Incralac


#1

Blanche, when you mentioned “incrylic”, you may be referring to
"Incralac", which is a lacquer commonly used by bronze sculptors to
seal their patinas. In Ron Young’s book “Contemporary Patination”, he
gives the source as Stan Chem Inc., 401 Berlin Court, East Berlin, CT
06023 (no phone #).

Hope this helps.

The sealant is called Syncrolac ( I think) I haven’t used it in
years. It is a clear micro laqure you can paint or air brush or dip
onto your object. It is impossible to get off when properly cured.
And prevents oxidation. If you have seen brass letters on homes that
don’t tarnish, I think this is the same material. I will post the
supplier and additional shortly.

Hi there, I use Incralac (diluted 50/50 v/v with acetone) for coating
medals. It is manufactured by Wattyl and is available at hardware
stores. Conservators (at least in the US) use either this product or
frigilene to coat silver to prevent tarnishing. Frigilene has a
slightly bluer appearance - apparently to enhance the colour in
silver. Eileen

Is it possible, or I should say, is it a good idea, to put this
sealant – and if so, which one is best? – on big silver items like
trays, vases, candelabra, bowls, decorative objects d’art, etc? My
parents collected such a huge amount of silver from around the world
that, even with it divided among their offspring after their deaths, I
spend entirely too much of my life polishing. Or hiring polishers.
Is this a solution, or would it diminish the value in some way?
thanks for any help… ryr

Rhoda, I keep mine firmly behind glass with a few MMM anti tarnish
strips there also. I understand white chalk will also cut down on the
polishing needs.

I have had to deal with a finish that somehow let air in and the
tarnish spread underneath. That was far worse than the polishing. I’m
not sure I would try it. Teresa

Dear RYR,

I have only tried this product on rings to keep them from tarnishing.
I don’t know how it would work on other objects. You might try a piece
and see what you think. As long as you not eating off it, it shouldn’t
matter.

Hi ryr,

I have a friend who polishes and restores large copper, brass, and
silver items - including coffee/tea services, trophys, etc. He
applies a clear coating called “2105 Clear Lacquer” distributed by
G.J. Nikolas & Co. Inc., 2800 Washington, Bellwood IL 60104. He
polished and coated some floor candlesticks I bought in Thailand which
were the devil to polish. The coating has been on them for over 3
yrs. and it has proved to be very durable… cat urine didn’t even
damage it!! I bought a 12 oz. aerosol can to use on patinaed copper
jewelry to perserve the color and highlights. So far, I’ve been
pleased.

G’day; Would you be surprised to learn that we can even get
Incralac in lil ole Noo Zilnd? Several years ago I came across my 5
British (and one Russian!) WW2 medals kicking around in a drawer, and
wondered if they might be of some interest to another generation, as I
had just finished my memoirs. They’d been shoved around for almost 50
years and were in a bit of a mess, and badly tarnished. Well I cleaned
them up and repolished them, then sprayed them with Incralac. Next I
made a little flat fitted walnut box so they could be seen under a
piece of perspex. I even managed to get new ribbons for them. I
printed their history and put that on display inside the lid. Then it
all got shoved away again in yet another drawer! Because of the
sudden recent interest in Incralac, I fished them out this afternoon
(after I remembered where I’d stashed them). And they looked in
perfect condition. Wonder if great grandchildren will agree? So there
you are. Cheers, –
