Type of blanks and finishes
JSB supplies blanks that are either die cut or laser cut – all blanks are sold as unfinished and will require polishing/sanding or buffing – each listing will specify if the blanks come tumbled – there is an option to pay for tumbling as a new stamper – my tumbling consists of 1 hour in a tumbling barrel to remove light burrs and production muck, this does not mean out of the packet perfect and as previously stated sold as unfinished. Please make sure you blanks are finished and ready to sell on to the public.
Die cut blanks are cut using a die (like a hole punch) hammer or press. They are cut one at a time and orders normally take 1-2 days extra. Their finish is smooth to one edge and crisp on the other and will be supplied as specified in the item listing regarding plastic coatings. Due to the cutting process they may need a slight burr removing with a file to the back of the blank – this is not a fault just part of the normal jewellery finishing process and can be achieved with a normal jewellery file. Top tip is to file in the same direction.
Laser cut blanks are drawn from my specification and cut with a high powered laser which is currently outsourced. Items listed are normally in stock and have been given a light tumbling to removed production muck. The beauty of laser cutting is more detail and the design can be repeated time and time again accurately. The blanks come with a crisp edge to both sides and will require a small laser nobble to be filed off – this is not a fault just part of the normal jewellery finishing process and takes seconds with a jewellery file.
If your blanks have laser burn or scratches try using a nail buffer to start and see if this improves the finish - if not then getting a good range of wet and dry sandpaper/geraflex blocks (proops brothers) or similar and work your way from roughest to smoothest. When stamping first became popular 5 years ago no blanks came tumbled and we all had to finish the blanks ourselves - learning these techniques is worthwhile as well as hammering blanks to hide mistakes whilst giving another dimension.
It is worth mentioning that the more you make your blanks shiny - the harder you have to work to maintain that level all the time :)
