 So when you have your draft then you want to carve the decoration and what we know that they use we get constructed on the traces we analyzed in the the laboratory of tribology in Lyon okay so we know that they used this kind of little cutting discs so probably in copper because it was softer enough you know to grip the abrasive border oh yes to make you know the abrasion more efficient right right so the same type of corandum powders or maybe diamond borders were used to carve all the details okay okay you know the decoration so first they have to realize it's a very complicated process and maybe that's going to be clear when we will handle the objects right but first they're green down all the area you know because okay sorry that's right because the for instance the viewers and so on got a relief decoration okay so that's mean that all the designs are made on what we call eyelets of relief which stand throughout of the rest of you know the world right the first they have to bring down all the lower portion you know of the worst right so we still don't know yet exactly what type of you know tool they use but it is really it's almost sure that they use what we call grinding wheel or grinding discs okay so two options first was probably that type of grinding wheels okay so they've got they were of different size right yeah okay so for the the large abrasions or a large portion of abrasions so they probably used a bit smaller but maybe this type of grinding wheel with abrasive but we don't know if first option the abrasive was already stuck okay yeah on the wheel right so like a sanding paper disc yeah exactly exactly so this is the option we tried on the other side sorry that's fine up you've seen here oh yeah okay it's already stuck on it yeah okay so here for instance this is the corandum powder uh maintained on the copper disc using um beeswax oh okay and resin as well okay and it's pretty efficient so you have just to pull water during the abrasion process so they could be of different size but also they are grained the abrasives inside could be of different size and you know hardness as well right and then you could use the same wheel and melt it off absolutely renew it easily or yeah or you could have multiples depending on yeah the size of your shop absolutely yeah it's different uh so this is the first option the second option would be to use uh the the flat part of the copper disc okay I said copper but iron soft iron can be a good option as well but I you know more inclined to think that you know copper was okay but still you know iron or soft steel as well yeah yeah there's a reconstruction with soft steel on a stone cutting saw in Germany oh yeah right yeah right right and this is exactly the same process that they use in China for instance you know for jade so you have just to scorn the disc you know to grip to provide more you know grips with the abrasion during the rotation and for a small portion of course you had smaller grinding wheels you know right right and of course if you coat all the surface of the disc you can use this part as well yeah which is extremely useful you know during the rotation when you're going to a broad snowboard okay and that would be also the way that you could create a vessel with facets like there's a wonderful vase in the the getty oh yeah it's all faceted absolutely so this is exactly the artist to this kind of process okay to create the facets yeah okay sure sure so then to cut the details like the lines you know the curve the spirals as well and so on they used well okay this type of little cutting disc as well in probably in copper okay steel with abrasives and lubricant okay so in theory I maybe this is we are trying to analyze that we did some replicas of you know cuts made with the copper disc using whether water or oil and we are going to analyze the traces okay from that to be sure of what type of lubricant they use right right in India for instance when I was in India for this kind of decoration they use oil okay okay with diamond powder but current them could be a very good as well right yeah right so just to show you how it works so it could have been made if the cover was extremely well experimented and so on by the cover alone or with an assistant you know okay running the lathe while uh the uh master color so you're looping this yeah you're looping this through okay all right so that grips it and then you draw it like a bow yeah indeed so it's supposed to be attached with clips but oh we don't have today and here it is okay you know and you can apply then the crystal yeah yeah yeah okay okay like that oh wow and here we have a small bow so you know it's not fast very fast but if you have a longer bow you can acquire very if you can have a rotation you know it's yeah fast and so on
