No other applied reagents, nor tissue texture or processing showed any influence on the colour. Blue colour from provider A changed during immunohistochemistry into black, when 3,3′-Diaminobenzidine-tetrahydrochloride-dihydrate (DAB) and H2O2 was applied as an immunoperoxidase-based terminal colour signal. Immunohistochemistry was performed manually via stepwise omission of reagents to identify the colour changing mechanism. TMD (blue, red, black, yellow and green) obtained from three different providers (A, B and C, and Whiteout/Tipp-Ex®) were used. Tissue specimens were marked with various TMD and processed by two different methods. In this context, our group observed colour changes during routine immunohistochemistry. Therefore, the correlation between the applied TMD during macroscopy and the examined TMD during microscopy is crucial for the correct orientation, the residual tumour status and the subsequent therapeutic regime. In some cases (e.g., close margin), additional immunohistochemical analyses can be necessary. Pathological biopsy protocols require tissue marking dye (TMD) for orientation. Conclusion: Nail enamel can be used as an alternative to India ink because of its less drying time, ease of application, good visibility on wax blocks and microscopically, availability in multiple colours, cost effectiveness and non-toxicity. However, processing fluids contamination is the main drawback of nail enamel. Microscopic visibility of nail enamel was comparable with that of India ink. Results: Less drying time and visibility on paraffin wax block were excellent for nail enamel. After routine processing and staining, the effectiveness of nail enamel and India ink were compared based on macroscopic and microscopic parameters. Each selected margin is divided into 2 equal halves and one is inked with India ink and the other with nail enamel (Vernis A Ongles: Dark green).

Materials and methods: N = 20, which included 10 mucosal and 10 skin samples. The aim of this study is to evaluate the effectiveness of nail enamel for inking of surgical margin and to compare it with India ink. Because of these disadvantages, alternative materials have been suggested to replace India ink. The main disadvantages of India Ink are longer drying time, monochrome, toxicity and cost. Your drawings come to life through colouring with the intense colour ink.Īirbrush, feather, and line drawing techniques are achievable.Īll our paints are made in our factory in Wandre, Belgium.Background: India Ink is the most commonly used ink in surgical pathology. Without varnish, the paint will withstand water but may lose colour intensity over time due to exposure to UV light.Ĭlean your equipment with cold, soapy water. You can apply a Darwi matte, satin or gloss varnish to protect the achievement. When you paint the ink colour on it, the drawing will appear.Īfter a few minutes the paint is dry and provides a matte finish. You can prepare your paper beforehand with pastel or wax drawings. Use a soft brush to avoid brush streaks and watercolour paper that will keep the good quality of the colours and thus the final result, unlike printer papers. If you want to reduce the intensity of a colour, simply dilute it with a little water. Prepare the colours you will use and any mixtures of colours to create new shades. The application can be made by brush, airbrush, pen to write or draw or drawing line. This gives an old look to Darwi or Cernit clay creations. The gold and silver colours are particularly appreciated for creating a patina on embossed creations (on Darwi cracking varnish or a painting created with a structural paste). Inks can be diluted with distilled water to reduce the colour intensity. They are all mixable together to create opaque pastel tones (with white) or new tones. The range consists of 4 opaque colours (white, gold, silver and black) and 10 transparent ones.

INK liquid ink is made from water and shellac.
