This wax is perfectly suited for making hollow items. It is most commonly used as a solid core over which non-soluble wax is applied. When placed in water the soluble wax core is dissolved, leaving only the non-soluble wax behind. To make a core, this wax can be carved with conventional wax tools, or it can be melted (at 170° F) and injected or poured into a mold. Provided in blocks weighing 3/4 lb. approximately. Made in USA.
