Tools like straightedges, compasses, and needle prickers were used to transfer outlines[1][2]. Black iron-gall ink (common writing ink) was widely … Continue reading The Evolution of Architectural Drawing Techniques

The new over-painting of course looked brighter, but the quality and style were a big mismatch with … Continue reading Conservation of wall paintings at Thakur Satyanarayan temple: a brief account
