Bones of Burgos
Simple question: did the use of heated shot increase the likelihood of the gun bursting?
Thanks both. The same enquiry elsewhere has directed me (thanks to Rob Griffith) to this treatise, which explains the procedure and associated risks very clearly. See pp.132-134 of the artillery section (597-599 in the PDF's numbering): https://www.google.co.uk/books/edition/Treatise_on_Fortification_and_Artillery/aGXzAAAAMAAJ
Heated shot was considered dangerous
I think this was discussed here earlier.
Heated shot was fired from mortars. I don't think these were fired from fieldguns. And mortars are not likely to burst.
