/ COME next to the fecond way of Refining, fc. by the

becaufe they fwim over it, when they are all melted together. 
The Teji is thus made. They have an Iron Mould, oval, and 
two inches deep^ At the bottom hereof, are three Arches of 
Iron fer at equal diftances, two fingers wide, if the great di- 
ameter of it be fourteen inches long*, andfo propoitionably 
in greater or lefler Tcjl^, 
This cavity they fill with fine powder of Bone-afhes^moiftn-

Pot aflies or other Afhes well cleanfed^ and fo preded well to- 
gether with a Muller,tbat it becomes very clofe and fmooth at 
the top. 
There is left above a Cavity in the midft of if, to contain the 
melted Silver. This Cavity is madegreatefi in the middle for 
the Bone- Aflies come up parallel to the circumference of the 
Mould; only a fmallChannel in that end, which is mofl remote 
from the blaftjfor the running off of the bafcr Metals^ and fo is 
made declive to the centre of the TV/, where 'tis not above 
half an inch deep. 
The TVy? thus made, is fet annealing 24. hours, and then it is 
fit for ufe, in this manner. 'Tis fee in a Chimney a yaid high,
