The size is ready for using as soon as it is completely melted, without having been allowed to boil. Use is frequently made of what is called half-and-half size, a mixture of working size and strong size in equal quantities.
Should the painter be unable to procure manufactured size, the best carpenters' glue is a good substitute for it. This can be obtained almost anywhere, and, in an unmelted
