How to prevent the Plastering round Stills from cracking.
This method of making water proof plastering on stills, is done entirely in making the mortar, and putting it on, in making which, good clay and lime are absolutely necessary.
When the mortar for the first coat is thoroughly worked, put as much brock of rye straw into it, as can be worked in, so that when the coat is put on, it may have a greater appearance of straw than mortar, when dry, and covered with the second coat composed of lime mortar, well rubbed and pressed with the trowel until it be dry. A covering put on of those materials, will be found to continue firm and compact without cracking, as in the common mode.[Pg 99]
