Title

[NB003AAA], Technical Note, Hugh De Coursey Hamilton, May 13th, 1887

Editor's Notes

"Hamilton's Exp. No. 1-- Four carbon moulds, each containing 6 bamboo filaments bound together & sealed in a glass tube with enough boiled linseed in it to cover the moulds. Tube is then placed in a sand bath & allowed to stay one hour while temperature is brought up from 75[degrees] to 600[degrees] Fhr. Then taken out of sand & when cooled the tip of tube is broken off for escapement of gas, after which it is entirely broken & moulds taken out. Filaments then washed in benzol to dissolve the oil. After the preliminary carbonization fibres are to be run through the final heat in the ordinary way. Hot oil makes the filaments very pliable, & if they are allowed to remain in benzol more than a minute will curl all up. Appear to be pretty well preliminarized."
