Germany, 1852: Eduard Gressler Catalogue

1852, Eduard Gressler = Eduard Greßler of Erfurt (Thüringen, Prussia: Berlin Weights)

April, 1851: 1 Troy Ounce Platinum (Mkt) = Thlr. 9.26 ($ 5.55)
1851: 1 Troy Oz. Platinum (Saxony: Semi-Mfg, Retail) = Thlr. 14.36 ($ 8.61)

1852: 1 Ozt. platina (Erfurt: Ore, Ret.) = Thlr. 10.64/ Fl. 15.96 ($ 7.61)
1852: 1 Ozt. Platinum (Erfurt: Foil, Ret.) = Thlr 11.70/ Fl. 17.56 ($ 8.36)
1852: 1 Ozt. Platinum (Fine Foil, Ret.) = Thlr 13.30/ Fl. 19.96 ($ 9.50)

1852: 1 Ozt. Platinum (Wire, Ret.) = Thlr 11.70/ Fl. 17.56 ($ 8.36)
1852: 1 Ozt. Platinum (Fine Wire, Ret.) = Thlr 12.77/ Fl. 19.15 ($ 9.13)
1852: 1 Ozt. Platinum (Ultra Fine Wire) = Thlr 15.96/ Fl. 23.94 (USD$ 11.41)

1852: 1 Ozt. Platinum (Ger: Mfg @ Thlr. 6.50./Loth, Ret.) = Thlr 13.83 ($ 9.88)
1852: 1 Ozt. Platinum (Ger: Mfg, Crucible) = Thlr 12.50 (USD$ 8.94)


See Erfurt Weights. The Erfurt Commercial Pfund (16 Unzen, 32 Loth) weighed 0.467 Kilogram, or 15.04 English Troy Ounces,  1 Loth = 14.616 g or ~0.47 Troy Ounce.

The Nuremburg Pfund weighed 0.358038089 Kilogram  or 11.51 English Troy Ounces, but in practice, not divisible by Loth

Where 1 Liter (1,000 cc) = 61.028 Cubic Inches and 35.195 Imperial/UK Fluid Ounces and 33.814 US Fluid Ounces; where the English Pint ('Wine Measure') is 28.875 Cubic Inches (0.4732 Liter, 473.1765 cc), 31.1035 cc contains 1.095 UK Fluid Oz. /1.052 US Fluid Oz.

For Foil or Sheet (unknown thickness;weight) ~ Thlr 0.36 (USD$ 0.26) per sq. in.
2 quadzollen = 1.858 English Square Inches = Thlr 0.67 (USD$ 0.48)
8 quadzollen7.432 Eng. Square Inches = Thlr 2.67 (USD$ 1.91)
18 quadzollen 16.722 Eng. Square Inches = Thlr 6.0 (USD$ 4.29)

The cubic ounce (dry capacity, or content/volume) is presumably the same water volume; therefore weights of 'same size' manufactured Platinum containers should be similar.



This approximates the same 1838 German price for Döbereiner's cited laboratory crucible costs.  Compare other crucible weight/volume and contemporary British crucibles for approximations.

1 Unze Volume, Crucible w/ cover ~ 25 g. or 385 grains = 0.80 Troy Ounce
2 Unzen Volume, Crucible w/ cover ~ 50 g. ... = 1.608 Troy Ounce
3 Unzen Volume, Crucible w/ cover ~ 70 g. ... = 2.251 Troy Ounce
4 Unzen Volume, Crucible w/ cover ~ 95 g. ... = 3.05 Troy Ounce

1 Unze Inhalt: Lid cost Thlr 2. or 25% extra.

Evaporating basin @ Thlr 8./ per Unze (volume)

Crucible w/ cover @ Thlr 10./ per Unze (volume) 


Citation: Preis-Courant von Eduard Gressler zur Erfurt (1852) pp.




Schmelztiegel mit Deckel, Inhalt = crucible w/ cover @ Thlr 10./ per Unze (volume)

By Volume, a 'Crucible with Cover' containing 29.2 Grams cost Thlr. 10.; theoretically, 
a 'Crucible w/Cover' containing 30 Grams {Metric} should cost Thlr 10.27, 60 Grams @ Thlr. 20.55, 90 Grams @ Thlr. 30.82, 120 Grams @ Thlr. 41.10, etc. 


Assuming an approximate thickness & form, the difference between covered crucible & dish is the COVER- and handle-weight (accounting for extra labor.)

Abdampfschaalen = evaporating basin @ Thlr 8./ per Unze (volume)


By Volume, a 'Basin' containing 29.2 Grams cost Thlr. 8.; theoretically, 
a 'Crucible with Cover' containing 30 Grams {Metric} cost Thlr.8.22
Thlr. 12.33, Thlr 16.44, Thlr. 20.55 ... 
1852: 1 Ozt. Platinum (Ger: Mfg 21.81 Gr; Ret.) = Thlr 11.41 (USD$ 7.87)
1852: 1 Ozt. Platinum (Ger: Mfg 57.74 Gr; Ret.) = Thlr 10.77 (USD$ 7.43)







Grove's Battery: Small 4.5 Thlr (USD$ 3.57; Large 9 Thlr (USD$ 7.14), apparently more expensive than US batteries (see Wightman, 1853.)
