The ‘Practical Guide to Etching and Other Intaglio Printmaking Techniques’ by Manly Banister is a great book packed with practical instructions and guidance for printmakers. New it is quite expensive, but you can pick up second hand copies on Amazon or Ebay for €10 or €15. Well worth it. Google books also have a few pages you can view online here.
I used the recipe in the book (somewhat simplified) to make my own hard ground for etching and it worked perfectly. All the ingredients were available from art supply shops and online.
You will need (ingredients measured by volume):
- 1 Part Rosin (powdered or lumps ground down to a fine grain)
- 2 Parts Beeswax (Yellow is OK but white is better as it has no impurities )
- 3 Parts Asphalt (Asphaltum or Bitumen as it is also called, powdered or lumps ground down)
- An old mug or ceramic bowl
- An old bucket filled with cold water
- Several pieces of cheesecloth and string to cover the bucket
- An old saucepan for boiling water
- An old spoon or spatula
Prepare the bucket with cold water and tie several layers of cheesecloth (4 or 5) over the top, secured with string or rubber bands, to create a hollow sieve for the mixture. The cheesecloth should be secured to the bucket as you will be rubbing the mixture through the cheesecloth.
Heat up some water in the saucepan to a simmer, place the mug in the middle and slowly add the beeswax, stir with a stick until its melted, then add the asphalt slowly, again stirring until it is melted, then add the rosin slowly and stir.
Once its all melted (and a nice big mess) slowly pour the hot mixture onto the cheesecloth (a little at a time) and rub it through with a spoon or spatula. This sieves the mixture and removes any lumps or impurities. As it drips into the water below it will harden into a ball (or funny shaped worms) which you can remove as soon as its cool enough and shape as you wish. I made a 1″ (3cm) diameter sausage shape and cut this into disks. And that’s it. Now wrap each piece in cling wrap or store in a sealed container to keep it clean and use in the same way as your regular store bought hard ground.
Hallo Annemie, ek is op soek na carborondum poeier, ook genoem silicon carbide volgens Wikipedia. Ek het dit nodig vir teksture met Collagraphy…. Kan jy dalk sê wat word dit genoem in RSA?
Hi Julia, ek weet ongelukkig nie wat dit anders genoem word as carborundum nie… Ek bly ook al vir jare in Ierland, maar het destyds by Herbert Evans Art shop (Rosebank en Fourways?) voorraad gekoop, bel hulle om te hoor of hulle het. Anders probeer uitvind by ‘n universiteit se grafiese kuns afdeling of een van die printmaking studios? Jammer ek kan nie beter help nie.
Baie dankie Annemie. Ek dink dit kan dalk resin dust wees.
Groete daar in Ierland…
Julia, nee resin dust word gesmelt op ‘n metaal plaatjie vir aquatint, ek dink dis te fyn om ‘n goeie tekstuur te gee. Probeer metrolap.co.za, dit lyk of hulle carborundum poeier verkoop. Jy kan ook fyn sand gebruik, of stukkies skuurpapier vasplak? Groete Annamie
