regulated by strict international conventions, national laws and ethical guidelines. These regulations prevent the sale of illegitimately excavated or illegally obtained archaeological materials from disappearing into private collections without proper documentation. The 1970 UNESCO Convention provides the fundamental framework, requiring that all transactions involve documentation of legal export from the country of origin. However, the definition of national patrimony varies widely across countries and some claim ownership of all archaeological materials found within their borders regardless of historical collection patterns or good faith acquisition.

Distinguished provenance, museum exhibition and scholarly recognition significantly enhance antiquities values by providing authentication support and market credibility that appeal to sophisticated collectors. The specialized nature of the antiquities market presents distinct valuation and legal complexity requiring expert analysis.

Specialized fine arts insurance and certified appraisals provide protection and value that are customized for antiquities’ unique characteristics. Authentication experts, conservators and academic advisors provide expert guidance on legal compliance, import/export restrictions, ownership rights and due diligence requirements that ensure safe and compliant collecting.

The global antiquities market is a complex ecosystem that intersects with centuries of culture, international law and ethical concerns. As such, there is a vast array of potential legal issues, ethical considerations and responsibilities to consider when acquiring or selling antiquities. It is vital to seek out a trusted advisor who can help navigate the various complexities of the market.

Due Diligence

Due diligence is a critical business process that ensures financial stability and legal compliance. It’s used in many different industries, including real estate and M&A (mergers and acquisitions), and it helps businesses validate information before making high-stakes decisions.

When it comes to antiquities, due diligence involves research into the object’s provenance. Provenance research reveals who owned the artifact at key points in its history, and it also helps prevent illicit trafficking of cultural property. Unfortunately, few antique buyers conduct thorough provenance research before purchasing items in the four-figure range and above. This is a serious risk to the broader field of collecting and could be exploited by criminals to smuggle antiquities into countries where they are illegally exported.

To perform proper due diligence, a collector should ask for copies of all documentation related to the object’s history. This should include bills of lading, invoices, customs entry forms, export permits, and other paperwork that tracks the object’s movements over time. It is also important to look into whether an object has been reported as stolen in the Art Loss Register and INTERPOL databases.

Due diligence in the art world is similar to that used in the real estate industry, and it’s essential to the safety of all parties involved. It allows potential buyers to investigate a home or other property before officially signing a contract, which can save them from ending up with a home they aren’t happy with for any number of reasons, including structural issues, flooding hazards, or noisy neighbors.

When storing antiquities, it’s important to make sure they are protected from moisture and sunlight. Also, storing them in acid-free boxes or paper enclosures is best for preserving the items. These containers help keep out oxygen, which can discolor or weaken certain ceramics over time.

In addition to performing due diligence, it’s important for museums to advocate for stricter laws and regulations around the buying and selling of antiquities. Museums can use their power and influence to push for laws that define “antiquities” as narrowly as possible, establish high thresholds for reporting requirements, and limit the impact of law enforcement’s new antiquities regulations on legitimate sales.

Provenance Research

The discipline of provenance research is a key element in the overall curatorial work of a museum. It is the detailed, interdisciplinary research that traces the ownership history of an object or artifact from its place of origin to its present location, and sometimes back again. In addition to revealing information about the authenticity and attribution of a work, it can also illuminate larger historical narratives concerning the art market and the interplay between individuals, institutions, and nations.

Provenance research is most often conducted using archival records—such as sales or purchase receipts, shipping documents, or inventory lists—but the objects themselves can also carry important clues, such as labels or stamps applied by previous owners to the reverse of a painting, the plinth of a sculpture, or the inside of a book cover. A thorough examination of the scholarly literature and specialized databases is also part of the process, as is careful review of auction catalogs. The Ryerson and Burnham Libraries at the Nelson-Atkins offer a variety of tools to support provenance research.

In recent years, provenance research has come to the forefront as museums have faced challenges over the return of antiquities that were illegally looted from their holdings in countries such as Syria and Greece. Additionally, the Washington Principles on Nazi-Confiscated Art and the Native American Graves Protection and Repatriation Act have added an ethical dimension to the field of provenance research.

Regardless of these issues, the broader context for provenance research is one of establishing lawfully held, scholarlyally valuable objects in a museum collection. This is particularly important for archaeological material and ancient art, where a full, contemporary ownership history may not be obtainable.

In keeping with museum ethics and AAM’s Nazi-Era Provenance Guidelines, the Museum is making a concerted effort to research the past ownership of paintings, decorative arts, sculptures, and works on paper in its collections that possibly passed through continental Europe between 1933 and 1945. The results of this research are publicly available on the museum’s Nazi-Era Provenance Internet Portal. Moreover, as an AAM member, the Museum will continue to prioritize researching Nazi-era provenance for European paintings, sculptures, and drawings it acquires or proposes to acquire.

