the foam is burned away when aluminium is poored into the mold
think i used brusselse aarde
no i used bindolzand (rode kneedbare zand / red sticky sand)
from http://www.hazelaar.nl 25kilo = 44 euro

a petrobond sand mold. ?

wasted my motor gloves because off extreme heat

i do not understand the price i payed for the scrap aluminium
on the londen metal exchange LME
the price is 2700 usdollar per 1000 kilo
2.7 dollar per kilo
2.7 U.S. dollars = 1.82679296 Euros
1.82 euro * 22 kilo = 40.18euro and i paid 25 euro
could get sleeping rich if i where a scrap metal dealer

An average aluminium can (without its contents)
weighed 16.55 grams in 1992.
By 2005 the aluminium can weighed about 14.7 grams.
thats 68 / 69 cans in a kilo
aluminium can price is 1.5 usd a kilo or 1500usd per ton

so this skull is aprox 345 cans

Aluminium has a melting point of 660°C
compared with 1540°C for iron

If all the aluminium cans sold in the UK were recycled for cash it would raise more than £30 million for collectors.
Setting up an aluminium can recycling scheme is a great way to raise funds for a charity or good cause without having to ask for donations.
