\"Casting<\/a><\/p>\n

I have been sporadically experimenting with my electric micro foundry setup for almost a year.\u00a0 Recently I have been trying different crucibles.\u00a0 My first crucible was a mini terracotta pot.\u00a0 (I don’t know where the pot I used came from but I have not been able to find another one the same size without a drainage hole.)\u00a0\u00a0 I have also used a porcelain crucible (from Ax-Man<\/a>) and a ceramic shot glass that I picked up in Las Vegas.\u00a0 The terracotta pot has some significant cracks and chipping after a couple of furnace runs so it has been retired from use.\u00a0 The porcelain crucible shows some chipping on the top edge.\u00a0 Probably from being manhandled by a pair of pliers during the pour.\u00a0 The ceramic shot glass seems to be holding up the best so far.\u00a0 I don’t see any structural damage after a couple of runs in the furnace.\u00a0 Before I used it I was a little concerned about the design on the side of the shot glass being a starting point for a crack but so far so good.<\/p>\n

Casting small parts in sand is a little more sensitive that larger parts.\u00a0 At least it seems that way since the small imperfections are a more significant portion of the end casting.\u00a0 I tried the small toy airplane (red) in the picture above a couple of times.\u00a0 both times the plane was only partially formed.\u00a0 The tails were too short on one and the wingspan was too short on the other.\u00a0 I will see if I can’t work out some of the bugs in the future.\u00a0 Below are some pictures of my micro furnace in action and some in process pictures of a Yoda and toy plane.\u00a0 I am using old aluminum nails, that I was given, for the raw material in my my micro foundry.\u00a0 Most of my other scrap aluminum would need to be cut down significantly to fit.<\/p>\n
