Tengujo Japanese Paper 6g · 48×94 cm · pack of 40 sheets

Tengujo Japanese Paper 6 g/m² — the lightest in our Japanese paper range

6 g/m² Japanese paper in 100% manila fiber (Manila hemp, abaca fiber, Musa textilis), in a pack of 40 sheets of 480 × 940 mm. Declared data: pH 6.7 and machine-made production. The whole sheet measures 0.4512 m² and weighs 2.71 g: it is the lightest in our Japanese paper range. The name tengujo is historically associated with kozo; this sheet is not kozo.

What is it used for?

What follows describes where this weight fits; the decision about the artwork is yours.

• Document lamination — applying Japanese paper to the entire surface of a sheet.
• Graphic works on paper — when adding the least possible mass over the image matters.

Why choose the Tengujo 6 g?

• Machine-made — in the 2021 ICOM-CC (International Council of Museums Committee for Conservation) study, the authors looked for hand-made Japanese paper of 6 g/m² for their comparison and found none commercially available below 10 g/m².
• Mass, which is data, not an adjective — 0.4512 m² of sheet and 2.71 g of paper. It is the lightest weight in our range that adds to the object.
• Declared fiber and pH — 100% manila and pH 6.7. The alkaline reserve is not declared, in either direction: they are two different measurements.
• 480 × 940 mm sheet — covers larger-than-folio formats in one piece, without joints.

Which of these tengujo: the criterion is mass

We sell several Japanese papers of the same fiber that do similar things. The selection criterion is how much mass can be added to the object, not price or ease of handling.

• Tengujo 6 g — the one that adds least: 2.71 g in the whole sheet. When the surface to be treated is large and the goal is to add as little as possible.
• Tengujo Kashmir 9 g — same sheet format and same fiber, with 50% more mass (4.06 g); sold in a pack of 40 sheets. A bit more body for handling the sheet. It is the weight documented in the facing of the paint layer (facing) of the Allegoria con il trionfo di Firenze by Alessandro Allori, an oil painting on canvas from 1589 (Getty, Conserving Canvas).
• Bib Tengujo — smaller sheet and the densest of those compared here.

Presentation and storage

• Presentation: pack of 40 sheets of 480 × 940 mm (0.4512 m² and 2.71 g of paper per sheet).
• Storage and shelf-life conditions: no published data for this item.
• This paper carries no pictogram or hazard statements: a sheet of paper is an article, not a substance or a mixture, and is not subject to CLP classification (Regulation (EC) 1272/2008 on classification, labelling and packaging).

Where the data ends: the limits of this paper

• Direct contact with photographic material: not endorsed. No PAT test (Photographic Activity Test, ISO 18916 standard — ISO, International Organization for Standardization) is on record, which is the test required to declare a material suitable for direct contact with photographs.
• Alkaline reserve: not declared, in either direction. It is a different measurement from pH.
• Tensile and tear strength: no published data. What is data is the mass: 2.71 g of paper in the whole sheet. It is the weight in our range that adds the least to the object.
• Fiber direction: not declared. It should be checked on the sheet itself before cutting.
• Permanence and ageing: no published data for this paper.
• Uses: none declared, and no adhesive recommended. The decision about the artwork is the conservator's.
