4. Things to remember • Objects are unique and maybe made of • just one medium/material/component • more than one material/medium/component • Select more durable material/part for labelling • If all materials fragile use alternative method e.g. tie on label

5. Things to remember • Inform all staff about common label location • Remember mistakes cannot be reversed without damage to object • Practice method on non collection object first

6. Selection of materials • For objects made from a single medium use methods below • For object made of mixed media select method to suit the most durable component • To minimise handling and easy access create a set criteria for location • e.g. 1.On the reverse at bottom right hand corner • 2.for textiles on the seam hem next to left side seam Note: take selection of materials and location very seriously as these become permanent

7. Your tool kit- materials for labelling • Artline drawing system pen (black) • Woven cotton tag or ribbon • Artline paint marker (white) • Tyvek numbered label • Pentel hybrid gel (white) • Petroleum spirits • Acetone • Graphite pencils HB (firm) and 2B (softer) • Schwan Stabilo wax pencil • Mylar sheet

8. Your tool kit- materials for labelling • Paraloid B-67(15% in petroleum spirits) • Japanese tissue. Use well matted and smooth tissue, approx. 22 gsm • Paraloid B-72 (20% in acetone) • Distilled water • Paraloid B-72 in (20% in ethanol - optional • Plextol B500 20%  in distilled water • Note: Product formulation and content may vary from stock to stock which could may alter the performance of the product.

Allow to dry. • Remove from mylar sheet • Apply 20% plextol B500 in distilled water to label underside and place in position on object • Press firmly and evenly to ensure adhesion

13. 4. Paraloid method • Suitable for hard surfaces like stone, ceramics, glass and uncoated metals • Application method: • Clean surface with soft clean brush • Test area with swabs dabbed in acetone and petroleum spirits. I f any colour or surface lifts off use tissue/tie method else proceed. • Apply base coat of 20% paraloid B72 in acetone to object surface and allow to dry for 30 minutes. Be careful not to drip adhesive on other parts of object

14. Write accession number on top of base coat with artline drawing system pen or artline paint marker. Ensure no ink leaks out of base coat. Allow to dry. • Apply top coat of 15% Paraloid B67 in petroleum spirit carefully in one stroke , avoiding any drips or smears. • Note: For coated painted metals both layers can be B67 in pet. spirits
