epoxy resin fillers

[doctor Bob]

I have a lot of drawer boxes to make which are going to be very rustic looking, lots of knots.
I need to fill these knots with a good pourable black resin or epoxy filler.
What do people use?

The guy from 'Manor Wood Designs' uses Glasscast and their pigments: https://www.glasscastresin.com/
Seems to get good results (but I'm judging by his online videos - not seen it in person)

Not black, but I filled the knots in this brown oak using brass powder and epoxy form: -
Filler

I just dropped them a email asking for advice and they came back almost immediately.
Certainly worth an enquiry.
NB - Remember to seal the back surface of your wood if the knots go all the way through. DAMHIKT

Get any old cheap filler and shove it in everywhere underneath the day before. Epoxy is just slightly thicker than water, but not much. If there is a gap, it will run out.

I bought 1kg of glasscast with a black pigment.
See how i get on with the pour, duely noted about the consistency.

We used west system epoxy recently with brass powder for a lettering infill we were producing a sample of for a client. The epoxy was a nice easy pouring consistency and with some black pigment in should give you a good result judging by our tests. Incidentally our client decided on lasercut metal lettering recessed into the timber instead in the end as they weren’t keen on the finish of the epoxy brass powder mix

West Systems do a black pigment and then they do filler powders to add to change the properties of their glues

try Colloidal silica maybe...

You can fill upside down with that stuff. No need to worry about it running out.

That or microfibres.

Then you could colour it with one of their pigments or graphite powder.
