Faraday to John Frederick William Herschel   25 November 1828

Royal Institution | Nov 25. 1828

Dear Sir

On Saturday I made a piece of glass 5 inches square. On Monday took it to Mr Dollond[.] Today he reports it good with the exception of one run which will grind out[.]

I was excessively cramped in making this piece of glass because of the smallness of our furnace. I have asked Mr Dollond whether he sees objection to laying out £ 10 or £ 15 in constructing a small furnace in the Glass furnace room here which will work properly - he sees none - do you? I shall make sketches & tell Ramsey to give me an estimate hoping that what will be required will not be objectionable[.] I expect the estimates by Friday[.]

Let me know whether you object to this course[.] I cannot make large specimens without some other means than those we have here & I think the large specimen just made is sufficient to prove the applicability of the principles when properly attended to[.]

The piece just made is full of bubbles[.] That was inevitable in the present furnace.

I am dear Sir | Very Truly Yours | M. Faraday

J.F.W. Herschell Esq | &c &c
