To Mr Faraday
Wednesday
1833 <1>
Dear Sir
Will you allow your assistant while I am absent in the country, to fuse a small quantity of glass for me in a crucible mixed with oxide of Chromium to colour it green. We tried it yesterday, and succeeded in making a yellowish green glass but we had not heat enough.
Have you ever remarked how a capillary glass tube conducts away electricity, it blows through it like wind, I think this is the reason the little arrangement I made yesterday would not act well, nor do I think the arrangement you proposed would act well, if inclosed in a glass tube.
Yours truly
H. F. Talbot
