I would try buying in small quantities first, and if you like the quality, you can always purchase more. Also, if you're willing to purify the Lapis, better quality pigment can be made from cheaper stones.Zachary Katorhttps://www.blogger.com/profile/04681785954424203992noreply@blogger.comtag:blogger.com,1999:blog-2230399250812394537.post-51254658855402082022013-07-26T14:53:57.453-07:002013-07-26T14:53:57.453-07:00Where did you all buy Lapis rocks from without hav...Where did you all buy Lapis rocks from without havung to go to Afghanistan then?

Parts 1 and 2 are useful for info on original construction, 3 & 4 deal only with conservation aspects.

It has more detailed instructions about the strength of the lye to be used and more ingredients for making the plastic. Also it describes how to heat the stone before hand. If you would like a copy of the document I will email you it. I'll need an email address to do so.J Tempesthttps://www.blogger.com/profile/16502654625724522728noreply@blogger.comtag:blogger.com,1999:blog-2230399250812394537.post-82532004723063561822011-02-08T19:25:44.571-08:002011-02-08T19:25:44.571-08:00I hadn't heard that, but it wouldn't surp...I hadn't heard that, but it wouldn't surprise me. It hasn't been easy to find information on building panels.

I could always purify it later.<br /><br />I assumed that lye has always been made from wood ash. <br /><br />We use lime or poplar quarter sawn-boards for panel icons. I've bought a 19 inch wide quarter-sawn kiln-dried piece of oak panel but I've been told that with large boards the oak tends to split after being gessoed as it dries out much quicker at the exposed edges.J Tempesthttps://www.blogger.com/profile/16502654625724522728noreply@blogger.comtag:blogger.com,1999:blog-2230399250812394537.post-35638726371742433102011-02-06T19:55:12.330-08:002011-02-06T19:55:12.330-08:00Jules,

I get the feeling something is missing from it. For instance, later on I discovered that what we call lye today and what they probably used in his time are different chemicals.<br /><br />I used a little unpurified lapis on my last painting just for fun. I thought the color was not bad at all. The lapis I used was above average though.Zachary Katorhttps://www.blogger.com/profile/04681785954424203992noreply@blogger.comtag:blogger.com,1999:blog-2230399250812394537.post-24515082551070955232011-02-06T06:50:53.181-08:002011-02-06T06:50:53.181-08:00I'm really glad to have chanced upon your expe...I'm really glad to have chanced upon your experiment with Cennini's method. I have bought some lapis lazuli slabs to make pigment with and was planning to try this method. Did you heat the lapis lazuli prior to crushing it? I've been told that it makes it easier to crush but I haven't tried it yet. Have you had another go at this process? Have you been able to remove the wax from your pigment?J Tempesthttps://www.blogger.com/profile/16502654625724522728noreply@blogger.com
