So at last I've got a little time. Been bussy earning money to pay tax and drink and eat, when someone I recently made a bathroom for asked me wether I could make a cast of her baby's little feet. This looked pretty inviting as it produced a scala of problems I've been thinking a lot about the last couple of years.
After several days letting it sink in and occasionally thinking about it I had two options for making the mold in my opinion, ofcourse this was after I got rid of loads of other idears, such as molten wax, or using very soft clay. The two materials left were the dentist stuff, where they make a mold of someone's teeth, and a silicon based material with a very fast pot-life. But after making the first test with the dentist's goo, I immediately realised this was what I was looking for, it even smells like toothpaste ! It is called alginate, you mix it with water and it sets in a minute, after which it is very easy to remove, as it is rubbery, and it gives a mold in which you can define fingerprints. The cast is made of gypsum, extra fine, extra tough, and some acrylic added as well, the only imperfection is the air in the plaster. The mold has been destroyed in the casting, so I'll be doing another round mondays ;)
Have a nice day
Cheers Bo
