(1) Some of the earliest experiments do not have full individual reports available.
(2) Primarily links to blog postings covering the making of these objects
(3) 'Number of welds' is often estimated, and is the number of 'full sets'. Each 'set' typically includes both hand hammer and machine powered welds - often 3 or 4 individual welding heat cycles.


'Bloom 2 Bar' was a project funded by a grant from the Ontario Arts Council.
