Akibatnya (Result) rekristalisasi garam yang kemudian mengakibatkan permukaan glasir mengelupas, retakretak, bahkan mungkin benda menjadi pecah. recrystallization of soluble salts resulted surface flaking and spalling can occur, causing sections of a ceramic/ stone to break off.
Kondisi yang direkomendasi (Recommended Condition) 45 - 55% RH, 10 - 30 C
Catatan: Beberapa lempung masakini yang banyak digunakan untuk membuat keramik dan berbagai pernikpernik untuk hiasan tekstil mengandung garam-garaman yang mudah menyerap air. Jika benda ini dimasukkan dalam ruang dingin secara mendadak, maka akan muncul deposit garam yang menempel pada permukaannya. Jika garam-garam yang mengkristal terdapat pada bagian dalam benda, maka akibatnya benda tersebut akan retak-retak, bahkan mungkin pecah. Notes: Some modern clays have a high salt content, and there have been instances where recently purchased objects have fallen to pieces with the absorption in the summer and subsequent drying in the winter. Ceramics with signs of salt deposit on the surface should should be maintained in a stable environment, and fluctuation relative humidity can lead to breakdown of the objects.

Secang-wood and mengkudu were (21) in common use by using mineral alum (Javanese called it as tawas) and plant alum (probably Jirek). However, the plant alum was considered the older mordant than the mineral alum. [The raw materials were treated with oil (castor) and lye (ash from burning rice stalks, or trunks of various trees of banana) that dyes from Morinda mixed with Jirek, Symplocos fasciculata Zoll.] Sugar, indigo, and coffee from Java and Sumatera were exported to Europe.

The textile with geometrized (1) Ikat stylization of human, bird, reptilian, and floral forms. Those like textile producing regions are Kalimantan (jackets and breechclouts from Dayak Iban, D.Bahau and D.Kenyah), Sumatera (ulos from Batak, Palepai and Tampan from Lampung), Sulawesi (Toraja), Nusatenggara (Timor and Sumbawa) and Bali. Songket or supplementary warp was also present in that time (?). on the bronze-wares from that era is similar to the textile design and pattern (2) Motifs of No.1. Bronze-wares from that era, for example kettle drums and axes which were influenced by the Dongson’s culture (Tongkin, Vietnam).

There are 3 species of Gossypium, i.e. G. herbaceum (the most common), G. obtusifolium (in Southern Sumatera, cultivated by the Dutch), and G. brasiliense (Malay Peninsula, cultivated by the British).
sappan-wood (secang) already was one of the outstanding export stuffs to (6) IntheAceh, Arab. The secang dye work was considered as the oldest native red dye work.

Mangosteen flower motifs in Prambanan temple reliefs (also similar to in Palembang) or in Design Javanese Batik, jelamprang, attesting to origin in the Hindu-Indonesian Period. There was a barter trade which were Indonesian cotton cloth and Chinese silk. Silk patola cloth (may from India) also present in the era (Javanese and Sumatrans called as ‘cindai’). The Sung dynasty mentions that cotton goods from Java were used as princely presents.
(9) pakan (weft) together with import silks were brought by Indians and Islamic (10) Ikat traders to Java and Sumatera (possibly, also applications of beads, sequins, glass/
mirrors, and gaining of the knowledge of technique for mixing color/dye). The regions of the two islands that were contacted by the mentioned traders were as indication of silk and songket clothes, and probably silver and gold threads. Other regions: Palembang (South Sumatera), Donggala (Central Sulawesi), Bugis (South Sulawesi) and Bali. In old Javanese written source suggest that ‘kain prada’ enjoyed very great popularity in aristocratic circles in East Javanese Kingdom of Madjapahit. (In Bali, gold leaf was an important article of commerce imported from China and Thailand via the port of Singaraja in the latter half of the 19th century). the fall of Constantinople in 1453, the European merchants (11) Because sought to purchase spices, which at that time were very rare and quite expensive, directly the producing country, i.e. Indonesia. Palembang, was cultivated the mulberry trees for Bombix mori foods (silk (12) In coccon), it was also in Sulawesi. Typical silk cloth colors are red, green, blue and other bright colors. Silver and gold threads was utilized throught the supplementary weft technique, which raises the metallic threads to the surface of the cloth with design of geometric and stylized floral meanders. were mineral alum and madder imported from Mecca and Aden (15) There (Medinah), included coral and copper. Agung introduced the Islamic-Javanese calendar and was patron (19) Sultan of the Arts and Crafts.

Its ultimate aim was the establishment of an Independent Indonesian State.
