Plates need to be varnished, at least if you want them to last for quite a bit and at first I used Liquitex varnish which is a contemporary method. I don’t like it. It smells bad, sticks like a mad man and I could not get it to flow over the plate easily. Carl mentioned I should try and heat up the stuff “au-bain-marie-style” and haven’t tried that yet but decided to buy the traditional varnish anyway.
This varnish consists of a mixture of Sandarac which is a resin from a North African conifer, Ethanol and Spike Oil. Spike oil is a lavender oil and (obviously) smells really pleasant. Even the Sandarac smells really good on its own. The formula used is the following:
400 mL Ethanol
60 gr Sandarac
40 mL Spike Oil
First you have to grind the Sandarac, it comes in a crystalized shape, until it’s a powder. Then you have to dissolve it in Ethanol. When that has taken place add the spike oil and filter, filter, filter until it’s absolutely clean. The sandarac can come with residues from the tree, small animals etc. Filtering these out is very important!
Some photos (nvm the iPhone “qual”):
I’ll post how it looks when dissolved tomorrow. I wish I could post its smell 😉
