Thitsi samples were collected from Kaingtaung, Mabain and Yaksawk Toawnships, Shan State during October and November. The physico-chemical characteristics of raw and purified Thitsi such as colour, odour, ash, viscosity, boiling range, pH and specific gravity were determined. Moreover, chemical constituents such as moisture and volatile matter, thitsiol, nitrogenous matter, gummy matter and fatty or oily matter were also investigated. In order to get kurome lacquer (purified lacquer), Thitsi were purified, firstly prepolymerized with make-shift homogenizer and followed by filtration and their physico-chemical characteristics and chemical constituents were studied again. Various functional groups of thitsiol were characterized by Fourier Transform Infrared Spectroscopy and elemental compositions of Thitsi were analyzed by Energy Dispersive X-ray Fluorescence Spectrometer. Bamboo lacquerwares were prepared by applying raw and purified Thitsi severally and hardened in the underground cellar by polymerization process. Effect of number of coating on the hardening time of Thitsi-coat on bamboo substrates were investigated at the relative humidity (70–87)% and the temperature (27.1–31.8)ºC of underground cellar. Thisi, the very natural eco-friendly sap, could be significantly enhanced its characteristics by purifying it."}]}, "item_1583103108160": {"attribute_name": "Keywords", "attribute_value_mlt": [{"interim": "Thitsi"}, {"interim": "kurome lacquer"}, {"interim": "underground cellar"}, {"interim": "polymerization"}, {"interim": "hardening"}]}, "item_1583103120197": {"attribute_name": "Files", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "date": [{"dateType": "Available", "dateValue": "2020-10-05"}], "displaytype": "preview", "download_preview_message": "", "file_order": 0, "filename": "Investigation on the Characterization of Thitsi for Lacquerware Processing.pdf", "filesize": [{"value": "277 Kb"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_0", "mimetype": "application/pdf", "size": 277000.0, "url": {"url": "https://meral.edu.mm/record/5648/files/Investigation on the Characterization of Thitsi for Lacquerware Processing.pdf"}, "version_id": "4431108e-d8f1-4df0-a224-b826c77dbac2"}]}, "item_1583103131163": {"attribute_name": "Journal articles", "attribute_value_mlt": [{"subitem_issue": "5", "subitem_journal_title": "University of Mandalay, Research Journal", "subitem_pages": "238-247", "subitem_volume": "11"}]}, "item_1583105942107": {"attribute_name": "Authors", "attribute_value_mlt": [{"subitem_authors": [{"subitem_authors_fullname": "Phyo Phyo Thwe"}, {"subitem_authors_fullname": "Thwe Linn Ko"}, {"subitem_authors_fullname": "Pansy Kyaw Hla"}]}]}, "item_1583108359239": {"attribute_name": "Upload type", "attribute_value_mlt": [{"interim": "Publication"}]}, "item_1583108428133": {"attribute_name": "Publication type", "attribute_value_mlt": [{"interim": "Journal article"}]}, "item_1583159729339": {"attribute_name": "Publication date", "attribute_value": "2020-05-30"}, "item_title": "Investigation on the Characterization of Thitsi for Lacquerware Processing", "item_type_id": "21", "owner": "23", "path": ["1582963739756", "1582967133536"], "permalink_uri": "http://hdl.handle.net/20.500.12678/0000005648", "pubdate": {"attribute_name": "Deposited date", "attribute_value": "2020-10-05"}, "publish_date": "2020-10-05", "publish_status": "0", "recid": "5648", "relation": {}, "relation_version_is_last": true, "title": ["Investigation on the Characterization of Thitsi for Lacquerware Processing"], "weko_shared_id": -1}
