I gather the silver salts used are extortionately expensive, but you also have to take into consideration the costs of running the business, paying staff and the number of years of experience Tim has - he is after all, one of the very top glassmakers in europe and considerably more skilled than professional footballers or pop stars you'd have to pay a fortune to hire to do something for you.
You're obviously all used to buying second hand stuff which is cheap and does not take into consideration the cost of production!
