Another letter from Abbe to Schott states:
“A platinum crucible of about 60 ccm volume, with lid and a thick platinum rod for stirring - the whole for about ℳ 100. - I do hope to receive in the next few days - possibly this crucible may provide you some help in your next melts ....” (14).

October 1890:
For the last year the price of platinum has gradually risen; at the end of 1889 the price of rolled ingot metal did not exceed Fr. 1000 to 1100 per kilogram; today the price reached Fr. 2,750 and tends to rise still. Not two years ago Platinum could be sold Fr. 900./kilo.; its price, therefore, would have more than tripled since then.

In 1912, the price for 1 g of platinum was approximately Fr. 7.50. Considering further that the crude platina, which is obtained in the {residue?}, only contains approximately 80% pure platinum, so 1 g of crude platina has a value of .80 x Fr. 7.50. = Fr. 6, or ℳ 4.80, while the value for 1 gram Gold only amounts to ℳ 2.80.
