  • Frixion pens for underpainting?ApproveRejectUn-ApproveSubscribeUn-Unsubscribe
    Question asked 2018-02-05 11:11:56 ... Most recent comment 2018-02-06 02:30:19

    ​Hi all,

    I was wondering whether anyone had any thoughts on using Frixion pens for underpainting? The idea being that even under transparant paint the drawing can be made transparent with the application of heat..

    I know that the ink they use becomes transparent at 65C and then stays that way until the temperature is lowered to -15C. 

    I don't know if subjecting oil & acrylic paint on top of the ink to temperatures that high for enough time to activate the fading process in the ink would cause damage to the paint films?

    Has anyone done any tests or studies on this, or seen artists using them for underdrawing?

    Thank you,

    ​I think I am confused as to what particular benefits these types of pens can offer...apologies if I missed something! As with most materials used in art, if it is difficult to get a fairly clear idea as to the chemical components present in something then it is hard for us to make any endorsements. Even materials of known composition require certain types of testing (I am referring to ASTM testing here) before we can recommend them for specific purposes. Can you please clarify what aspect of these pens you are after in particular so that we can try to offer somewhat helpful advice?

    ​Hi Kristen,

    What I was thinking about was doing an underdrawing using these pens, spraying with fixative and then painting over. If there are any areas that have a transparent pigment and the lines of the drawing are showing through then they could be made invisible with the application of heat.

    But I don't know if 65c would be dangerous for the acrylic or oil paint film..

    ​That specific temperature is not great for acrylics or young oil films to be quite frank. You should also consider the impact local heat will have on your ground, size, and support. I suppose you are avoiding something like charcoal for a specific any case I do not think many of the moderators would be 100% endorsing this material or even this specific technique until more research has been done. However, if you yourself decide to do a fews on your own please share your findings with the group!

    ​Thank you Kristen.

    That's fine, it was just an idea that I wondered if it would work without damaging the paint/surface.

    Now you've confirmed that there are risks I won't try it :)
