Where the work happens

The only craft in this estate where the workspace itself is a risk the insurer will ask about.

A heat source and flammable material

Melted wax, fragrance oil with a flash point, and an open testing flame, in the same room.

None of it is exotic and all of it is why this is treated differently from a kitchen where somebody makes jam.

What the space needs

A stable, non-combustible work surface for the heat source.

Ventilation, both for fragrance vapor and for comfort.

A fire extinguisher rated for the materials, within reach and not behind the thing that would be on fire. Wax is a flammable liquid when hot, so water is the wrong response.

A separate, level, draft-free area for cooling, undisturbed for hours.

Cool, dark storage for wax and fragrance, and more space than you expect for two weeks of curing stock.

And somewhere safe to burn test for hours at a time under supervision.

The insurance and landlord question

This is the practical one. A domestic property insurer may treat candle manufacture as a business use that changes or voids the policy, and a landlord may have a view.

Tell both. A claim declined because the insurer did not know is the worst version of this, and it is entirely avoidable by a phone call.

A commercial space brings fire code into it, which reaches quantities of stored wax and oil.

Layout

Heat station, weighing station away from drafts, pouring station beside the heat, cooling area out of the traffic, curing and stock storage separate.

The one to get right is the route between the pot and the vessels. That is where a person carries a container of hot liquid, and it should be short, clear and never crossed by anybody else.
