Buddha
Gautama Buddha, popularly known as the Buddha, He is regarded as the founder of the world religion of Buddhism, and revered by most Buddhist schools as a savior, the Enlightened One who rediscovered an ancient path to release clinging and craving and escape the cycle of birth and rebirth. He taught for around 45 years and built a large following, both monastic and lay. His teaching is based on his insight into the arising of duḥkha and the ending of duhkha the state called Nirvana

The Buddha was born into an aristocratic family in the Shakya clan but eventually renounced lay life. According to Buddhist tradition, after several years of mendicancy, meditation, and asceticism, he awakened to understand the mechanism which keeps people trapped in the cycle of rebirth. The Buddha then traveled throughout the Ganges plain teaching and building a religious community. The Buddha taught a middle way between sensual indulgence and the severe asceticism found in the Indian śramaṇa movement. He taught a training of the mind that included ethical training, self-restraint, and meditative practices such as jhana and mindfulness. The Buddha also critiqued the practices of Brahmin priests, such as animal sacrifice and the caste system.
A couple of centuries after his death he came to be known by the title Buddha, which means "Awakened One" or "Enlightened One". Gautama's teachings were compiled by the Buddhist community in the Vinaya, his codes for monastic practice, and the Suttas, texts based on his discourses. These were passed down in Middle-Indo Aryan dialects through an oral tradition. Later generations composed additional texts, such as systematic treatises known as Abhidharma, biographies of the Buddha, collections of stories about the Buddha's past lives known as Jataka tales, and additional discourses, i.e. the Mahayana sutras.
Process: Sand Casting
This Buddha has been created using the sand casting system, also known as sand molding casting. This widely employed manufacturing process utilizes a sand mold to produce metal products and components in various sizes and shapes. Sand casting holds significant popularity in the industry, accounting for approximately 60% of all metal castings. The sand casting process involves six primary steps. First, a pattern or replica of the desired sculpture, in this case, Buddha, is created using a material like wood or metal. The pattern is then placed in a flask, which is a box-like structure divided into two halves. The next step involves packing the flask tightly with specially formulated molding sand, creating a mold cavity that matches the shape of the pattern. The pattern is subsequently removed, leaving behind a negative impression of the sculpture within the sand mold.
The third step is known as gating and risering, where additional channels and reservoirs are added to the mold to facilitate the flow of molten metal and compensate for any shrinkage during solidification. Once the gating system is prepared, the mold is carefully closed and secured. The fourth step involves pouring the molten metal, such as bronze or iron, into the mold through the gating system. After the metal has cooled and solidified, the mold is broken open, revealing the solid metal sculpture. The final steps involve removing any excess material, surface finishing, and polishing to achieve the desired appearance.
Sand casting offers several advantages, including its versatility in producing complex shapes, cost-effectiveness for both small and large-scale productions, and the ability to use a wide range of metals. However, it does require skilled craftsmanship and careful attention to ensure the quality and accuracy of the final sculpture. By utilizing the sand casting system, the Buddha embodies the craftsmanship and artistry of the process, resulting in a captivating and unique metal artwork.
The process cycle for sand casting consists of six main stages, which are explained below
Mold-making -The first step in the sand casting process is to create the mold for the casting. In an expendable mold process, this step must be performed for each casting. A sand mold is formed by packing sand into each half of the mold. The sand is packed around the pattern, which is a replica of the external shape of the casting. When the pattern is removed, the cavity that will form the casting remains. Any internal features of the casting that cannot be formed by the pattern are formed by separate cores which are made of sand prior to the formation of the mold. Further details on mold-making will be described in the next section. The mold-making time includes positioning the pattern, packing the sand, and removing the pattern. The mold-making time is affected by the size of the part, the number of cores, and the type of sand mold. If the mold type requires heating or baking time, the mold-making time is substantially increased. Also, lubrication is often applied to the surfaces of the mold cavity in order to facilitate removal of the casting. The use of a lubricant also improves the flow the metal and can improve the surface finish of the casting. The lubricant that is used is chosen based upon the sand and molten metal temperature.
Clamping - Once the mold has been made, it must be prepared for the molten metal to be poured. The surface of the mold cavity is first lubricated to facilitate the removal of the casting. Then, the cores are positioned and the mold halves are closed and securely clamped together. It is essential that the mold halves remain securely closed to prevent the loss of any material.
Pouring - The molten metal is maintained at a set temperature in a furnace. After the mold has been clamped, the molten metal can be ladled from its holding container in the furnace and poured into the mold. The pouring can be performed manually or by an automated machine. Enough molten metal must be poured to fill the entire cavity and all channels in the mold. The filling time is very short in order to prevent early solidification of any one part of the metal.
Cooling - The molten metal that is poured into the mold will begin to cool and solidify once it enters the cavity. When the entire cavity is filled and the molten metal solidifies, the final shape of the casting is formed. The mold can not be opened until the cooling time has elapsed. The desired cooling time can be estimated based upon the wall thickness of the casting and the temperature of the metal. Most of the possible defects that can occur are a result of the solidification process. If some of the molten metal cools too quickly, the part may exhibit shrinkage, cracks, or incomplete sections. Preventative measures can be taken in designing both the part and the mold and will be explored in later sections.
Removal - After the predetermined solidification time has passed, the sand mold can simply be broken, and the casting removed. This step, sometimes called shakeout, is typically performed by a vibrating machine that shakes the sand and casting out of the flask. Once removed, the casting will likely have some sand and oxide layers adhered to the surface. Shot blasting is sometimes used to remove any remaining sand, especially from internal surfaces, and reduce the surface roughness.
Trimming - During cooling, the material from the channels in the mold solidifies attached to the part. This excess material must be trimmed from the casting either manually via cutting or sawing, or using a trimming press. The time required to trim the excess material can be estimated from the size of the casting's envelope. A larger casting will require a longer trimming time. The scrap material that results from this trimming is either discarded or reused in the sand casting process. However, the scrap material may need to be reconditioned to the proper chemical composition before it can be combined with non-recycled metal and reused.

Finishing: Stone Setting
The Buddha is adorned with an exquisite array of semi-precious stones, including turquoise, coral, and lapis lazuli. These stones are carefully selected and meticulously placed on the Buddha's surface, adding a touch of opulence and enhancing its overall beauty. Each stone is thoughtfully positioned using a high-quality adhesive, ensuring secure and long-lasting attachment. The vibrant colors and unique patterns of the stones create a captivating contrast against the backdrop of the Buddha, elevating its visual appeal and making it truly eye-catching.
Beyond their decorative purpose, these semi-precious stones carry symbolic significance in various cultures and traditions. Turquoise is often associated with protection and healing, coral represents vitality and passion, while lapis lazuli symbolizes wisdom and truth. The inclusion of these stones not only adds to the aesthetic allure of the Buddha but also imbues it with deeper meaning and cultural symbolism.
The intricate placement of these semi-precious stones showcases the meticulous craftsmanship and attention to detail that goes into the creation of the Buddha. It is a testament to the skill and artistic vision of the artisans who delicately adorn the statue, resulting in a truly remarkable and captivating piece of art.
