Talk:Gooch crucible

Later Gooch crucibles

The hazards associated with asbestos as well as the somewhat tedious preparation of the fibre mat has probably rendered this type nearly obsolete. Although the glass frit crucible is closely related I haven't heard the name Gooch crucible applied to that device previously, but the first "Gooch crucible" that I got acquainted with was of porcelain with a porous porcelain bottom. 150.227.15.253 (talk) 10:19, 4 February 2020 (UTC)[reply]

Porcelain introduced 1882?

The article claims that "versions made of porcelain were introduced in 1882", however Gooch wrote already in 1878: "In operations where platinum is liable to receive injury, a porcelain crucible with a perforated bottom, may be used; but this is rarely necessary..." (see page 345 in his article On a New Method for the Separation and Subsequent Treatment of Precipitates in Chemical Analysis). Also the reference given for the claim ("A Porcelain Gooch Crucible") descibes a porcelain crucible with a perforated platinum bottom: "The crucible itself is like an ordinary number six Meissen crucible, except that all but a narrow rim of the bottom is left ont. This rim supports a perforated platinum disk..." Episcophagus (talk) 08:58, 11 June 2022 (UTC)[reply]