Conservation and Restoration

The distinction between conservation, preservation and restoration is an important one when it comes to preserving the integrity of historical artifacts. Conservation is any action that maintains an object in its current state, minimizes change and slows or prevents further deterioration. The goal is to prolong the life of an object while ensuring that it remains accessible for present and future generations. Preventative conservation can be done through storage, stabilizing materials and chemical treatments that are typically reversible.

In contrast, restoration is a more invasive process that attempts to return an object to its original or assumed condition. This can be done through structural alterations, replacement or repair of materials, and painting using reversible paint products. In some cases, this can cause objects to lose their historic integrity.

When it comes to artifacts, it can be challenging to determine whether a particular piece should be conserved or restored. Cultural heritage sites in particular are constantly changing as the societies that inherit them transform and shift identities. The Parthenon has been a temple to both pagan and Christian gods, and the Hagia Sophia has served as both a cathedral and mosque over time. Choosing to preserve or restore an artifact to a specific historical period often carries significant political and cultural implications.

For example, if an iron car was left out in the weather for years, it might begin to show signs of corrosion or rust. A conservator could choose to apply a chemical treatment to stop the oxidation or even replace the entire piece of metal if it were damaged. This would be considered restoration and, if not carefully thought out, could erase the historic marker that this car once was a functional tool for a specific purpose.

The museum’s Curatorial team recently began compiling a list of artifacts in need of conservation. This included a model of the USS Arizona that was built aboard the ship before World War II. This model was showing signs of dry rot, so the team reached out to Tamar Maor at TM Art Conservation in Houston for help. After a thorough examination of the model, Maor recommended a combination of reversible and non-invasive conservation treatments that were successful in preserving its integrity.

The Basics of Plumbing

Castle Rock Plumbing is the hidden hero that keeps fresh water flowing into our homes and wastewater draining away. Without it, life would be much more difficult.

Plumbing

Plumbers install and repair the piping that delivers water and removes waste from homes and businesses. They follow strict regulations and inspections to ensure safety and functionality.

Plumbing codes and standards provide critical guidelines for safe and efficient water systems in buildings. They establish minimum requirements for materials, installation methods, drain sizes, and more. They also dictate how the system should withstand environmental challenges. These codes and standards vary from region to region, and it’s important for contractors to understand how they affect their work. For instance, local code amendments might require different pipe materials or installation techniques than those in national standards. Failing to adhere to these guidelines could result in costly rework or even dangerous situations.

Understanding these codes and standards is an essential part of a plumber’s job, as it ensures that all parties involved in a project are working with the same information. This includes engineers and designers, construction crews, and inspection staff. In addition, it helps ensure that the building meets minimum requirements for health and safety. In the past, failure to adhere to these standards has led to a number of catastrophic consequences, including fires and explosions.

In addition to ensuring the safety of plumbing installations, codes and standards are also crucial for promoting water and energy efficiency. They help reduce demand on a valuable natural resource while simultaneously reducing utility costs for homeowners and businesses.

While plumbing codes and standards vary by region, they all share a common goal: to protect public health and safety. Codes are based on best practices and the most up-to-date research. They are updated regularly to reflect new technology and developments in the field.

A national plumbing code was first developed in 1955 by a committee of experts from the American National Standards Institute (ANSI) and the American Society of Mechanical Engineers (ASME). The result was a document known as ANSI A-40.8-1955, which was used for many government projects.

Today, there are a number of sources for national plumbing codes and standards. These include government websites, professional associations, and industry publications. These sources can provide the latest updates and amendments to existing regulations, and they can also explain how these changes impact the everyday work of a plumber.

Federal and state regulations

Plumbing regulations set the standards for safe, functional, and environmentally responsible plumbing systems. They include rules regarding materials, installation procedures, and inspections. Adherence to these codes is critical for plumbers, as failure to do so can result in dangerous conditions. It is also important for plumbers to keep up with changes to these codes, as they are regularly revised to reflect new technologies and safety concerns.

A plumbing system consists of the pipes and fixtures that deliver water and remove wastewater in homes and businesses. It includes a network of water supply lines, storage tanks, and fixtures; drain pipes, traps, and vents; and soil, waste, and vent pipes that connect to a municipal sewer or a private septic system. It also includes a system of faucets, sinks, bathtubs, showers, toilets, and appliances.

The laws regulating plumbing vary from state to state. However, most states have similar requirements. For example, the State of Oklahoma requires all plumbing work to be performed by a licensed professional and to adhere to the International Plumbing Code (IPC). The IPC is a set of comprehensive regulations that governs all aspects of plumbing practice.

