The term Si has dual connotation of referring to the Calligraphy pen as well as to the specific bamboo from which pen is crafted. According to Lopen (master) Wangdi Gyeltshen, a renown calligrapher of Central Monastic Body said that, there is also another reed locally called Tshi-nag (a reed with dark colour at its internode) which is available from Wangdi-tse monastery area in Thimphu. Actually, there is no specific origin of the Si as it came to exist simultaneously with the writing culture in Bhutan. Colloquially, all pens used for writing purposes are called as Myu-gu, which the name derived from its raw material Myug-ma (bamboo or reed). That is why any pen used for writing available in the market today, irrespective of what it is made of are commonly called Myu-gu (literally means reed pen). As there are different types of My-gu, thus, apart from the aforementioned Si, the pens are made from a wild fern called Kyer-ma is called Kyer-myug, and the ones made of quill is dro-myug, the nib made from metal is chag-myug. Similarly, sol-myug made from dead amber or charcoal, a talc stone is cut like a pencil for use -do-myug, the chalk comes in packets and used for educational purposes in schools is sa-myug. There are also pir-myug (brush pen) and lastly, the zha-myug, the lead pencil. Regarding the raw material; in Bhutan, Si is traditionally found at Chagdana in Toepai Gewog (Block) in Punakha, and near the Nag-tshang (Manor) at Drametse. It is also found in Kheng region of Zhemgang and at the Yarphel village of Trashi Yangtse district. Si is highly valued as being blessed by superior beings like Lord Manju Shri, Guru Rinpoche, the five classes of dakinis and the Dharma Lord Drukpa Kunleg (4155-1529). Si grows as big as normal bamboo, with short culm or internode, narrow lacuna and thick culm wall. They grow in heights of more than five arm-span. Both the plant and its leaves are generally yellowish. In ancient times, a writing pen was mainly a painting brush in China and in India it was made from the quill (moulted flight feather) of a peacock or other large bird. It is explained that the pen used traditionally in Tibet and Bhutan was made from the plant species called Si, which has thick nodes and grows mainly at lower altitudes. It is obvious that, if writing tradition is gradually disappearing, both the art of making Si as well as its usage is an inevitable element to be gone together. Due to the booming computing technologies and automatic printing machines, the writing along with Si related practices are being gradually driven out of its existence however, realizing its importance and for its revival, His Majesty’s Golden Scriptures Project and other similar projects being initiated by some individual Spiritual masters had help in revitalization of such tradition as well as involving calligrapher to carry on the writing and Si making culture amidst the emerging sophisticated technologies.

National Intangible Cultural Heritage, Republic of Korea Jogakjang refers to the skill of metal engraving or to the artisan who does it. Unearthed artifacts lead us to guess that metal engraving was first attempted during the Bronze Age. Diverse engraving techniques were used during the Three Kingdoms Period (57 BC – 668 AD), and they made noticeable developments during the Goryeo Period (877 – 1394). During the Joseon Period (1392 – 1910), metal handicrafts started to develop as an independent sector. Techniques used in metal engraving include depressed engraving, bratticing, relief engraving, 3D engraving, and inlaying. Materials used are gold, silver, iron, lead, zinc, and tin. Silver is the most commonly used. Favorite designs used are scenery, flowers, birds, clouds, dragons and vines. Esthetic quality or propitiousness became the criteria for selection of the patterns of metal engraving in the later Joseon Period and thereafter.

Gold and silver smithy or metal carving had flourished in the country for a long time as evident from the ornaments worn by women and religious artefacts in monasteries and temples. This art is still being practiced and transmitted. It is a highly specialized art form. A special class of craftsmen called Troe-ko make jewelry of gold and silver and other items such as swords, boxes, teapots, and various ornaments of silver, often thinly plated with gold. Traditional symbols such as the dragon and other beautiful motifs are engraved on the objects. Silverwork is also found on the pillars of temples, altar tables, jewelry and other religious items. Using precious stones and metals such as coral, turquoise, silver and gold, these artisans make brooches, necklaces, bracelets, earrings, rings, amulets with religious content, traditional vessels (Chaka and Trimi) for carrying the much-chewed beetle nut, ritual objects and much more.

