the Aristotle Furnace

This program only offered if specifically requested for 2017

This 16 hour hands on session will introduce the student to the history, construction and operation of the 'Aristotle Furnace'. This is a table top re-melting furnace firing charcoal, which can take almost any iron based material and create a cake of bloomery like metal of controlled carbon content.

This program of particular interest to students of early metalworking, or bladesmiths wishing to find a simple way to experiment with bloomery iron type material.

Saturday will start with an overview of the furnace, followed by each student preparing materials and building their own. In the afternoon, following a drying / pre-heat, several cycles of production will be individually undertaken. Each should result in a roughly 500 gm cake of raw metal.

Sunday, individual students will be guided through the process of using a coal fire to consollodate their cakes into working bars. Also there will be time to run further furnace cycles, perhaps even to forge some small tool edges.

To get the best use of this program, it is recommended that students already have 'intermediate' level experience at the forge, ideally the ability to forge weld. (see Course Requirements.) Session limited to four students, with each provided with their own work station. Students will be able to take home their individual furances (it is suggested you bring a plastic pail or milk crate) as well as a number of metal cakes they have created.

Programs are open to any physically able people, from young adults onwards. (Aged 16 an up - see a special note : Teens as Students). Any students with "learning \ physical disabilities" need to refer to the detail section on Course Requirements. English is the language of instruction. Sorry - the Wareham Forge is not really wheel chair accessible. This program limited to three students only