Local regulations add to national standards by establishing safety, health, and environmental requirements specific to an area’s needs. These requirements may address issues like seismic safety in earthquake-prone areas, water conservation in drought-prone regions, or the use of nontoxic chemicals in drainage systems. They may also mandate plumbing systems to use lead-free fixtures and components.

In addition to local requirements, federal regulations cover the design and construction of plumbing systems. These regulations ensure that plumbing systems are safe and efficient, preventing water contamination, pipe failures, and other hazards. They also help ensure that plumbers are trained and qualified to perform their jobs properly.

A plumbing inspector is an individual who inspects and tests the plumbing systems of buildings to ensure compliance with the national and local codes. They are required to have a license from the state and undergo regular training to keep up with changing standards. In addition, they must have experience in the field to be qualified to conduct an inspection and test. If they find any violations, they must correct them before the building is occupied or rented.

Plumbers

Plumbers are essential to ensuring safe and efficient water and waste systems. They install, repair and maintain pipes and fixtures, such as sinks, toilets, faucets, showers and water heaters. They also inspect and test plumbing systems to ensure compliance with codes and standards. Plumbers often work in a variety of settings, including residential and commercial.

Some of the most common tasks that plumbers perform are fixing leaky faucets, toilets and shower heads, clogged drains, and water heater issues. They use specialized tools and equipment to diagnose problems and make repairs. They may also be responsible for installing or repairing gas lines. In addition, plumbers may be called to handle more complex projects such as rerouting or modifying existing piping to accommodate new appliances or fixtures.

Regardless of the type of plumbing project, all plumbers must be familiar with industry standards and codes to ensure safety and proper installation. They must also have strong problem-solving skills to identify and resolve issues quickly. Moreover, they must be comfortable working with hand tools and in confined spaces. Plumbers who specialize in commercial or industrial construction may be required to have additional training and certification.

A career as a plumber can be lucrative and rewarding for those who enjoy hands-on work and solving problems. Plumbers typically do not need a bachelor’s degree to start their careers, and can enter the field through trade schools, apprenticeships or on-the-job training programs. They must also obtain a license to practice in their area. In addition, plumbers must attend continuing education classes to stay abreast of advances in technology, new regulations and techniques. Continuing education requirements can help plumbers stay competitive and provide high-quality services to their clients. They can also improve their job prospects by earning certifications from reputable organizations. These credentials can demonstrate their knowledge and expertise in the field and improve their chances of landing higher-paying jobs. In addition, these certifications can help plumbers earn professional development credits that can be applied toward their license renewal. Moreover, these credits can be used to continue their education and pursue advanced training opportunities.

Basic concepts of plumbing

Plumbing is the set of pipes and fixtures that bring freshwater into a home or building and remove wastewater. It is a complex system that requires knowledge of local and national standards, as well as professional expertise to ensure safe and effective operation. This article outlines the basics of plumbing, including how it works and how to repair common problems. It also discusses the role of plumbers and the importance of following plumbing codes and regulations.

Plumbing systems consist of two main pipe systems: the sewer pipes that evacuate waste and the supply water pipes that deliver freshwater. The latter connect to fixtures like sinks, showers, and toilets, as well as appliances like dishwashers and washing machines. These systems must be properly installed and maintained to prevent leaks and other issues. The Environmental Protection Agency sets guidelines for drinking water quality and promotes conservation through initiatives like the WaterSense program.

The basic principles of plumbing are simple, but the complexities of installing and maintaining a complete system make it difficult for homeowners to understand. The key concepts include water supply, drainage, and venting. Water supply systems provide clean, safe water for drinking and cooking. They contain the pipes that carry water from the main supply to individual fixtures, as well as the valves and fittings that control the flow of water.

Drainage systems collect and transport wastewater to the sewer or septic system. They also include traps and vents to maintain proper pressure and prevent backflow. Plumbing codes specify materials and design requirements for these systems to prevent clogs and other problems.

Venting systems allow gases to escape from water heaters and other appliances. These systems are critical for ensuring the safety of occupants and preventing carbon monoxide poisoning. They also regulate water pressure and temperature, which is important for ensuring that fixtures work correctly and to minimize damage from high pressures.

The final principle involves using water wisely. This includes reducing water consumption, minimizing waste, and maximizing efficiency. This can be accomplished by using low-flow fixtures, reducing the amount of water used for washing and cleaning, and installing a water meter to track usage. It is also important to use a water softener to reduce the amount of minerals in the water that can damage pipes and fixtures.
