Fix Cinnaber. d'szjsfc

He that desires it , I think he must do thus, break the Cinnaber into pieces as bigasWall-nuts, and put them into a glass vessel that is of the fame bigness, and thepieces must be mingled with thrice the weight of silver, and laid by courses, and thevessel must be luted, and suffer it to dry , or set it in the Sun; then cover it withashes, and let it boil so long on a gentle fire, till it become of a lead colour andbreak not, which will not be unless you tend it constantly till you come so far.7 hen purge it with a double quantity of lead j and when it is purged, if it be put toall tryals,it will stand the stronger, and be more heavy and of more venue: th?,moreeasie fire you use, the better will the business be effected : but so shall we tryjf&re-pair silver, and revive it when it is spoil’d.
