This year (If all goes well) I am being a foundryman at Kentwell hall, in the year 1588. This is a good opportunity to try various things out, most of which I shall blog about afterwards. So I shall be sure to take a lot of photographs.
Things I intend to do/ show:
Finish my stone pewter spoon mould
Cast pewter buckles which will be used to try and make the next items
Cast bronze and brass buckles, purse bars, scabbard chapes, and pestle and mortar
Experiment with dry powder casting as mentioned in Biringuccio
As well as helping out with attempts at making small cauldrons or a cannon or a bell.
The trick will be preparation, so the week before I shall be mixing up lots of muck for moulds and trying to finish off a couple of pewter buckle moulds. Once there I shall also be discussing foundrywork with a couple of people who know a lot about it, and trying to keep the newbies who don’t, right. And get the younger ones working the bellows.
Yes, I am aware that having a foundry at a 16th century manor house in the countryside isn’t really accurate. It’s one of these irritating compromises that helps keep both the public, the site owner and us re-enactors happy and interested. Ideally we’d have a replica town, but that requires some millions in investment to make happen.
(And don’t say that early medieval association or group has managed it, because I’ll just laugh at you)
Sorry about not posting for a while, I’ve been busy and progressing lots of things at once so nothing is quite finished yet.
I decided ages ago that I would make not direct copies of medieval and Tudor stuff, but attempt to make similar objects. Not only because starting from scratch gives a better understanding of the processes and knowledge required, but also because given the massive variety of surviving objects, I think it pointless to try and produce an exact match to one specific one. Yes, all buckles are buckles, but when you look more closely there are many variations between them, due to the use of many different moulds in different towns over a century or many different copies made. It is the latter I am aiming towards, i.e. how a craftsman would replicate something that is, say, new to town or seen as the latest fashion coming from London. Or that a competitor has designed. Therefore my replicas are often a bit different in size or precise shape.
An example of such variation can be found in the MoL book “Dress Accessories”, where they list 39 medieval pewter buckles excavated in the city of a similar design, i.e. “raised, bevelled band along centre of frame and beading along edge”.. Their diameters range from 21 to 24 mm, which suggests to me at least 3 different stone moulds or else one mould slightly recarved after every few hundred castings due to erosion of the stone, in which case the depth of the buckles should change quite a bit as well. I have trouble believing that each design of buckle would be proprietary to one pewterer or girdlemaker; that they are not helps explain the variation in shape and size. The two they do illustrate have different numbers of beads around the edge and a slightly different cross section.
There is another very geeky reason not to make your reproductions identical to originals, otherwise people might mistake one for the other or try to pass them off as originals. This has accidentally happened to a reproduction potter I know, although it didn’t involve any money, just mis-identification.
