We went to the modern art gallery today; heading to the Dean Gallery tomorrow for the photography exhibition. I took some pics of the earthwork/pond sculpture in front of it and messed about with them: Original: HDRed:

Right, time for an etching update. The Senior Etching Technician at Edinburgh Printmakers has sent me an extremely informative email on his techniques and recipes; interestingly they are using the Bordeaux Etch as well, and have abandoned the Edinburgh Etch in favour of pure Ferric Chloride. I’ve just ordered some Copper Sulphate and Citric AcidContinue reading “Etching, dear?”

Phew we’re feeling more recovered, so here are some pics, blog later: All taken with a 30 quid 2-focus-setting on-sale-discontinued 5MP digital camera from Tescos, now known as “the wee blue beastie”.

I’ve been having a happy afternoon researching chemical suppliers. The two solutions I’ve decided to target are the Edinburgh Etch and the etching solutions using Copper Sulphate. There is lots of information here. I’m going to be studying that website in detail next. The Edinburgh Etch, as I have discovered this afternoon, was in factContinue reading “Etching Chemicals”

Cooool, while I was browsing the web looking for metal plate suppliers last night, I found these guys, Edinburgh Printmakers Studio. They say they would be happy to sell small quantities of supplies to me, so I’ve just mailed them back to find out pricing. Very convenient as they’re based in Union Street. I’d suggestContinue reading “The evening’s etching update”

So, an evening’s research on the portable difference engine later 🙂 It seems Copper Sulphate is the best option, as it is reasonably non-toxic, easily obtainable, and doesn’t generate toxic vapour during the etching process. Another option is Ferric Chloride, which I’ve looked at before for etching circuit boards, but I was always put offContinue reading “Etching research”

Hmmm, anyone know where I can get thin brass plate in edinburgh (or copper)? I’ve just been reading about electrolytic etching and I want to play! I remember trying electroplating things with my chemistry set when i was wee, but it never “stuck” very well: now that we have internets, this problem can be researchedContinue reading “Thin brass plate”

We tried the Garden Sculptures geocache today. Dead fun, will definitely do it again. I especially liked being able to have a wee treasure hunt in the middle of the city as a small break from shopping 🙂 However we couldn’t actually get the cache as there were a couple of teenagers snogging right onContinue reading “geocaching”
