Is anybody surprised? :-)Forrest Higgshttps://www.blogger.com/profile/17208965471464716174noreply@blogger.comtag:blogger.com,1999:blog-4339813531032979196.post-30490437880109969492007-10-18T17:11:00.000+01:002007-10-18T17:11:00.000+01:00This comment has been removed by the author.Forrest Higgshttps://www.blogger.com/profile/17208965471464716174noreply@blogger.comtag:blogger.com,1999:blog-4339813531032979196.post-1780822763551884792007-10-18T17:10:00.000+01:002007-10-18T17:10:00.000+01:00"THERMAL PROPERTIES : The incorporation of mica re..."THERMAL PROPERTIES : The incorporation of mica reduces thermal expansion and helps to eliminate the non-uniform thermal shrinkage and causes warping it also reduces mould shrinkage and facilitates mould release.

You can roll your own but at the rate I am using it that is not practical.<BR/><BR/>HDPE looked promising because it is widely available as welding rod and also offers the possibility of recycling milk bottles. It also produces items that can stand boiling water.nopheadhttps://www.blogger.com/profile/12801535866788103677noreply@blogger.comtag:blogger.com,1999:blog-4339813531032979196.post-45862920338551806102007-10-18T11:37:00.000+01:002007-10-18T11:37:00.000+01:00Why aren't you using capa? i thought it was much e...Why aren't you using capa? i thought it was much easyier to work withAnonymousnoreply@blogger.com
