1age, as the lowering or toning down of the colour in wood and other materials seems to be caused by similar, if not identical, constituents of the ordinary atmosphere, but under different conditions. Another way is lay the pieces of wood upon a stove with a regulated heating power and watching for the exact degree of change in the colour with continued heat. There is very little to be said against it for small repairs, the degree of heat required for the desired tint is insufficient to damage the wood but enough to harden it, and if not too hastily done the colouring will go quite through.
3Among other methods is tinting the wood by any of the various stains sold for the purpose. Few of them are of any good to the violin repairer, some choking the softer parts and leaving the harder ones or threads standing out lighter when they should be darker. Their colour, if it were not for this drawback, is sometimes good. Some of the manufacturers of new musical instruments on the continent lower the colour of the wood before varnishing by staining it with a solution of bichromate of potash. Sometimes when dexterously applied the colour is very good, but the stain is liable to make itself too evident in parts where the wood may be a little more spongy than at others. Most of the instruments treated in this way may be recognised at a glance, the curl of the maple is brought out strongly, in fact overdone. With small portions of wood for repairing this stain may, with much caution, be used to advantage. It has the property of throwing up the threads of the pine and the nutmeggy parts of the maple without impairing seriously the clearness of the grain under the varnish. The preparation of the solution is as follows—some pieces of bichromate of potash can be put into any ordinary bottle of a convenient size and water poured on to them. The water will take up a certain quantity in solution which will be too strong for the repairer's use; some of it, say a gill, can be put into an equal quantity of clear water, and then painted over the wood to be coloured down. There will not be any perceptible colouring for half-an-hour or so, but further
