Liquid glues, such as Le Page’s and “Scoli,” have become popular. The advantages of these liquid glues are that they are always ready for use, requiring no heat, and that they do not spoil by being exposed to the air, though they then become thick, simply from the evaporation of moisture. The remedy, of course, if this happens, is to add a little more water, but in practice, with ordinary care, this is seldom requisite, and is not desirable. In very cold weather a little warmth is necessary, but if kept in a warm room or placed near a fire for a time, liquid glue is soon fit for use. As already stated, it is not applied hot. For work requiring a colourless or almost colourless glue it is unsurpassed, and as it does not set so quickly as the ordinary kind, it is well adapted for marquetry and inlaid work generally. When it does set it possesses great tenacity if properly used, that is, thinly applied and well rubbed in. Although it is not better than best quality animal glue employed under the most favourable conditions, it is certainly superior to ordinary common glue which has not been made, mixed, and used with skill and care. At first sight it may seem expensive, but as a little of it goes a long way, and as it does not waste by keeping, it will be found, when required for occasional use only, to cost in the end but little, if any, more than the usual kind.
