Mat Makers

Two kinds are made in Toulouse, one to cover rooms’ walls which are finely woven, almost like straw hats worn by villagers, and are made in long rolls, some 10 straws wide, others 13. And they work on them mainly in summer and winter. Then when they prepare it they sew it, but beforehand they dye it in usually three colours: green, red and sometimes purple. The green one is made with only a pastel tincture since green is made from yellow and blue, so the pastel dyes the dark yellow straw. It becomes bright green. For red they use some alum and brazil wood, for purple they use pastel and some coperous which darkens blue with its black tincture.

Glassmakers

They have no way to produce a perfect red that needs to be annealed. Try, however, the German red which is scaled red. They produce their ordinary red with some sanguine, iced pewter, lead rocks, & some iron file dust. This red is to be applied on both sides of the glass because it is more colourful. If it were applied on one side only it would look pastel orange.

Founder

They pay xx lb for a quintal of rosette, which is harder to melt than latten because it is softer. For, the softer the great metals # are, the soft harder they are to melt. The tin used to make bells, which is fine tin is more and which is brittle, is easier to melt than lead, which is soft. Latten, made brittle by the calamine is melted more quickly than red copper. The metal, which is the substance of bells, mixed with tin, and very brittle, is soon melted. The more silver is alloyed, the sooner it melts, that is why solder is made with it. In Germany they make very light candlesticks, it is because they turn them by means of water, but they are breakable. A quintal of per fine coppersmith’s rosette is sold for xxx or 40 lb. Another type used by founders is sold for xii or xv lb. The quintal of metal, six lb.Put in
