< Hans Question: Have you tried to oil paper? With what experiences on a series of parameters:
- Applied before or after folding? both - Ease of application? very easy - simply rub a small amount in the hands; apply - With what kind of oil? refined petroleum jelly - Effect of transparency? depends on the paper/prior treatment.* - Discolouration when applied? no discoloration - Yellowing over time? no yellowing over time - Effect on colours? enhances color - Curing time? no curing time - Greasiness? applied as described there no greasiness - Folding properties? crisp clean folds - Smell? no smell - Toxic? non-toxic - Other remarks? * untreated/dyed/stained papers become a bit translucent with enhanced vibrance of color; paper's flex is enhanced; papers painted with acrylics have a satin sheen and leatherlike quality ORIFUN to all, Dianne On Sat, Nov 6, 2021 at 11:35 AM Papirfoldning.dk <[email protected]> wrote: > I have experimented decorating paper for lamp shades, and to oil them > making the paper more transparent and vibrant in the colours. > > I have mostly tried linseed oil as a) it is harmless (you can eat it) and > b) it has a long tradition in painting furniture, houses etc. I have seen > someone use argan oil, and there is a huge number of other oils available. > > Question: Have you tried to oil paper?
