EricFG and CtahhR,
enamels can be considered glass. As you know glass is an amorphous material. We consider it a solid material but it is technically wrong. It is a high-density fluid. Glass is like a sea. You see it and you think it is only water because our eye can’t ‘understand’ all the currents ( try to think to the Gulf Stream). Hot enamels have a similar effect. Experts knows they have to cool slowly their glass/hot enamels. This process gives the time to amalgamate enamels and eliminate those ‘currents’. They often have to cool slowly their items for hours or an entire day in a special furnace. If you try to cool quickly your item its hot enamels will break. If those ‘currents’ are not perfectly eliminated you item can be damaged by temperature changes. Your item can be perfect for 50 years or have this problem after 5 minutes. When I wrote ‘inclusions’ I was thinking to these ‘currents’ (not bubbles). Soviet made enamels are stronger than European/Japanese ones but they are not indestructible as you know. Try to see your soviet orders with little chips: they have conchoidal fractures. These fractures can be observed on amorphous materials.
CtahhR,
You can’t be responsible if you didn’t damaged it but you have the responsibility to preserve it and its actual conditions. This is my point of view.
