joerobson Posted August 3, 2022 Report Share Posted August 3, 2022 15 hours ago, charliemaine said: Hi Joe, I was under the impression that you preferred stainless steel over cast iron. Is there a concern about the varnish turning black over time when cooked in cast iron. Why do you like cooking in cast iron? BTW I ordered one of the Cukor hot plates. How long has yours lasted so far? edit: After reading a few older posts you mention that you like to cook the resin in cast iron and colored varnish in stainless. Does the resin darken better/faster in cast iron? I use SS for varnish. Cast iron for resin. Quote Link to comment Share on other sites More sharing options...

David Burgess Posted August 3, 2022 Report Share Posted August 3, 2022 I like to avoid both copper and cast iron. The acidity of rosin and rosin varnishes will partially dissolve copper into the varnish leaving either a copper-colored or green (oxide) residue. And it will dissolve some iron into the mix, which I highly suspect of causing eventual blackening of the varnish. Quote Link to comment Share on other sites More sharing options...

While the seasoning, if robust and present, will protect the contents from the iron, there's always a risk Colophony contains trace iron anyway, right out of the tree. No need to add more. For cooking resin and varnish, for me glass is it. Quote Link to comment Share on other sites More sharing options...

Samples from the late 90's show no blackening. Perhaps this is because of the old close cast cast iron. on we go, Joe Quote Link to comment Share on other sites More sharing options...
charliemaine Posted August 3, 2022 Report Share Posted August 3, 2022 I’ve got an old cast iron pot from a Creole in Louisiana. The seasoning must be quarter inch thick but think I’ll stick with stainless. Quote Link to comment Share on other sites More sharing options...

Evan Smith Posted August 3, 2022 Report Share Posted August 3, 2022 I tried so many different 120 v hot plates,, I got tired of always waiting for the temp to get up there, so I took a 2500 watt element from off of a stovetop, along with the control, placed it in a nice metal box, and vuwalla oh baby! 220 volts with 2500 watts of smooth power, lots of power, did I mention lots of power and heat, not even on the same planet, smooth,,,, thick copper plate,,,, steady temp,,,,,, sand inside cast iron,,,,, glass in the sand,, massively cool.

Heating surface heats to 400 C in 7 minutes. That’s the limit of my heat gun. With a sand bath it will work fine for varnish making where I use multiple beakers up to 200 C. For cooking color into colophony (220-300 C) without a sand-bath. Of course my setup will change once I finally make a long over due visit to @Evan Smith and get to look at his monster oven-hotplate. Big thanks to @joerobson for showing his hotplate. Quote Link to comment Share on other sites More sharing options...
