I have two East Asian/Chinese soapstone seals/stamps - one is a yin and the other is a yang - I know that these generally state a family or personal name, where they are from, etc. or a saying or proverb --can anyone translate either of these? Also, I think the carvings on each are a pair of dogs (pugs?) - does anyone know the significance of? And lastly, I read on several sites that the way to care for soapstone is to clean using mineral oil - as you can probably see from the photos, I tried this - the problem is that after a day or so they appear almost dried out (something that was not a problem until after I used the mineral oil) - Anyone with other ideas on how to clean or preserve? Any info. would be appreciated!!
