For perforated crucibles including covers, the weight in grams is 5 grams less than the volume in cubic centimeters.

From Glasgow: Griffin's Catalogue, July, 1841:

Citation: Elements of Agricultural Chemistry (1844)





UK, 1876: Griffin's Catalogue? First ("unused") corresponds to #296 in the 1841 Catalogue; second ("been used") would hypothetically be #301.   75s. to 90s.   Contents 4 Ounces., so approximately (113.7 cc.), 3.65 Ozt.  The weight (1,080 Grains Troy) is low, however: thin metal?



Griffin's Catalogue, London 1877:

Where Crucible 1/2 Imperial Fluid Oz. (14.2065 cc) weighed 0.5833 Ozt (18.1437 g.), ∴
15 cc Crucible = 19.16 g./ .62 Ozt (15cc Crucible Rate: £2.5714/Ozt.) 

Where Crucible 1 Imperial Fluid Oz. (28.4131 cc) weighed 1.14583 Ozt (35.6394 g.), ∴
30 cc Crucible =  37.63g./ 1.21 Ozt (30cc Crucible Rate: £3.00/Ozt.)