Jimzo is a traditional art of forming religious images. Jim means "clay" and Zo means "art", literally "clay art". In Bhutan, it can be traced back to the 7th century, to the time of Tibetan King Songtsen Gampo (569–649?), who is believed to have built 108 Lhakhangs (temples), under which the pioneering Buddhist temples such as Kichu and Jampa Lhakhangs were built. Various clay paintings from different centuries, beginning with the time of Guru Rinpoche, attest to the existence of clay art in Bhutan much earlier. In the time of Terton Pema Lingpa (1450-1521), this art became popular. Towards the end of the 17th century, the art was codified and included by the fourth Desi (temporary ruler) Gyalse Tenzin Rabgye (1638–1696), as one of the thirteen arts and crafts of Bhutan. Later, at the time of Zhabdrung Ngawang Namgyal (1594-1651) in the 17th century, a very skilled sculptor named Trulku Dzing was invited to Bhutan. Trulku Dzing erected numerous clay figures in Punakha and Wangduephodrang Dzong. The art was later codified and included as one of the thirteen traditional arts and crafts of Bhutan by the 4th Druk Desi (temporary ruler) Gyalse Tenzin Rabgye in the late 17th century. Since then the art of sculpting has been maintained and passed from teacher to students over many generations until today. Bhutanese jim zop (sculptors) are known for the quality and intricacy of creating delicate clay sculptures. They practice sculpting as a pious act since it is based on the iconographic principles of Buddhist art. It is very important to adhere to the rules that prescribe the precise measurement of the body structure in relation to the limbs, postures, eyes, ears, fingers and nose and the body tints, garments and ornaments. a. Religious Statues and Ritual Objects: Sculptors make clay statues, ritual objects and tsha tsha (miniature clay stupa) and clay masks worn during festivals. Numbers of exceedingly fine and intricate religious sculptures and ritual objects made of clay can be seen in every temple, monastery, and the dzongs of Bhutan. These clay sculptures vary in sizes, varying from tiny statues to over twenty feet. There are clay sculptures of the Buddhas and Bodhisattvas, various deities, gods, goddesses and prominent religious figures which depict the foundation of faith, worship and reverence for the Buddhists. b. Types of Clay used in Sculpting: Clay is the basic material for making sculptures. A special kind of clay can be found deposited in small quantities between mud and gravels usually in marshy areas. Sculptors use the best quality clay as the images and objects they make must stand against the change of weather for generations. Clay is processed into three different forms; tsa dam, kong dam, and jim dam. Each one is used for a specific purpose. Tsa dam is made by mixing clay powder with daesho (paper made from daphne plants) in the ratio of 7:3. If paper is not available, pulps made from the raw bark of daphne plant are used as substitute. This mixture prevents the mud from disintegrating when dried. Tsa dam is used for moulding the basic structure of the statue. Kong dam is prepared in the same way as tsa dam, but by adding more water to make the clay relatively thinner and softer. Kong dam is applied over the basic structure moulded from tsa dam to give proper shape to the statue. Generally the proprietor adds any or all of the seven precious substances (gold, silver, and turquoise, and coral, pearl, bronze and any other precious stones) to tsa dam and kong dam in order to increase the aura of the statue. Jim dam is applied as the final and finishing touch to the statue. To prepare jin dam; the clay powder is mixed with water and then stirred thoroughly until it turns into a thin paste. It is then filtered with the help of a thin cloth. The thin filtered paste is collected in a utensil and then placed on fire until the water component is evaporated. What is left in the pot is a very fine powder. This powder is then mixed with daphne papier mache to give it the binding strength which prevents the clay from cracking. This mixture is again mixed with water and stirred and applied to give the final touches to the statue. c. Process of Clay Sculpting: Clay sculpting process starts with the measurement of the space available where the statue will be kept later, or the size required by the owner/sponsor. Accordingly, the basic structural frame is made by using copper wires for smaller statues, iron or steel rods for bigger statues as support. Steel rods are wrapped with copper wire to add the value of the object. Gold and silver wires are considered the best to make the basic frame. The frame is added with tsa dam while the internal part is left hollow for zung to be inserted later. When the tsa dam on the structure dries perfectly, kong dam is applied over it to give all the external physical features, forms and the attires. The parts such as hands and head are made separately and attached later to the body for smaller statues, though the head of bigger statues are made directly with the statue. The sculptor must ensure that the parts made separately are proportionate to the whole structure. Any part of the statue that is not proportionate to the whole body is considered an impious act of the sculptor and therefore must be avoided at all cost. Sculpting is a tedious job, requiring the sculptor to apply the wooden chisel again and again to fill any gaps or remove the lumps over and over again. The statues are left for a long time to allow the clay to dry naturally, and to develop minor cracks which are also left unrepaired to allow air to pass for rapid drying. When no more cracks appear, it means the clay has dried up completely. The cracks are then repaired with tsa dam by mixing with glue. Once this is done, the sculptures are ready for final layers of finishing using jin dam. At this stage the sculpture is finally ready for zung (the inner relic). Learners have to undergo rigorous training for several years under a master sculptor known as Jimzo lopoen. As sculpting for religious purpose is considered a spiritual act, sculptors have to choose the most auspicious day and time to start a project. Once completed, an expert (usually a monk) will insert a zung shing or sog shing (a strut inside the statue as its backbone) and zung consisting of written mantras and other precious substances. Then the statue is painted using appropriate colours. Upon completion of all these steps, a drub or rabney ceremony is conducted by an accomplished lama. The painters and sculptors are highly regarded for their profession.
