Germany's Prosperity /

But since the glasses like to break and the earthenware vessels, if they are not burned glass-tight, swallow much cheese-water and become crumbly, it would be my advice to perform the cheese-pressing between two silver plates, for the cheese-water does not attack the ☽ Silver. The funnels for this work could also be made of ☽, so one would not have the worry that they would break.

NB. The extraction of the ☉ Gold could also be done through the 🜃 aqua regia into a ☽ flask, so the work would be easier, and no damage could ever happen, which one has to expect hourly with the glass ones. And even if a flask, a press, and a couple of funnels made of ☽ for this work cost about a hundred thalers, the work would soon bring such cost back again, and one could perform his work more safely and quickly. One would have nothing to lose in it but the wages for the work of making the vessels; the ☽ is and remains good and can always pay for itself again. But he who has no ☽, or cannot have any, should use glasses until he can have silver ones made. But the ☽ for these vessels must be fine and hold no ♀ Copper, for otherwise the 🜃 would draw the ♀ out of the ☽, whereby the vessels, and especially the flask, would in time become crumbly.
