What exactly do you mean by "nut lacquer" and "chinese lacquer", if I may ask?
Chinese lacquer might be also called Urushi, made from the sap of Toxicodendron vernicifluum/Rhus verniciflua, right? Can't place "nut lacquer" though.

What exactly do you mean by "nut lacquer" and "chinese lacquer", if I may ask? the chinese lacquer is this……Secretions of Toxicodendron vernicifluum(lacquer tree?i dont know its English name)......A traditional lacquer that can only dry in high temperatures and humidity. The Chinese started using it about 6K~7K years ago. The chemical properties are extremely stable ,The film is hard and flexible after dryin.but emulsions that no polymerized contain urushiol,can cause a horrible dermatitis... the nut lacquer, we also call it cashew nut lacquer or synthetic Chinese lacquer here. it's a kind of lacquer made from cashew nut shells. When polymerized it looks a lot like traditional chinese lacquer, but can not be used as cutlery because the catalyst contains Cobalt ions. ....er...What do you call it there?

Cashew Lacquer. But I had not heard of it really. It's phenol based, so it's still relatively toxic. It seems to be sold under the name "Urushi lacquer" as well, so little distinction is made. I think most people here use Acryl, Polyurethane or some other epoxy lacquer, because these are so much less toxic than urushi or phenol. Of course some people still use Urushi, but ther isn't that big a market for it. Shellack is widely used though, but most of the more toxic lacquers are falling out of favour, unless for very specific uses. These newer lacquers are also much less complicated to use.
EDIT: Oh, yeah, in Europe a more widely used historical lacquer, besides shellack, is amber varnish.

but the chinese lacquer(cashew lacquer) has the texture of a horn, extremely strong,excellent thermal stability, Almost resistant to acid and alkali corrosion, and even if the film is several millimetres thick, it will not break. It's hard to find a replacement......

The newer epoxy laquers are equally resistant. Even if Urushi is slightly better at some things, epoxies are less toxic, cheaper, dry quicker, are easier to handle and have better availabilty. This makes them much more attractive to most.

Toxicity on modern formulations is much lower (so low in fact, that they don't even have warnings printed on them any longer) than Urushiol or Phenole (if you look at the chemical structure of both, they are closely related), still you shouldn't be drinking it. Of course you can have allergic reactions to these components as well. You should still be in a ventillated room wearing gloves.
There are so many different epoxy lacquers, that all have different mechanical and curing properties, some cure hard, others a bit softer, some are 2 component, others cure via UV light, so you have to try out a few to find what you like.

I must admit, the Urushiol lacquer does have a special look to it, which isn't easy to replicate, but durability of the epoxies should be equal.
BTW they both look pretty good, I think building a club every group of people will end up with similar designs, I have seen the rounded shape in europe as well. What I find interesting is thze length, the second is pretty long, in the upper range for european maces. Were these usually this long?

Of course, the type of short was also common, the Jurchen soldiers even used it as a standard secondary weapon for each person.

I assume there must be pictures of the males, but they don't show up for me. I see the pictures in the lacquer post, but those are the only pictures that show up for me. Strange.

Now I can't see the pictures any longer, weird. The sword I still can see, but trying to enlarge the image gives me an "access denied" error now.

If it still doesn't work, maybe i need to switch to a new image hosting service ... Sure enough there are no good products for free

The pics for the lacquer are still here, but the maces aren't showing. Sometimes some people can see pictures, others don't if an external hoster is involved, no idea why.
You could just upload the pictures onto the forum (1mb max file size) if nothing else works.
